Therefore, the only solution to the system of inequalities is (0,0).

An equation is a mathematical statement that shows that two expressions are equal. It typically consists of variables, constants, and mathematical operations. Equations can be solved by manipulating the expressions to find the value of the variables that satisfy the equation. Equations can be used to model real-world situations, and they are an important tool in many fields, including mathematics, physics, engineering, and economics.

Here,

Let's check each point if it satisfies the given system of inequalities:

1. (-2,5)

3x + 4 = -7, which is true since -3(-2) + 4 = 10

y < 3x - 2, which is true since 5 < 3(-2) - 2

Therefore, (-2,5) is NOT a solution to the system of inequalities.

2. (0,0)

3x + 4 = 4, which is true since -3(0) + 4 = 4

y < 3x - 2, which is true since 0 < 3(0) - 2

Therefore, (0,0) is a solution to the system of inequalities.

3. (3,13)

3x + 4 = -5, which is false since -3(3) + 4 = -5

y < 3x - 2, which is false since 13 < 3(3) - 2

Answer: Let's first find out the original price of the watch, before any discount was applied.

Since Libby paid $600, which is 80% of the original price, we can set up the equation:

0.8P = 600

where P is the original price of the watch.

Solving for P, we get:

P = 600/0.8 = $750

So the original price of the watch was $750.

Now, we can find the discount that was given to Scott. He paid $630, which is a discount from the original price of:

$750 - $630 = $120

So the discount amount was $120.

To find the percentage discount, we can use the formula:

Discount percentage = (discount amount / original price) x 100%

Plugging in the values, we get:

Discount percentage = (120 / 750) x 100% = 16%

Therefore, Scott received a 16% discount on the watch.

Answer: 8.4

Step-by-step explanation:

Rearrange the equation: 4x = 40 - 8y

Substitute 0.8 into the equation

— 4x = 40 - 8(0.8) = 40 - 6.4 = 33.6

Divide both sides by 4

— x = 8.4

Answer:

8.4

Step-by-step explanation:

8 x .8= 6.4

40 - 6.4 = 33.6

33.6 / 4= 8.4

4 x 8.4= 33.6

8 x .8= 6.4

33.6 + 6.4 = 40

The correct relationship most likely reflects both correlation and causation is Eating burgers more often is associated with eating french fries more often.

What is correlation?

Correlation refers to the statistical relationship between two variables. In other words, it measures how closely two variables are related to each other. A correlation can be positive, negative, or zero, depending on the direction and strength of the relationship between the variables.

However, correlation does not imply causation, which means that even if two variables are strongly correlated, it does not necessarily mean that one causes the other. There may be other underlying factors or variables that are responsible for the observed correlation.

The relationship that most likely reflects both correlation and causation is:

According to the given question, by calculating the total time spent by Connor we can conclude that Connor will deliver newspaper in 2 hours and 16 minutes.

"Time" has no clear beginning, middle, or end. An interruption in time is called an interval. It has a start, an endpoint, and a set amount of time.

To find the amount of time Connor spent actually delivering newspapers, we need to subtract the time he spent cooling off and having a soda and the time he spent talking with a customer from the total time he was on the route.

First, we need to calculate the total time Connor was on the route:

5:56 p.m. - 3:25 p.m. = 2 hours and 31 minutes

Next, we need to subtract the time he spent cooling off and having a soda:

2 hours and 31 minutes - 11 minutes = 2 hours and 20 minutes

Finally, we need to subtract the time he spent talking with a customer:

2 hours and 20 minutes - 4 minutes = 2 hours and 16 minutes

0.1 gallons per second is the unit rate in the given situation.

An item's unit rate is its price for one of them.

This is expressed as a ratio with a one as the denominator.

For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second.

Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.

The denominator of a unit rate is always 1.

Hence, divide the denominator by the numerator so that the denominator equals one in order to determine the unit rate.

The unit rate is 50km/5.5 hours = 9.09 km/hour, for instance, if 50km are traveled in 5.5 hours.

The Area of the shaded portion will be 54.5 [tex]cm^{2}[/tex]

In the figure which is provided let's name the triangle  ∠ABC, therefore AB= the diameter of the circle

     And, AC=6 cm and BC=8 cm

To calculate the area of the shaded portion we know that ∠ACB= 90°

And then applying Pythagoras' Theorem, we get -

  AB=[tex]\sqrt{(AC)^{2}+ \sqrt{(BC}) ^{2} }[/tex] = [tex]\sqrt{(6)^{2} }+ \sqrt{(8)^{2} }[/tex] = 10 cm

  Diameter AB= 10cm

   The radius of the circle = [tex]d\\ 2[/tex] = 5 cm

Area of Circle= π[tex]r^{2}[/tex] = 3.14× [tex]5^{2}[/tex] = 78.5 [tex]cm^{2}[/tex]

Area of triangle ABCD  =[tex]\frac{1}{2}[/tex]× AB× BC

                  =[tex]\frac{1}{2}[/tex]× 6×8 = 24 [tex]cm^{2}[/tex]

Now,

The Area of the shaded region = Area of the circle - Area of the triangle

                                                     =  (78.5 - 24) [tex]cm^{2}[/tex]

the answer of the subsets of the questions are Angle BTC is 198 degree

Arc bd is 90 degree,

How to find the Arc of the circle?

Since points T, C, B, D are on the boundary of a circle and meet at point P, we can conclude that P is the center of the circle.

Let's label the angles at the center of the circle. Since the angle between TCP is 128 degrees, we know that the angle TPC at the center of the circle is twice that, or 256 degrees. Similarly, since the angle between TPB is 90 degrees, we know that the angle TPB at the center of the circle is 180 degrees.

Let's also label the points where the arcs intersect the circle. The arc BD intersects the circle at points B, D, and P. The arc BC intersects the circle at points B, C, and P. The arc BTC intersects the circle at points B, T, C, and P. The arc TDC intersects the circle at points T, D, C, and P.

To find the arc BD, we need to find the central angle that corresponds to that arc. We can do this by adding the angles at the center of the circle that correspond to the arcs that intersect BD. In this case, those angles are TPB and TPC. So the central angle corresponding to arc BD is:

central angle for arc BD = angle TPB + angle TPC

central angle for arc BD = 180 degrees + 256 degrees

central angle for arc BD = 436 degrees

Therefore, the arc BD is a 436-degree arc.

To find the arc BC, we can follow the same process. The angles at the center of the circle that correspond to the arcs that intersect BC are TPB and TPC. So the central angle corresponding to arc BC is:

central angle for arc BC = angle TPB + angle TPC

central angle for arc BC = 180 degrees + 256 degrees

central angle for arc BC = 436 degrees

Therefore, the arc BC is also a 436-degree arc.

To find the arc BTC, we can again follow the same process. The angles at the center of the circle that correspond to the arcs that intersect BTC are TPB and TPC and the angle at the center of the circle that corresponds to arc BC. So the central angle corresponding to arc BTC is:

central angle for arc BTC = angle TPB + angle TPC + angle BPC

central angle for arc BTC = 180 degrees + 256 degrees + (360 degrees - angle BC)/2

central angle for arc BTC = 436 degrees + (360 degrees - angle BC)/2

To find angle BC, we can use the fact that the angles in a triangle sum to 180 degrees. So:

angle B + angle C + angle TCP = 180 degrees

Since TCP is 256 degrees, we can solve for angle BC:

angle B + angle C = 180 degrees - 256 degrees

angle B + angle C = -76 degrees

Since angles in a circle cannot be negative, we made an error somewhere. In fact, it is not possible for the given angles to correspond to a circle with center P. If we assume that the given angles are correct, we can conclude that there is no circle that contains all four points T, C, B, and D.

Atmospheric gases move according to their densities as one material rises above another. It affects what floats and what starts to sink in a body of water. A estimate of how compressed matter is is what density means. How much "stuff" is crammed into an area, to put it simply.

It is a calculable and manipulable formula in mathematics. Density is used to discuss population in various fields, such as the social sciences.

Density = mass / volume

mass = density * volume.

density of steel =  7.95 g/cm³

volume of steel = 1,015 cm³

Unit rate =  $0.29 per kilogram

mass = 7.95 * 1,015 g

mass = 8069.25 g

mass of 500 parts = 500* 8069.25

mass of 500 parts = 4034625 grams

mass of 500 parts = 4034625/1000 = 4034.625 kg

Total Price = mass of 500 parts *Unit rate

Total Price = 4034.625 * 0.29

Total Price = $1170.04

The circumference of Circle B is 34.5 meters.

What is circumference ?

Let's start by finding the diameter of Circle A. The formula for the circumference of a circle is:

C = πd

where C is the circumference and d is the diameter.

So we can solve for the diameter of Circle A by rearranging the formula:

d = C/π = 23/π

Now we can find the diameter of Circle B, which is 1½ times as long as Circle A's diameter:

d(B) = 1.5d(A) = 1.5(23/π)

Next, we can use the formula for the circumference of a circle to find the circumference of Circle B:

C(B) = πd(B)

C(B) = π(1.5)(23/π)

C(B) = 1.5(23)

C(B) = 34.5 meters

Therefore, the circumference of Circle B is 34.5 meters.

What is diameter of circle?

The diameter of a circle is the distance across the circle passing through its center. It is the longest chord of the circle and is twice the length of the radius.

The formula for the diameter of a circle is:

d = 2r

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b. where m is the slope and b is the y-intercept.

The equation y = 20 + 10x represents the total amount the gymnast pays per month for his membership to the yoga studio, where:

y is the total cost per month, in dollars

x is the number of classes the gymnast attends per month

The equation has two parts:

The constant 20 represents the fixed monthly fee the gymnast pays, regardless of how many classes he attends.

The term 10x represents the additional fee the gymnast pays for each class he attends. Since the coefficient of x is 10, the gymnast pays $10 for each class he attends.

Therefore, if the gymnast attends x classes per month, his total monthly cost would be:

Total Cost = Monthly Fee + Cost per Class * Number of Classes

y = 20 + 10x

For example, if the gymnast attends 3 classes per month, his total monthly cost would be:

y = 20 + 10(3)

y = 20 + 30

2x=138

X=138/2=69

Therefore, the speed of boat is 69 miles per hour or

The boat in the problem travels different distances at different rates, but in the same amount of time for each trip. Distance is rate times time, d=r⋅t, which, solving for t, becomes

t=dr.

The trip against the current has rate r=s−3, so the time it takes to complete the trip is

t=20s−3.

The time it takes to complete the trip with the current is

t=22s+3.

The time to complete each trip is the same, so set the fractions equal to each other.

20s−3=22s+3

Multiply each side by (s−3)(s+3).

20(s−3)(s+3)(s−3)=22(s−3)(s+3)(s+3)

Simplify.

20(s+3)=22(s−3)
