Answer:

[tex]x+y=13\\10x+9y=122[/tex]

Jose worked on washing cars for 5 hours and on walking dogs for 8 hours.

Step-by-step explanation:

Given that:

Jose works for two summer jobs.

Earnings per hour by the first job i.e. by washing cars = $10

Earnings per hour by the second job i.e. by walking dogs = $9

Total number of hours worked = 13 hours (30 hours does not give us proper answer, it must be 13)

Total money earned = $122

To find:

System of equations to find the number of hours that Jose worked on each job?

Solution:

Let number of hours worked on washing cars = [tex]x[/tex] hours

Let number of hours worked on walking dogs = [tex]y[/tex] hours

As per the question statement, we can write the following system of equations:

[tex]x+y=13 ..... (1)\\10x+9y=122 ...... (2)[/tex]

Let us use the Elimination method to find the values of [tex]x[/tex] and [tex]y[/tex].

Multiplying the equation (1) by 10 and then subtracting the equation (2) from it:

[tex]y = 130 - 122 = 8\ hours[/tex]

Using the equation (1):

[tex]x = 5[/tex] hours

Therefore, Jose worked on washing cars for 8 hours and on walking dogs for 5 hours.

Answer:

£15

Step-by-step explanation:

We know that Carly works 6 hours each day for 4 days. This means she works a total of 24 hours per week.

In addition, we know that she makes £360 per week.

Therefore, let [tex]x[/tex] be the amount in £ that she makes per hour:

[tex]24x = 360 \text{ // Divide by 24}\\x = 15[/tex]

Carly earns £15 per hour.

Answer:

25x + 15800

Step-by-step explanation:

Given

The amount of money in both banks over time represented  by the functions;

f ( x ) = 50 x + 6500 and  g( x ) = − 25 x + 9300

The total amount of money in the two accounts over time is expressed as;

h(x)= f(x) + g(x)

Substitute;

h(x) = 50 x + 6500 + (− 25 x + 9300)

h(x) = 50x - 25x +6500+9300

h(x) =25x + 15800

Hence the sum of the money in the account over time is 25x + 15800

The age of the person who entered the room is 26.

From the information, the ages of the people are

23 , 19 , 12 , 21 , 13. Therefore the addition of the ages will give 88.

When another person entered, the person enters the room, the mean age of the 6 people is now 19. Therefore, the total ages will be:

= 19 × 6

= 114

Therefore, the age of the last person will be:

= 114 - 88

= 26

Therefore, the age of the person who entered the room is 26.

Answer:45.36 FEET PER SECOND GET IT IG

Step-by-step explanation:

The most accurate determination for the number of feet per second Tyrone traveled on his way to work is D. 45.36 feet per second

Given the parameters:

time= 58.2 minutes

distance= 30 miles

Therefore, we would convert and solve:

(30*5280)/58.2*60

=158400/582*6

=158400/3492

66.6(repeating)

Step-by-step explanation:

The ratio of the sides are 3:8.

The other pentagon's ratio is 25:x

To find the ratio, you need to divide 25 by 3 and then multiply that number to 8, which gets you 66.6 repeating

An equation shows the relationship between variables and other quantities in a situation​, by equating the constraints of the situation.

The variable is the unknown part of the equation that can take any value according to the equation.

Properties of an equation can be defined as-

They are the expression which consist the variables, coefficients of variables and constants having an equal sign in between.

The example of an equation can be given as:

y = 5 x + 10

Lets assume here that the variable (y) represent the charge of taxi and variable (x) represent the number of rides the taxi traveled.

Here the constant 10 is the fixed amount which is charged by the taxi driver and coefficient of (x) 5 is the rate by which the the value of x increases with respect to y.

Therefore, an equation shows the relationship between variables and other quantities in a situation​, by equating the constants of the situation.

Answer: I think it’s y = mx+b?

Step-by-step explanation: well if you really need it-

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

Answer:

Yes,it is a right triangle

Step-by-step explanation: use pythagorean theorem: 4.5^2+6^2=7.5^2

The measure 4.5 inches, 6 inches and 7.5 inches together form a triangle.

A triangle is a three-sided polygon that consists of three edges and three vertices.

To determine whether the triangle formed by joining the straws will be a right triangle

we need to check if it satisfies the Pythagorean theorem

Let us assume that the 7.5-inch straw is the hypotenuse of the triangle. We need to check whether the sum of the squares of the other two sides (4.5 inches and 6 inches) is equal to the square of the hypotenuse (7.5 inches).

Using the Pythagorean theorem, we have:

7.5² = 4.5² + 6²

56.25 = 20.25 + 36

56.25 = 56.25

The sum of the squares of the two shorter sides is equal to the square of the longest side.

The triangle formed by joining the 4.5-inch, 6-inch, and 7.5-inch straws satisfies the Pythagorean theorem and is therefore a right triangle.

Hence, the measure 4.5 inches, 6 inches and 7.5 inches together form a triangle.

(X,y) (x-6, y+4)

The transformation rule for the new  ΔR'S'T' is  (x, y) →  (x - 6, y + 4). The correct option is (c).

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is f(x + a).

The given problem can be solved by using the rule of transformation as follows,

For the translation of 6 units left and 4 units up, it can be written as,

Suppose the coordinate of a vertex of ΔRST be given as (x, y).

Then, as per the rule the new coordinate of ΔR'S'T' is (x - 6, y + 4).

Hence, rule that best describes the transformation given in the problem is (x, y) →  (x - 6, y + 4).

Answer:

Answer:

[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

If I remember correctly, rate of change is basically slope.

So if you want, you can choose two points and use the slope formula. If you're lazy, or don't necessarily NEED to use the slope formula, then you can just choose two points and count the rise and run.

Slope = [tex]\frac{rise}{run}[/tex]

Rise = -2 (going down two)

Run = 3

Therefore the slope is:

[tex]-\frac{2}{3}[/tex]
