Which system of equations is graphed below?
x-y=6, 4x+3y=1
x-y=6, 3x+4y=4
x+y=6, 4x-3y=3
x+y=6, 3x-4y=4
(Pls give brainliest! :D)
Answer:
B
Step-by-step explanation:
You know that the graph intercepts at the point of (4,-2)
Where x = 4 and y = -2.
This means that whenever you plug a value of x in the equation it should give the value of y.
For example when you plug x= 4 into the equation (B), it should look like this.
4- y = 6, solving for y gives us the value negative 2.
This means that it does give us this point, however, as the graph shows us, both lines meet at the point which means that both equation should give us this point.
If we substitute x = 4 in the second equation of b, we should be able to get 3(4) + 4y = 4. Solving for y gives us -2.
Hope this helps!

*SPAM ANSWERS WILL NOT BE TOLERATED*
Answer:
A = 45 degrees
Step-by-step explanation:
PS AND PQ IS THE SAME,
which means that each side is the same,(left and right)
a triangle, has 180 degrees
180-90
=90
90/2(get the angle of each sides that are left)
=45 degrees is the answer
Now pay up 100 points, lol
Answer:
The measure of angle a is 45 degrees.
Step-by-step explanation:
Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:
90 + a + a = 180
2a = 180 - 90 = 90
a = 90/2 = 45
a = 45

Julie says the most amount of time spent homework is 1 1/2 times the least amount of time spent on homework. Is she correct? Explain.
Daniel says that more than half the students spent 2 1/2 hours or more on homework. Liz says more than half the students spent less 2 1/2 hours on homework. Who is correct? Explain.
From the values in the statistical data we have;
The most amount of time spent is [tex]3\frac{3}{4}[/tex] the least amount of time, Julie is incorrectLiz is correct because 7 out of 12 students spend less than [tex]2\frac{1}{2}[/tex] on homeworkHow can the given statements be evaluated?The possible given data in question, are as follows;
[tex]\begin{array}{cccc}1\frac{3}{4} &2\frac{1}{2} &2&2\frac{3}{4} \\\\1&1\frac{3}{4} &1\frac{1}{4} &3\\\\3\frac{1}{4} &3\frac{3}{4} &2&2\end{array}\right][/tex]
From the data, we have;
The most amount of time spent = [tex]3\frac{3}{4}[/tex]
The least amount of time spent = 1
Therefore;
The most amount of time is [tex]3\frac{3}{4} \times 1[/tex] = [tex]3\frac{3}{4}[/tex] times the least amount of time
Julie is incorrectSecond part;
The number of students that spent less than [tex]2\frac{1}{2}[/tex] = 7
The number of students that spent [tex]2\frac{1}{2}[/tex] or more = 5
The number of students in the survey = 12

Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain how you found them.
To find those equations we can do any multiplication or division of both sides of the equation:
Examples:
2x + 9 = -15 | · 2
4x + 18 = -30
2x + 9 = -15 | · (-1)
-2x - 9 = 15
2x + 9 = -15 | ÷ 2
x + 4.5 = -7.5
There is the same solution: x = -12.
The three different equations (x = -12, 2x = -24, and -2x - 9 = 15) that have the same solution as the original equation 2x + 9 = -15.
To find three different equations that have the same solution as 2x + 9 = -15, we can manipulate the given equation using algebraic operations. The goal is to preserve the solution while changing the form of the equation. Here are three different equations:
Subtract 9 from both sides of the equation:
2x + 9 - 9 = -15 - 9
2x = -24
Divide both sides of the equation by 2:
(2x)/2 = (-24)/2
x = -12
This equation, x = -12, has the same solution as 2x + 9 = -15.
Multiply both sides of the equation by -1:
-1(2x + 9) = -1(-15)
-2x - 9 = 15
This equation, -2x - 9 = 15, has the same solution as 2x + 9 = -15.
By applying these transformations, we obtained three different equations (x = -12, 2x = -24, and -2x - 9 = 15) that have the same solution as the original equation 2x + 9 = -15.

Before the baseball season begins, a field manager outlines the "on-deck" circle with chalk and covers the area with dirt.
If the "on-deck" circle has a diameter of 6 feet, about how long is the chalk outline?
Answer:
C maybe
Step-by-step explanation:
The field is circular and the line drawn by chalk is length of the rim of the circular field, and is called circumference. It can be calculated from radius(or diameter) of the circle.
The length of the chalk outline is given by:
Option A: 19 feet.
Given that:The field given is circular in shape.The circular field has diameter of 6 feet.To find:The length of the chalk outline.
Formula for circumference of a circle:[tex]|Circumference| = 2 \times \pi \times r = \pi \times d[/tex]
where r represents the radius of the circle and d represents the diameter of the circle.
The diameter d = 2 times r always. (diameter is twice of length of radius)
Thus, we have:
[tex]\text{Length of chalk line} = \pi \times d = \pi \times 6 \approx 18.84 \approx 19 \rm \: feet[/tex]
The length of the chalk outline is given by:
Option A: 19 feet.

Represent the expression as a decimal number.
Answer:
Step-by-step explanation:
The area of a circle is represented by the equation A=πr2, where r is the radius. The area is 64π m2.
What is the length of the diameter?
The length of the diameter is 16 cm.
What is Area of Circle?The area of a circle is pi times the radius squared.
i.e., Area of Circle = πr².
Given:
Area = 64π m²
Now, Area of Circle= πr²
64π = πr²
64 = r²
r= √64
r= 8 cm
