Solve for x.
x + 2 = -5
What is -7 >>>>>>>x + 2 = -5
x = -5 - 2
x = -7
100
The solution to the system of equations:
-2x + 5y = 7
2x - 5y = -7
What is infinitely many solutions
100
The point (2,3) after (x, y) becomes (x+2, y-3)
What is (4,0)
100
The slope of the line connecting (2,4) and (-2, -5)
What is 9/4
100
-4^2
What is -16 -42
-(4 2)
-(16)
-16
200
14 = -(x-8)
What is -6? 14 = -(x-8)
14 = -x + 8
6 = -x
so
x = 6

The solution to the system:
8x + 4y = -4
-10x + 4y = -4
What is (0,-1)
200
The parent function for linear equations.
What is y =x?
200
The equation with a slope of 3 and a y-intercept of 4
What is y = 3x + 4
200
4 + 32
What is 13
4 + 32
4 + 9
13
300
Solve for x. 3(x + 2) = 12
What is 2
300
The sum of two numbers is 104. Their difference is 68. What are the numbers?
What is 86 and 18
300
The coordinates of A are (2, 5). The coordinates of the point A' once A has been reflected over the x-axis.
What is (2, -5)
300
The x-intercept of 3x + 6y = 12
What is 4 or (4,0)
300
4 + 3^2 x 3 ÷ 3
What is 13 4 + 3^2 x 3 ÷ 3
4 + 9*3 /3
4 +27/3
4 + 9 >> 13
400
Solve for x.
2(4x -3) - 8 = 4 + 2x
What is 3? 2(4x -3) - 8 = 4 + 2x
8x - 6 - 8 = 4 + 2x >>> -2x both sides
6x = 4 + 6 + 8
6x = 18 >>>>>>>>>>/6 both sides
x = 3
400
The solution to the system of equations:
5x - y = 13
7x + 2y = 25
What is (3,2)
400
The equation when y = x is compressed by a factor of 1/2 and has a vertical translation down by a factor of 5.
What is y= 1/2x -5
400
The slope of the line
3y = 2x + 5
What is 2/3
400
What is 9/4
>> 1/(4/9) >> 9/4
500
Solve for x.
-(1+7x) - 6(-7-x) =36
What is 5 -(1+7x) - 6(-7-x) =36
-1 - 7x +42 + 6x = 36
-x = 36 + 1 - 42
-x = 5
500
The solution to the system of equations:
- 10 x + 2y = -7
2y + 8 = 10x
What is NO SOLUTION

If x= -2 and y = 4 then evaluate
3x2y + (-3x)
What is 54? 3x2y + (-3x)
3(-2)2 (4) + (-3*-2)
3(4)(4) + (6)
48 + 6 = 54
