In order to find which one is or isn't, you need to solve for the value of 'x'.
2x + 15 = 35
2x = 20
x = 10
Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,
Answer is B
Double check this. Chur! :)
Hope this makes sense.

Answer:
y= -1*x +12
Step-by-step explanation:
x=4 is a function that always has the value 4 for the x-axis, no matter y variable, this a vertical function.
Perpendicular Lines are those with the following condition:
y=a*x+b (1)
y=c*x+d (2)
Where a and c are the respective slope
If These two lines are perpendicular, then
a=- 1/c
Using those principles we have that the slope for our needed line has to be -1, since the slope for the first line is 1 (the coefficient of x is 1, in the line x=4)
Lets use the given point (5,7) in the equation (2)
7=-1 * 5 + d
resulting d=12
so, our equation for the line is y= -1*x +12
Answer:
24
Step-by-step explanation:
the area of the triangle is 4 x 2, which equals 8.
Then you calculate the area of the rectangle.
Area of Rectangle = L x W or (in this case) 8 x 4
8 x 4 = 32
Then you subtract the area of the triangle from the area of the rectangle
So, your equation would be 32 - 8 = 24
Therefore, the area of the shape is 24
