Start by dividing with a calculator.
Subtract 
, since it represents the cost of a mat.
Move the decimal two places to the right to convert to a percentage.
Answer:
B=-6
Step-by-step explanation:
-21+9=-12
-12/2=-6
You can check it.
The inverse of a function is the reflection of it across the line y=x. If (2, 8) is on the graph of g(x), then (8, 2) is on the graph of its inverse. If the slope of g(2) is 5, then the slope of (g^-1)(8) is 1/5, the reciprocal of g'(2).
... (g^-1)(8) = 1/5
If A,B and C lie on the same line:
4x- 9 + 3x+5 = 17
7x = 21
x = 3
Answer:
I am 90% sure that the answer is M'N'O' is 90*
Step-by-step explanation:
A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?
