-2x+4=3
move the 4
-2x+4=3
-4 -4
-2x=-1
then you would move the -2 by using division
-2x=-1
__ __
-2 -2
x=0.5
The simple way to dilate from the origin is to multiply each coordinate by the dilation factor.
Example:
point A(2,-4) dilated by 2
A'(2*2, -4*2) = A'(4, -8)
Point A dilated by 1/2
A''(2*1/2, -4*1/2) = A''(1, -2)
If you have multiple points dilated by the same factor, then follow the procedure for ALL the points
Answer:
The lastt one
Step-by-step explanation:
16 gal... 480 mi
1 gal... 480/16 = 30 mi
9 gal.. 30*9 = 270 mi
If you would like to know who is correct, you can find this using the following step:
<span>6x - 2 = -4x + 2
Spencer:
</span>6x - 2 = -4x + 2 /+4x
6x - 2 + 4x = -4x + 2 + 4x
10x - 2 = 2
Jeremiah:
6x - 2 = -4x + 2 /-6x
6x - 2 - 6x = -4x + 2 - 6x
-2 = -10x + 2
They both are correct. But in Jeremiah's version of solving the equation, we would have to multiply equation by -1 (or add 10x to both sides), which we don't have to do in the Spencer's version.
