A. g(x) = 3x^2 + 6
If you are stretching vertically, that is along the Y axis. The original +2 is the y-intercept, so you add 4 onto the equation where the y (vertical) will be placed.
8/20 in simplest form is 2/5 because 8/20 divided by 4/4 equals 2/5
The equations are,
3x + y = 8 ——— 1
4x - 2y = 3 ——— 2
Multiply equation 1 by 2
Which gives,
6x + 2y = 16 ——— 3
Now , add equation 2 and equation 3
Which gives,
10x = 19
From there , x = 19/10
Therefore x = 1.9
Now substitute x = 1.9 in the equation 1
So the equation becomes ,
3*1.9 + y = 8
From that ,
y = 8 - 5.7
Therefore , y = 2.3
So , x = 1.9 and y = 2.3.
Okay?
Since 4 is half of the number 8, the simplest form of that would be 1/2
~1/2 is the same as 4/8
, so you get
