Hello from MrBillDoesMath!
Answer: 21
Discussion:
g(3) = 3^2 -2 = 9 -2 = 7 =>
f(g(3)) = f (
7) = 2(7) + 7 = 14 + 7 = 21
Thank you,

Answer:
lol I'm not good at those
its step 2 he did not subtract it right hope this helps and have a great day and get some sleep lol
Hello there!
3x - y = 3
-x + y = 3
We need to solve 3x - y = 3 for y
Let start by adding -3x to both sides
3x - y = 3
3x - 3x - y = 3 - 3x
-y = 3 - 3x
We cannot leave the variable with a negative sign. We must multiply both sides by -1
-y * -1= (3 - 3x)-1
y = 3x - 3
Substitute 3x -3 for y in -x+y=3
-x + y = 3
-x + 3x - 3 = 3
2x - 3 = 3
2x = 3 + 3
2x = 6
x = 6/2
x = 3
Now substitute 3 for x in y=3x -3
y = 3x - 3
y = 3(3) - 3
y= 9 - 3
y= 6
Thus,
The answer is x=3 and y=6
It is always my pleasure to help students like you :)

Answer:
Move downward by 7 units
Move leftward by 6 units
Step-by-step explanation:
Given
See attachment for grid
Required
The transformation from the current location to the new location
To do this, we pick two corresponding points on the current location and the new location.
We have:
-- Current location
-- New location
First, move A downwards by 7 units.
The rule to this is:
So, we have:
Next, move the above points leftward by 6 units.
The rule to this is:
So, we have:
