okay well first you should put it in slope-intercept form aka y = mx + b
but you have simplify everything first
2(x + 3) + 2(y + 2) = 16
2x + 3 + 2y + 4 = 16
2x + 2y + 7 = 16
-7 -7
2x + 2y = 9
-2x -2x
2y = -2x + 9
/2 /2
y = -x + 4.5
so now in a graph it should look like this:
The game has to be 12 because he plays 12 games and each day he plays for a long time
<span>ƒ(x) = 1/2x + 4
inverse
x = 1/2 y + 4
2x = y + 8
y = 2x - 8
so inverse f-1(x) = 2x - 8
</span>ƒ -1(4) = 2(4) - 8 = 0
answer
ƒ -1(x) = 2x - 8
ƒ -1(4) = 0
second one 12 5 because as you can see if you do the math divide it you get B
Answer:
D
Step-by-step explanation:
D should be your answer
