Answer:
x = 20.
Step-by-step explanation:
-2x – 9x = -12(x +5) + 8(x – 10)
-2x – 9x = -12x -60 + 8x – 80
-2x - 9x + 12x - 8x = -140
-7x = -140
x = 20.
I’m pretty sure the answer is 155 but i do not know for sure
36.9. Just input the number in the equation and you get 4.5x18.2=36.9 as the volume
Your answer is √(x + 4).
A strange way to find the inverse of a function is to write it first as y = x² - 4, and then to switch the y and x around to get x = y² - 4. Then you just solve for y, so:
x = y² - 4
+ 4
x + 4 = y²
√
√(x + 4) = y
I hope this helps!
