Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y =
( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ =
( take the cube root of both sides )
x = ![\sqrt[3]{\frac{19}{y} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7By%7D%20%7D)
Change y back into terms of x, then
(x) =
=
→ A

The Value of the Expression
a. 50 times the sum of 64 and 36
... 50 x (64+36) = 50x (100) = 5000
50 x 64 + 36 )
5000
b. Divide the difference between 1,200 and 700 by 5
...(1200-700) / 5 = 500/5 = 100
(1,200 - 700): 5
100

...
+
=
= 
45 + 255
d. 15 times the sum of 14 and 6
... 15 x (14 + 6) = 15 (20) = 300
e.
10 x (250 +45)
...10 times the sum of 250 and 45
f.
(560 + 440) x 14... 14 times the sum of 560 and 440
