X = 8 would be ur equation and I dont believe u can write it in y = mx + b form because a vertical line has an undefined slope
Answer:
15 and 270
Step-by-step explanation:
Using the rule of radicals
× = a
![\sqrt[3]{a}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Ba%7D)
× × = a
(a)
Given
(
)² × (
)²
= 5 × 3
= 15
(b)
Given
(![\sqrt[3]{9}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B9%7D)
)³ × (
)²
= 9 × 30
= 270
Sum means add
5x+2x is at least 70
is at least means <u>></u>
so it is
5x+2x<u>></u>70
(5x+2x can be combined to get 7x and 7x<u>></u>70 divide 7 get x<u>></u>10)
