I hope this helps you
-7.x^3=2.7.9
x^3=-18
x=i.(3square root of 18)
A. 6 because 30/5= 6
B. She has gotten 35 points because 7*5=35
y = 8
using the ' gradient formula' m = (y₂ - y₁)/(x₂ - x₁)
with (x₁, y₁) = (3, 3), (x₂, y₂) = (- 5, y) and m = - 
(y - 3)/( - 5 - 3) = - 
(y - 3)/(-8) = - 
multiply both sides by - 8 to eliminate fractions
y - 3 = 5
add 3 to both sides
y = 5 + 3 =8
Answer: B
Step-by-step explanation: 7/8 * 3 = 2 5/8 :)
