Answer: Choice D) 
================================================
Work Shown:

Explanation:
First I subtracted y/b from both sides. Then I multiplied both sides by 'a' to fully isolate x. You can optionally distribute the 'a' through to each term inside the parenthesis, but your teacher has chosen not to do this.
Answer:
Volume of the cube = (2n6)³
Step-by-step explanation:
Volume of a cube = L*B*H
Volume of a cube= L*L*L=L³ (since all the sides of the cube are equal.
Volume of the cube = (2n6)³
To subtract? as minus means subract/take away?
To properly visualize the given, we transform them into equation form rather than words.
f(x) = sqrt (x)
g(x) = 8(sqrt(x))
From these, it may be observed that g(x) is 8 times of f(x). These transformation is in the value of y and is scaling. Because it is multiplied by a a whole number, the transformation is vertical scaling that involves multiplying the y-coordinate by 8.
52 ×.65= X
The answer would be $80. Hope i could be helpful :)
