Answer:
u as the subject of the given formula is, 
Step-by-step explanation:
Given;
v² = u²+2as
To make u the subject of the formula, the following steps are taken;
v² = u²+2as
v² - 2as = u²
take the square - root of both sides of the equation;

Thus, u as the subject of the given formula is, 
To write the problem out as an equation, let 'n' equal your number.
(15 x 1/n) - 3n
Rise = 8
Run = 1
Slope = 8
He had $5,000,000 in CD sales; $3,300,000 in video sales; and he earned $1,245,000 in royalties.
1,000,000 CDs * $5 each = $5,000,000
550,000 videos * $6 each = $3,300,000
Total sales = 5,000,000+3,300,000 = 8,300,000
15% royalties = 0.15(8,300,000) = 1,245,000
