Answer:

y = 2(x+5)²- 60

Step-by-step explanation:

f(x) = ax² +bx +c,  is the standard form

f(x) = a(x - h)² +k , is the vertex form where the (h, k) is the vertex

y = 2x²+20x -10 ,

factor 2 from the two terms

y = 2(x² +10x) -10,

what perfect square has x² +10x? ... x²+10x +25 = (x+5)²

y = 2(x²+10x+25 )- 50 -10,

add 25 in parenthesis to get a perfect square yet subtract 2*25 = 50 so the equation will stay the same

y = 2(x+5)²- 60,

the equation has the vertex at (-5, -60)

Solve for u
Sergio039 [100]
U/9 = 8/12 u = 6

Step 1: Cancel the common factor (4)

u = 2
—- —-
9 3


Step 2: multiply both sides by 9


9u 2 * 9
—- = ——-
9 3

Step 3: simplify

2 *9 = 18

18 ÷ 3 = 6

u = 6
