Consumer Reports tested 19 different brands and models of bikes. Road bikes are designed for long trips and fitness bikes are designed for daily commutes and regular workouts. Data available for this set of bikes is comprised of weight of the bike (in pounds) and its price (in $). You are hired as a statistician to analyze how much of the weight and the type of bike characteristics determine its price.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
