Which linear relationship is modeled by the cost function f(x)=8x+3, with x representing the number of hours? 1. The cost of renting a bicycle is $8 per hour plus $3 for metal helmet

2.the cost of renting a bicycle is $8 plus for the helmet rental.

3.the cost is $11

4.the cost of renting a bicycle is $8 for helmet rental plus $3 per hour.

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

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

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

answer: none of these answers are correct only the second half is
