Suraj took a slice of pizza from the freezer and put it in the oven. The oven heated the pizza at a rate of 7. 5 delicious, 5, degrees Celsius per minute, and it reached the desired temperature of 8 0 ∘ 80 ∘ 80, degrees Celsius after 12 1212 minutes. Graph the relationship between the pizza's temperature (in degrees Celsius) and time (in minutes).

40 minutes

step-by-step explanation:

add the time and multiply by 2

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

alright well the answers to your question is
