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, point, 5, degree celsius per minute, and it reached the desired temperature of 80, degree celsius after 12 minutes. graph the pizza's temperature (in degrees celsius) as a function of time (in minutes).

For this case, what we are going to do is write a linear equation of the form:

 T = 7.5 * x -10

 Where.

 7.5: heating speed of the pizza.

 -10: initial temperature.

 x: time in minutes.

 For x = 12 we have:

 T = 7.5 * (12) -10

 T = 90-10

 T = 80

 Therefore the equation is correct.

 T = 7.5 * x -10

 See attached image.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
