Question

Help please

Answer 1

Answer:

Part A

Given function

• y = 5.3x + 23

The value of y at x = 6:

• y = 5.3*6 + 23 = 54.8° C

The closest choice is :

• B.  The water will be about 55⁰C

Part B

The y-intercept is the value of y when x = 0

• y = 5.3*0 + 23 = 23° C

This is the initial temperature at zero minute time, before heating is applied.

Correct choice is:

• D. 23; the temperature of the water before it is heated
