Equation: 15 + 6t = 81
Work: 15 + 6t = 81
-15 -15
6t = 66
t = 11
slope =(y2-y1)/(x2-x1)
m=(-1-5)/(1--1)
m=-6/2
m=-3
y-y1=m(x-x1) point slope form
y-5 = -3 (x--1)
y-5 = -3 (x+1)
distribute
y-5 = -3x -3
add 5 to each side
y = -3x+2
Choice D
5400 = -3 8850-5100=3750m 1c = 100m
5300 = -2 3750/100 =37.5
5200 = -1
5100 = 0
answer = 37.5 degrees C
Answer:

Domain: All real numbers

Domain: x≠2
Step-by-step explanation:
The given functions are

and


This implies that:

We expand to get:

We expand to get:

We group like terms to get:

This is a polynomial function, the domain is all real.
Also;


Factor to get:

Cancel common factors:

The domain is all real numbers, except numbers that will make the denominator zero.
