1. 12.12⋅(−2.9) 2. (−2.01)(7.3)

3. A section of road covers 18.3 square feet. Each square foot will require 5.1 minutes to repair.

How many total minutes will it take to repair this section of road?

4. (−3.2)⋅1.7

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
