Answer:

This is true

Step-by-step explanation:

Say a= 3 and b=2

3 - 2= 1

(-2) + 3 = 1

An other example: say a=6 and b=8

6 - 8= -2

(-8) + 6= -2

PLEASE HELP THIS IS TIMED!!!! I WILL GIVE BRAINLIESTTTTTT
jekas [21]

Answer

Given: Sorry the images are at the bottom.

To find:

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).

Part B: Which function has a greater y-intercept? Justify your answer.

Solution:

On inspection of values of x and f(x) it is clear that f(x) is a linear function

i.e.

1)Slope of f(x) and y-intercept of f(x):

Convert the function in slope intercept form and calculate the slope.

Slope intercept form:

Here,

Slope of f(x)=1,

y-intercept of f(x)=(0,0)

2) Slope and y-intercept of g(x):

Slope of g(x)=7

Y-INTERCEPT of g(x) =(0,2)

Part A:

Slope of f(x) is 1 and slope of g(x) is 7.

Part B:

g(x) has a greater y-intercept.

Hope it helps you.

150 + 10t = 25t

150 = 25t - 10t

150 = 15t

150/15 = t

10 = t
