The graph represents function 1 and the equation represents function 2:

A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.

Function 2
y = 3x + 1

How much more is the rate of change of function 2 than the rate of change of function 1?

1
2
3
4

Answers

Answer:

Step-by-step explanation:

Rate of change of function 2 = y2-y1 / x2 - x1

If we use x1 = 0 and y1 = (3(0) + 1 = 1 and x2 = 4 and y2 = 13,

the rate of change = (13-1)/ (4-0) = 12/4 = 3.

The rate of change of function 1 is zero.

So the answer is 3-0 = 3.

Carrie missed 12% of the problems on Coach Blanc’s Texas History test. The test had a total of 125 problems. How many problems did Carrie get correct on the test?

DON'T JUST ANSWER FOR POINTS
I NEED THE ACTUAL ANSWER

Answers

Answer:

110 i think

just search 12% of 125 the subtract it from 125

Answer:

She missed 15 on it because 12 percent of 125 is 15, so that would mean she got 110 questions right on her test.

Step-by-step explanation:

125/x=100/12 (125/x)*x=(100/12)*x - we multiply both sides of the equation by x 125=8.33333333333*x - we divide both sides of the equation by (8.33333333333) to get x 125/8.33333333333=x 15=x x=15 now we have: 12% of 125=15

Answer:

#5 = option a (129.38 miles):

We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!

#2 = option a (2.4 inches)

We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!

#4 = ?

#6 = option c (7.2cm)

So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)

#3 = ?

Answer: A

Step-by-step explanation: 17.25/2=8.652

8.652*15=129...

rounded it would be equivalent to answer choice A.

What is 100% of 1,200 IF 1,200 is 50%
Brainliest will be given. Also no bots!

Answers

Sustitute the value of the variable inot the equation and simply and you get 0.5

Maybe 2,400 because since 1,200 is 50% you have to add another 50% to get the 100% of 1,200 so you just add 1,200 + 1,200 giving you 2,400
