Answer:

Slope is 4.

Step-by-step explanation:

To find the slope, you can use ¨y=mx+b¨ where m= slope, and b= y intercept.

Hope this helped!

Answer:

m=2

Step-by-step explanation:

4x−2y=5

Rewrite in slope-intercept form.

y=2x-5/2

Using the slope-intercept form, the slope is 2.

Movie tickets now cost seven dollars for adults over six years old. They cost six dollars a couple of years ago. What was the percent of increase?

Answers

Answer:

i think 3%

Step-by-step explanation:

Percent increase = (new value - initial value) / initial value
In this case, the new value is seven dollars, and the initial value is six dollars
So 7-6= 1. Divide by 6 will give u 0.16. The percentage increase is calculated by multiplying the answer by 100. So 0.16*100 = 16%. So 16% is the percentage increase.
In order to verify our answer. We find 16% of 6 and add it to 6. So 6 + 0.96 = 6.96 -> 7. So we are correct

-48=24

Find the intercepts of the graph given the following equation 4x – 3y = 12

Answers

Answer:

y-intercept: -4 or (0, -4)

x-intercept: 3 or (3, 0)

Step-by-step explanation:

4x - 3y = 12

we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept

4x - 3y = 12

-3y = -4x + 12

y = 4/3x - 4

So the intercept is -4 or (0, -4).

For the x-intercept, we can make the y value 0 to solve for x.

4x - 3y = 12

4x - 3(0) = 12

4x = 12

x = 3

So the x-intercept is 3 or (3, 0).

Find the measure of x in each figure. (Look at photo)​

Answers

Answer:

x = 20

Step-by-step explanation:

these angles are supplementary, which means they add up to 180°

using this, you can make the following equation:

6x + 60 = 180

subtract 60 from both sides of the equation

6x + 60 - 60 = 180 - 60

6x = 120

divide both sides of the equation by 6

6x/6 = 120/6

x = 20

identify the zeros of f(x) = (x + 9)(x − 4)(6x + 1).

Answers

Answer:

x = - 9, x = - [tex]\frac{1}{6}[/tex], x = 4

Step-by-step explanation:

To obtain the zeros, equate f(x) to zero, that is

(x + 9)(x - 4)(6x + 1) = 0

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 4 = 0 ⇒ x = 4

6x + 1 = 0 ⇒ 6x = - 1 ⇒ x = - [tex]\frac{1}{6}[/tex]

GIVING BRAINLIEST!!! PRETTY SIMPLE QUESTION!!!

Mei subscribed to a magazine at a rate of $24 for 12 issues. When she placed her order, Mei used a coupon that added 3 free bonus issues to her subscription. How did the coupon impact the cost per issue of Mei’s subscription?

O The coupon lowered the cost per issue by $0.40.
O The coupon lowered the cost per issue by $1.38.
O The coupon raised the cost per issue by $0.13.
O The coupon raised the cost per issue by $0.67.

Answers

Answer:

A

Step-by-step explanation:

Originally, Mei pays $24 for 12 issues.

Therefore, the cost per issue is:

[tex]c=\frac{\$24}{12\text{ issue}}=\$2\text{ per issue}[/tex]

With the coupon, Mei pays the same amount of $24 but for 15 issues.

So, the cost per issue now is:

[tex]c=\frac{\$24}{15\text{ issues}}=\$1.60\text{ per issue}[/tex]

Therefore, the coupon lowered the price of the issue by $0.40.

Our answer is A.

Answer: The coupon lowered the cost per issue by $0.40.

Original price of issue: $2

24 ÷ 12 = 2

Mei added 3 more issues, but she still pays $24.

The answer is A.

Two trains are traveling at constant speeds on different tracks.

Answers

Answer:

Train B is traveling faster

Step-by-step explanation:

From the picture, we want to know which train is traveling faster

We can know this by knowing the speed of the trains

Mathematically;

speed = distance/time

Train A

12.5 m in 1 second

speed = 12.5/1 = 12.5 m/s

Train B

100 m in 4 seconds

speed = 100/4 = 25 m/s

So train B is traveling faster

This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m

in 1 second
