The graph of the equation is attached .

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

The slope-intercept form of the line equation

y= mx + c

where m is the slope

b is the y-intercept

We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation

y=47x .

Now comparing with the slope-intercept form of the line equation;

m = 47

We know that the value of the y-intercept can be determined by setting x = 0

substitute x = 0 in the equation

y = 47(0)

y = 0

Thus, the y-intercept b = 1

Thus,

The slope m = 47

The y-intercept b = 1

The graph of the equation is also attached.

(1,47) (2,94) (3,141)

Hence, the line passes through the origin with the y-intercept 0.

A store is having a 20% off sale on all merchandise. If Mai buys one item and saves $13, what was the original price of her purchase? Explain or show your reasoning.

Answers

Answer:

Step-by-step explanation:

If a store is having a 20% off sale

By buying an item you save 20% of the price

If Mai saves $13 on an item she is also saving 20%

$13 = 20% of the price

$65 = 100% of the original price

$65 is your answer!

Answer:

The Answer is $65! The orignal price of the item $65 because if you save $13 on a 20% off sale it would make the orignal price $65

−15x−40=23−8x
What does x =

Answers

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x  

Add 8x to both sides

-15x + 8x - 40 = 23

          -7x - 40 = 23

Add 40 to both sides

                - 7x = 23 + 40

                  -7x = 63

 Divide both sides by (-7)

            x = 63/-7

x = -9

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x

add 8x to both sides to bring -8x to the left side

-15x + 8x - 40 = 23

add 40 to both sides to bring -40 to the right side

-15x + 8x = 23 + 40

add the common terms

-7x = 63

for x to be alone divide -7 to both sides

x = -9

B.

Cindy. She has made 132 pizzas after 9 days.
C.

Paul. He has made 60 pizzas after 9 days.
D.

Cindy. She has made 48 pizzas after 9 days.

Answers

Answer:

c

Step-by-step explanation:

Paul made 60 pizzas after 9 days because he made 12 pizzas in the first day so 8 days is left and if you multiply 6×8=48 and you add the 12 pizzas of the first day you get 60.

6×8+12=60

What value of w makes the equation 145 = w + 27 true?

Answers

Answer:

118

Step-by-step explanation:

In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.

Answer:

118

Step-by-step explanation:

145 = w + 27

Switch the + sign before the 27 and switch into a minus and move it to the other side.

145-27=w

145-27=118

w=118

Hector runs laps around the track. The table shows how long it takes him to run different numbers of laps. How long would it take Hector to run 7 laps?
A.35 minutes

B.25 minutes

C. 15 minutes

D. 45 minutes

Answers

It would take him 35 minutes bro! Why? Because it’s in between the 40 and 30 from 6-8 laps. The answer is A
We can make a fraction to find out how many minutes for 1 lap. Let’s use the first ratio: 2/10 We can simplify that to: 1/5 So one lap for every 5 minutes, then we can multiply that for 7 laps: 5•7=35 So 35 minutes. The answer is A

Step-by-step explanation:

1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis

3x-12 = 5x + 10

2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)

2x = -22

3. Divide both sides by 2

x = -11

please give me brainliest if this helped

Answer:

x=−11

Step-by-step explanation:

3(x-4)=5(x+2)

Simplify both sides of the equation:

3(x−4)=5(x+2)

(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)

3x−12=5x+10

Subtract 5x from both sides

−2x−12=10

add 12 to both sides

−2x=22

Divide by -2 both sides

x=−11
