the slope is 1/2. the equation would be y=1/2x

Answer:

5/2 or 2.5

Step-by-step explanation:

Slope formula:

(y₂ - y₁) / (x₂ - x₁)

Two points are given:

(2, 5) and (6, 15)

x₁ = 2

y₁ = 5

x₂ = 6

y₂ = 15

Your answer would be 46.50 because you would divide 31 in half (for the 50%) then add that to the 31. So 31+15.50= $46.50 hope this helps. If not let me know

What are the coordinates of R' after a dilation by a scale factor of 3, centered at the origin, followed by the translation (x, y) - (x, y + 3)?
A. (9, 8)
B. (12, 18)
C. (9, 18)
D. (9, 24)​

Answers

9514 1404 393

Answer:

  C.  (9, 18)

Step-by-step explanation:

Given R(3, 5), a dilation by a factor of 3 will multiply each coordinate to give ...

  (9, 15)

Then the translation up by 3 will give you the image coordinates ...

  (x, y) ⇒ (x, y+3)

  (9, 15) ⇒ (9, 15 +3) = (9, 18)

The coordinates of R' are (9, 18), matching choice C.

_____

Comment on multiple choice answers

As it often does, here it works to "guess" the answer that has the coordinates that are most-repeated. An x-coordinate of 9 is part of 3 answer choices; a y-coordinate of 18 is the only repeated value in the answer choices. If you were to guess, an appropriate guess would be (9, 18). That happens to be correct in this case.

Answer: C. (9,18)

Step-by-step explanation: I have had this question on a quiz before.

4. The length of a rectangle is eight more than
twice its width. The perimeter is 96 feet. Find
the dimensions of the rectangle.

Answers

Answer:

length = 104/3 ft

width = 40/3 ft

Step-by-step explanation:

Variables:

L = length

w = width

Set up equations:

L = 8 + 2w2L + 2w = 96

Substitute L with the first bullet point equation:

2L + 2w =  96

2(8 + 2w) + 2w = 96

16 + 4w + 2w = 96

16 + 6w = 96

6w = 80

w = 40/3 ft

Find L now that you have the value of the width:

L = 8 + 2w

L = 8 + 2(40/3)

L = 8 + 80/3

L = 104/3 ft

Final Values:

length = 104/3 ft

width = 40/3 ft

The ticket sales for a concert started at 4:00 P.M. The table shows the linear relationship between the number of tickets remaining and the number of hours since 4:00 P.M.

Which function can be used to find y, the number of tickets remaining x hours since 4:00 P.M.?

a
y = 3,000x + 12,000
b
y = -3,000x + 12,000
c
y = -3,000x + 15,000
d
y = 3,000x + 15,000

Answers

Answer:d

Step-by-step explanation:

The function which represents the number of tickets remaining after x hours is b. y = -3,000x + 12,000.

What is a function?

A function can be defined as the values of the inputs for which the output is defined. The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

From the given graph we can observe that every hour 3000 tickets were sold.

Assuming hours to be x and tickets remaining at any time is represented

by y and as the tickets were sold we can denote it with a negative sign.

∴ The function which represents the number of tickets remaining after x hours is,

y = -3000x + 12000.

To check whether our function is correct or not we can put any value of x from 1 to 4 in our function.

Find the slope and y-intercept.

Answers

Answer:

y-intercept = -5, slope = 5/3

Step-by-step explanation:

The y-intercept is where on the y-axis (vertical line) does the graph cross. The slope can be found many different ways. My method for this graph was simply counting up the graph until I got to the point where the graph crosses another whole number on the x-axis and then counted over. This makes sense because slope is rise over run so if you go up 5 (from the y-intercept) and then over 3 (to get to the next whole number point) then your slope is 5/3

So if the regular price of an item is 25 and the store is marking it up by 40%, then we have to multiply 25 by .4 to find out what 40% of 25 dollars is. 40% of 25 is 10 dollars. So now you just do 25 + 10 and you get 35. Answer: $35
