Determine whether the lines AB and CD would be parallel, perpendicular, or neither?
A(-5,3) and B(-5, 7)
What is the slope of AB?
C(1, 9) and D(-10, 9)
What is the slope of CD?
What are the lines? (parallel, perpendicular or neither)
Answer:
The slope of AB is undefined; the slope of CD is 0; The lines are perpendicular.
Step-by-step explanation:
Line AB would form a vertical line. Slope is Δy/Δx. To go from 3 to 7 (the y-coordinates) you need to go up 4 units. So we would then have Δy/Δx = 4/Δx. To go from -5 to -5 (the x-coordinates) we have to go left or right 0 units. So, Δy/Δx = 4/Δx = 4/0. Anything divided by 0 is undefined. Remember: vertical lines always have an undefined slope.
Line CD would form a horizontal line. To go from 9 to 9 (the y-coordinates) you need to go up or down 0 units. So, Δy/Δx = 0/Δx. To go from 1 to -10 (the x-coordinates) you need to go down 11 units. So Δy/Δx = 0/Δx = 0/1. 0 divided by anything is 0. Remember: horizontal lines always have a slope of 0.
If you picture a horizontal line and a vertical line intersecting, they would both form a right angle when they intersect. By definition, this would make both lines perpendicular.

1. Regular pay amount:
2. Overtime pay:
3. Gross pay:
Answer:
1. 700
2. $157.50
3. $857.50
Step-by-step explanation:
Regular pay is calculated by taking 40 hours x $17.50 to get $700.
Overtime is calculated by taking 6 hours x 17.50 x 1.50 to get $157.50
Gross pay would be adding these two amounts together.

A new club sent out 288 coupons to boost sales for next year's memberships. They provided 5 times as many to potential members than to existing members. How many coupons did they send to existing members?
A.
6
B.
5
C.
53
D.
48
Answer:
D. 48
Step-by-step explanation:
We don't know the numbers of coupons sent to existing members and to potential members, but we know a relationship between the number.
They sent 5 times as many coupons to potential members as they did to existing members.
Let x = number of coupons sent to existing members.
Then 5x = number of coupons sent to potential members.
The total number of coupons sent was x + 5x = 6x
The total number of coupons sent was 288.
Therefore, 6x must equal 288 giving us an equation with a single variable.
6x = 288
x = 48
Answer: 48
Nina works in as an office receptionist for $15.00 per hour. If her pay is increased to $18.00, then what is her percent increase in pay?
*If you solve this for me can you also put how you got to the answer? just so I can see how you did it :]
Answer:
20%
Step-by-step explanation:
the number is increased by 3 so you put 3 on 15 and 3/15=1/5=2/10=20/100
The percentage increase in the pay of Nina is 20%.
How to calculate percentage increase?To calculate the percentage increase work out the difference (reduction) between the two figures you are comparing before calculating a percentage drop. Then, increase the result by 100 after dividing the decrease by the initial number.
% Increase = Increase / Original Number × 100
Nina got the initial pay as $15.00 per hour.
After the increment, her pay increased to $18.00.
The total increment = final pay - initial pay
= 18.00 - 15.00
= 3.00
Now, the percentage increase = (3/15)×100
= 20
Therefore, there is the 20% increment for the pay of Nina.

You want to get new shoes they are 30.56 how much will the shoes be with 8% tax?
Answer:
Amount of sales tax ≈ $2.44 dollars;
Price with sales tax ≈ $33 dollars;
Step-by-step explanation:
1. Calculate the 'Amount of sales tax':
Formula:
Amount of sales tax =
Sales tax rate × Price without sales tax
Calculation:
Amount of sales tax =
8% × 30.56 =
8/100 × 30.56 =
8 ÷ 100 × 30.56 =
0.08 × 30.56 =
2.4448 ≈
2.44
(Rounded to a maximum of 2 decimals)
2. Calculate the 'Price with sales tax':
Formula:
Price with sales tax =
Price without sales tax + Amount of sales tax
Calculation:
Price with sales tax =
30.56 + 2.4448 =
33.0048 ≈
33
(Rounded to a maximum of 2 decimals)

7=3 over 4x what is x?
Answer:
x=28/3
Step-by-step explanation:
combine multiplied terms into a single fraction
7 = 3x/4
multiply all terms by the same value to eliminate fraction denominators
4 · 7 = 4 · 3x/4
cancel multiplied terms that are in the denominator
4 · 7 = 3x
multiply the numbers
28 = 3x
divide both sides of the equation by the same term
28/3 = 3x/3
simplify
a. cancel that are in numerator and denominator
28/3 = x
b. move the variable to the left
x = 28/3

The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that represents the situation?
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
It is linear because the function is continuous.
It is nonlinear because the final cost is determined by multiplying each price tag by 0.75.
It is nonlinear because the price tag and final cost columns do not have the same common difference.
Answer:
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant
Answer:
It's A. Edge 2022
Step-by-step explanation:
So basically, you just multiply 10, 20, 30, and 40 by 0.75
So now the numbers on your table are 7.5, 15, 22.5, and 30.
7.5 + 7.5 is 15, 15 + 7.5 is 22.5, and 22.5 + 7.5 is 30, so it's linear.

The sum of four consecutive integers is 134. Find the integers. (please show your work)
Answer:
Integers: 32,33,34,35
Step-by-step explanation:
Consecutive means back-to-back, with a difference of 1
Therefore this can be represented with the following equation (where x is the first number), and we can set this equal to the sum
[tex]x+(x+1)+(x+2)+(x+3)=134\\4x+6=134\\4x=128\\x=32[/tex]
Therefore since x = 32, all four integers are:
[tex]32,33,34,35[/tex]
If we check this, we can see that their sum equals to 134
[tex]32+33+34+35 = 134[/tex]
Hope this helps!
