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)

Answers

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.

Pls help rn need finished within next 10 mins have to get right I’ll give 100 points

Answers

Answer:

100 points cool the answer is 30

the correct answer is first,fifth,sixth
x² -6x+2=0
a=1 a>0 so it has minimum value/point
since it is quadratic equation, hence the extreme value is at minimum point which is (3,-7)
in order to get that differentiate x²-6x+2
2x-6=0
2x=6
x=3

subtitude x=3 into the original equation
(3)²-6(3)+2
9-18+2
-7

extreme point (3,-7)

in order to know whether it is the solution of the equation or try subtitude it into the equation

(-3+√7)² -6(-3+√7)+2≠0
36-12√7≠0

(-3-√7)² -6(-3-√7)+2≠0
36+12√7≠0

(3+√7)² -6(3+√7)+2=0
(3-√7)² -6(3-√7)+2=0

hence the solutions are 3+√7 and 3-√7

The sum of four consecutive integers is 134. Find the integers. (please show your work)

Answers

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]

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.

Answers

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.

A.
6
B.
5
C.
53
D.
48

Answers

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

The formula used to solve all three is the pythagorean theorem, aka:
a^2 + b^2 = c^2

a = one of the sides, not hypotenuse
b = the other side, not hypotenuse
c = the hypotenuse (longest side)

9) We need to rearrange the equation, as x is looking for a side other than the hypotenuse. The rearranged formula would be:
a = √(c^2 - b^2)

One of the sides, b, is given as 22. The hypotenuse, c, is given as 37. Plug these numbers into the formula and solve.
a = √(37^2 - 22^2)
a = √(1368 - 484)
a = √884
a = 29.73

x = 29.73

10) Use the same rearranged formula, solving the same way
11) Use the original (not rearranged formula) and solve for the hypotenuse

7=3 over 4x what is x?

Answers

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

You want to get new shoes they are 30.56 how much will the shoes be with 8% tax?

Answers

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 =

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 :]​

Answers

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.
