A line with a slope of –4 passes through the points (9,w) and (8,9). What is the value of w?

Answers

Answer 1

Answer:

5

Step-by-step explanation:

A slope of -4 means that for every x increase by 1, the y decreases by 4. so going from (8,9) to (9,w), w should be 9-4, which is 5

Hello! :)

We can use the slope formula:

[tex]\frac{y2-y1}{x2-x1} \\\frac{1-7}{-5-(-5)} \\\frac{-6}{-5+5} \\\frac{-6}{0} \\[/tex]

The slope is undefined. Here's something you should remember:

If the x-coordinates are the same, then the slope is undefined.

1)Solve 3x+2= 5
A. Model 3 2 x+ = 5.
B. Perform the step to have the variables (circles) alone on one side.
C. Write the resulting step.
D. Divide the variables (circles) and numbers (squares) into equal groups.
E. Show the value of one group.

Answers

The value of x in the equation, 3x + 2 = 5 is 1.

In order to solve this equation: 3x + 2 = 5, take the following steps:

Combine similar terms together:

3x = 5 - 2

Add the similar terms together

3x = 3

Divide both sides of the equation by 3 in order to make x the subject f the formula

3x / 3 = 3 /3

x = 1

55.99 dollars gift with 18% coupon and 7.25% sales tax. What is the final cost?

Answers

Answer:

I think it is $91.89.

Step-by-step explanation:

1. Take the number and add sales tax by multiplying 0.0725 ( since that is what the percentage is in a decimal form). Then add that to the original and you have what it would be plus sales tax: $60.05.

2. Then you would need to multiply by 0.18. You would get 10.809

3. Next, subtract the 10.809 from $60.05 and the answer is $49.24.

I hope this helps! :)

7x – 10y = 3. Is this a good model? Explain your reasoning.

Answers

Answer:

No. Correct is 7x - 10y = 6.

Step-by-step explanation:

The slope of the line is (-9-5)/(-12-8) = 7/10

y - 5 = 7/10(x - 8)

10y - 50 = 7(x - 8)

10y - 50 = 7x - 56

7x - 10y = -50 + 56

7x - 10y = 6.

Answer:  No, it's not a good model

Explanation:

Let's plug in x = 8 and y = 5. This is directly from the ordered pair (8,5).

7x - 10y = 3

7*8 - 10*5 = 3

56 - 50 = 3

6 = 3

We get a false equation at the end, which means the original equation is false when (x,y) = (8,5). Therefore, the point (8,5) is not on the line 7x-10y = 3. Furthermore it means that 7x-10y = 3 is not a good model since Devon wanted the line to pass through both given points.

If you were to plug in (x,y) = (-12,-9), then you would find the same thing happens. For each ordered pair, the left side results in 6. So if Devon were to change that "3" to "6", then it would be a good model as both points would be on the line. In other words, the standard form equation Devon should use is 7x-10y = 6. When solving for y, Devon would get y = (-7/10)x - 3/5

Below is visual confirmation that 7x-10y = 3 is not a good model. Both points are not on the line. The graph was made using GeoGebra.

Answers

Answer:

Step-by-step explanation:

0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056

In the Diagram below DE≅AE ,BA∥CE

and m∠C=65∘

Find m∠BAE

Answers

Answer:

∠ DAE = 130°

Step-by-step explanation:

ABCD is a parallelogram ( opposite sides are parallel )

The opposite angles of a parallelogram are congruent , then

∠ BAD = ∠ BCD = 65°

∠ ADE = ∠ BAD = 65° ( alternate angles )

Since DE = AE then Δ ADE is isosceles with 2 base angles congruent, that is

∠ DAE = ∠ ADE = 65°

Then

∠ BAE = ∠ BAD + ∠ DAE = 65° + 65° = 130°

The cost of admission to a festival was $112 for 9 children and 3 adults. The admission was $108 for 8 children and 3 adults in another festival. How much was the admission for each child and adult?

Answers

Answer:

cost of admission for each child was $4.00, and each adult was $25.33

Step-by-step explanation:

When solving questions like these , I like to break down the problem so I understand it better.

Let x ---> cost of the admission for each child

Y ---------> cost of the admission for each adult

9x+3y = 112 ---> equation A

8x + 3y = 108 ---> equation B

Subtract B from A

9x+3y=112

-8x+3y = 108

x = 112-108

x = 4

Find value of y by substituting value of x into equation

9(4)+3y=112

Solve for y

36+3y = 112

3y = 112=36

3y = 76

y = 25.33
