If point D' is the image of D(-2,1) under a reflection across the x-axis. What are the coordinates of D'?

Answers

Answer:

(-2, -1)

Answers

I think the answer is P=3
Simplifying
8p + -4p = 2p + 6

Combine like terms: 8p + -4p = 4p
4p = 2p + 6

Reorder the terms:
4p = 6 + 2p

Solving
4p = 6 + 2p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-2p' to each side of the equation.
4p + -2p = 6 + 2p + -2p

Combine like terms: 4p + -2p = 2p
2p = 6 + 2p + -2p

Combine like terms: 2p + -2p = 0
2p = 6 + 0
2p = 6

Divide each side by '2'.
p = 3

Simplifying
p = 3

John made $200 this month mowing lawns.
Ashley had a yard sale and made 74% of what John
made. Chris received birthday money in an amount that
was of what Ashley made. How much birthday money
did Chris receive?

Answers

Answer:

B: $74

Step-by-step explanation:

To find out how much Ashley made, you need to find how much 74% is of 200. The answer to this is 148. Since Chris made 1/2 of what Ashley did, we have to divide 148 by 2. And you get 74

A carpenter has a wooden plank that is 1 m long, 12 cm wide and 4 cm thick. The LENGTH : WIDTH : THICKNESS ratio of the plank is
A 1:12:4
B 1:3:1
C 25:3:1
D 25:12:1

Answers

The answer is C.

Explanation:

You have to first turn the meter(s) into centimeters like the rest.
(They all MUST be the same type)
1m = 100cm

Now you have to simply the amounts.
Since we can divid all of the numbers by 4, we will simplify by 4.

100 / 4 = 25
12 / 3 = 4
4 / 4 = 1

Therefore your answer is C.

25, 4, 1

The solution is Option A

The ratio of length : width : thickness of the plank is 1 : 12 : 4

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the length of the plank = 1 cm

The width of the plank = 12 cm

The thickness of the plank = 4 cm

Now , the proportion is given as

The ratio of length : width : thickness of the plank = 1 : 12 : 4

Therefore , the value of A is 1 : 12 : 4

Hence , the proportion is  1 : 12 : 4

Hey guys...I really need help on this... Compare the original figure to the enlarged figure. Which ratios can be used to find the scale factor? Check all that apply.
Please don't copy google or others websites...
I'm giving out more points again...

Answers

Answer:

A and C.

Step-by-step explanation:

Remember that to find the scale factor, we can write a ratio between each of the corresponding sides.

In other words, the scale factor k will be:

[tex]k=\frac{\text{Enlarged Side}}{\text{Corresponding Original Side}}[/tex]

Most importantly, their sides must be corresponding.

So, let's go through each of the answer choices.

A)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{6.5}{3.25}[/tex]

In our figures, we can see that 6.5 from our scaled figure indeed corresponds to 3.25 from our original figure. So, A is correct.

B)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{3.25}{6.5}[/tex]

This is not correct because 3.25 is our original, not our enlarged. It should be flipped, like choice A. So, B is not correct.

C)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{3}{1.5}[/tex]

We can see that 3 from our enlarged figure indeed corresponds with 1.5 from our original figure. So, choice C is also correct.

D)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{1.5}{3}[/tex]

Similarly to B, this is not correct because our enlarged number should be in the numerator while our original number should be in the denominator. So, D is not correct.

E)

We have:

[tex]k=\frac{\text{Enlarged}}{\text{Original}}=\frac{1.5}{3.25}[/tex]

This is not correct because the sides do not represent the scaled figure. Both of the given side lengths are from the original figure, and so we cannot determine the scale factor from this.

So, our final answers are A and C.

And we're done!

A and C

Then, we can add 3x to both sides:

5x - 11 = -13
