Explanation:

Preimage = A = (10, 15)

Image = A' = (4, 6)

Divide the x coordinates of the image over preimage

4/10 = 0.4 is the scale factor

Or you could do the same for the y coordinates

6/15 = 0.4

Answer:

40%

Step-by-step explanation:

To find the percentage difference between the families with 2 dogs and the families with no dogs, we need to find their difference first.

Difference = 45 - 27

                  = 18

Now that we know the difference, we just have to put the difference over the total as a fraction and multiply by 100%.

Percentage difference = [tex]\frac{18}{45}[/tex] × 100%

                                      = 40%

The equation that represents the cost of each bag of apples is 5x + 4.36 = 24.26 and the cost is $3.98.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Isaac buys eggs and apples at the store. He pays a total of $24.26. He pays a total of $4.36 for the eggs. He buys 5 bags of apples that each cost the same amount.

Let x be the cost of each bag of apples. Then the equation is given as,

5x + 4.36 = 24.26

Simplify the equation, then we have

5x = 24.26 - 4.36

5x = 19.90

x = 19.90 / 5

x = $3.98

The equation that represents the cost of each bag of apples is 5x + 4.36 = 24.26 and the cost is $3.98.

Answer: D) Janelle can type 1/4 of a page in 2/3 of a minute

Step-by-step explanation:

Option A is wrong because based on the constraints, Janine would type less than 3/8 of a page in anything less than a minute. 8 > 3/8.

For that same reason, option B is wrong as well. 2 > 3/8.

1/2 > 3/8 so Option C is wrong for the same reason as the options above.

To test option D;

If Janine can type 3/8 of a page per minute, how much can she type in 2/3 minutes.

Assume the much she can type is x;

3/8 : 1

x    : 2/3

1x = 3/8 * 2/3

x = 1/4

Option D is therefore correct.

The answer is the second choice.

There cannot be repetitive domains in one set. Therefore, all choices except the second choice have repetitive domains.

Thus, not making them a function but rather a relation instead for other choices. The only relation that is a function here is the second choice.

the second one because the x values should not have repeating numbers

Step-by-step explanation:

Hanna have to walk her bike for 1/12 mile to complete the loop .

In the question , it is given that

distance Hanna had to ride to complete the loop  = 11/12 mile

distance rode by Hanna before rest = 1/2 mile

distance rode by Hanna before flat tire = 1/3 mile

So the distance Hanna has to walk her bike to complete the loop = total distance of the loop - distance rode by Hanna before rest - distance rode by Hanna before flat tire .

On substituting the values from above we get ,

distance Hanna has to walk her bike to complete the loop = 11/12 - 1/2 - 1/3

taking the LCM of 12 , 2 and 3 as 12

we get ,

= 11/12 - 6/12 - 4/12

Simplifying further we get ,

= (11-6-4)/12

= (11-10)/12

= 1/12

Therefore , the distance Hanna have to walk her bike to complete the loop is 1/12 mile .

Answer:

Step-by-step explanation:

We can immediately elimate two answers since x cannot be larger than the hypotenuse, which is 9. You can cosine = adjaent/hypotenuse, which gives the equation cos(54) = x/9, which simplifies to x = 9*cos(54). When you plug this into a calculator, you should get 5.29. Keep in mind that 54 is measured in degrees and not radians because.

Answer:

D.) x = 5.29

Step-by-step explanation:

first find the last angle measure 180-90-54=36

use law of sines to find x

sin90/9=sin36/x

(sin90)(x) = (sin36)(9)

(sin90)(x) = 5.29

x = 5.29

Step-by-step explanation:

Let the number of callories that are in one cheeseburger be = x

Let the number of calories that are in one medium frys be = y

Therefore, the question can be formed into an expression as:

Jerry = 1x + 1y = 1200

Joe = 2x + 1y = 1260

x + y = 1200 ....... i

2x + y = 1260 ....... ok

Subtract equation i from ii

x = 60

Therefore, number of callories that are in one cheeseburger is 60 calories

Since x + y = 1200

60 + y = 1200

y = 1200 - 60

y = 1140 calories

The number of calories that are in one medium frys is 1140 calories

Answer:

Step-by-step explanation:

It is stated that a function rule takes an input, and converts it into an output, y, by decreasing twice the input by 4.

Let 'x' be the number

Decreasing twice the number 'x' by 4 = 2x-4

Now,

Given the input x = 5

As the output will decrease twice the input (x=5) by 4

Thus, the output = 2(5)-4 = 10-4 = 6

Therefore,

Answer and Step-by-step explanation: x represent the number of $5 bills and y, the number of $10 bill and, in total there are 32 bills, so

x + y = 32

In terms of value, there is a total of $220. The equation for it is

5x + 10y = 220

The 2 equations which best represent the scenario are

x + y = 32 (I)

5x + 10y = 220 (II)

To know how many bills there are, we have to solve the system. There are many way to solve it and one of them is

1) Multiply (I) by -5:

-5x - 5y = -160 (III)

2) Add equation (III) to equation (II):

-5x - 5y = -160

5x + 10y = 220

0x + 5y = 60 (IV)

3) Solve equation (IV)

5y = 60

y = 12

4) Replace value of y in equation (I) and find value of x:

x + 12 = 32

x = 20

In the proposed scenario, Shondra had 20 $5 bills and 12 $10 bills.

Answer: x=20 and y=12
