Two different linear functions are shown below with two points given from each function. Use slope-intercept form or point-slope form to find the equation of each. Linear Function A Points: (–5, –2), (–5, 7) Linear Function B Points: (7, –5), (–2, –5) Function A has a slope of -7a slope of 0a slope of 9no slope. The equation of line A is x = -5y = -5x = -2y = 7. Function B has a slope of -7a slope of 0a slope of 9no slope. The equation of line B is x = -5y = -5x = -2y = 7.​

Answer:

There is a dilation and the scale factor is 4

Step-by-step explanation:

The details that complete the question are:

△ABC

A(2, 5), B(6, 10), C(9, −1)

△A′B′C′

A′(0.5, 1.25), B′(1.5, 2.5), C′(2.25, −0.25)

Checking if there is dilation or not

To do this, we make use of the following scale factor (k) formula:

[tex]k = \frac{Original}{Image}[/tex]

Using A and A'

[tex]k = \frac{A}{A'}[/tex]

[tex]k = \frac{(2,5)}{(0.5,1.25)}[/tex]

Factorize the numerator

[tex]k = \frac{4(0.5,1.25)}{(0.5,1.25)}[/tex]

[tex]k = 4*\frac{(0.5,1.25)}{(0.5,1.25)}[/tex]

[tex]k = 4 * 1[/tex]

[tex]k =4[/tex]

Using B and B'

[tex]k = \frac{B}{B'}[/tex]

[tex]k = \frac{(6,10)}{(1.5, 2.5)}[/tex]

Factorize the numerator

[tex]k = \frac{4(1.5, 2.5)}{(1.5, 2.5)}[/tex]

[tex]k = 4*\frac{(1.5, 2.5)}{(1.5, 2.5)}[/tex]

[tex]k = 4 * 1[/tex]

[tex]k =4[/tex]

Using C and C'

[tex]k = \frac{C}{C'}[/tex]

[tex]k = \frac{(9, -1)}{(2.25, -0.25)}[/tex]

Factorize the numerator

[tex]k = \frac{4(2.25, -0.25)}{(2.25, -0.25)}[/tex]

[tex]k = 4*\frac{(2.25, -0.25)}{(2.25, -0.25)}[/tex]

[tex]k = 4*\frac{(2.25, -0.25)}{(2.25, -0.25)}[/tex]

[tex]k = 4 * 1[/tex]

[tex]k =4[/tex]

The above shows that k is 4 in all cases.

Hence, there is a dilation and the scale factor is 4

Answer:

(2.67,-8)

Step-by-step explanation:

You first make x 0 so it is -3x0 to cancel that out to find y. You then see that you get -y=8 so you make y positive by moving the negative to the other side to get y = -8. Then, you do the same type of process for x and get 2.67. I could be wrong but wanted help as much as I could!

Answer: D, 6km/hr.

Step-by-step explanation:

Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.

How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.

12 ÷ 2 = 6.

Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.

Maria and Don has claimed $1839.8 as a medical deduction.

Calculate medical expenses after removing medical insurance expense, that is

20,800 - 60% of 20,800

= 12480

Now, 20,800-12480

=$8,320

Now calculate 10% of gross income

10% of 101,598

= 10/100 × 101,598

= 0.1 × 101,598

= $10,159.8

Now medical deduction = 10% of income - Medical expenses

= 10,159.8-8,320

= $1839.8

Therefore, the medical deduction is $1839.8.

Have a nice day

The 0.317 spray bottle did she ​us.

It is required to find how much of the bottle did she ​use.

A fraction having whole numbers for the numerator and denominator. A fraction is a number of the form: ab where a and b are integers and b≠0. It represents the division of two numbers.

Given:

We know that total =1

For a cleaning solution=3/7 of a spray bottle

Used=1/9

According to given question we have,

Subtract the fractions

3/7 - 1/9

Calculate the difference,

=20/63

=0.317

Therefore, the 0.317 spray bottle did she ​us.

Step-by-step explanation:

Answer:

It only has one solution.

Step-by-step explanation:

4x-20= -2 (-2x + 10)

Add 20 to both sides

4x-20+20=4x-20+20

simplify:

4x=4x

Subtract 4x from both sides

4x-4x=4x-4

Simplify:

Answer:

3/20

Step-by-step explanation:

Given that :

Share for 5 persons = 3/4 of a whole pizza

Each person gets an equal size of the share :

Hence, share per person :

Portion of pizza / number of persons

3/4 ÷ 5

3/4 * 1/5

= (3*1) / (4*5)

= 3/20

Nothing has been distributed because there is still 5(m^2+9m) which would mean it has not been multiplied by anything yet.

Answer:

1 hour and 45 minutes

and 1 hour

Step-by-step explanation:

x= run

y= walk

5x+2.5y = distance

5x+2.5(1.5)=12.5

solve for x

5x=8.75

x=1.75

1.75 in hours is 1 hour and (60*.75)=45

1 hour and 45 minutes

" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"

We use the same equation

5x+2.5y=distance

we'll assume that they till walked 12.5 miles

which means that

5(2)+2.5y=12.5

solve for y

2.5=2.5y

y=1

1 hour
