The graph below shows the relationship between the number of months different students practiced tennis and the number of matches they won:
Part A: What is the approximate y-intercept of the line of best fit and what does it represent?

Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope.

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops

Answer:

-19

Step-by-step explanation:

x= -5       y = -2

-x^2 - 4xy + y^2

- -5^2 -4(-5 x -2) -2^2                      Plug in

+ 5^2 -4(-5 x -2) -2^2                      Change the signs for - -5

  5^2 - 2^2 - 4(10)                           Place Liked Terms together

  25 - 4 - 40                                    Subtract

      21 - 40

         -19

Answer:

the answer is -8

Step-by-step explanation:

this is because when you subtract four from negative four you add the negative four and it becomes 8 but since it'snegative it would be -8

Step-by-step explanation:

The absolute value of a positive is that same number

For example the absolute value of 4 is 4

The absolute value of a negative is that same number without the negative sign.

For example, the absolute value of -4 is 4

Answer:

r+c=80

.50r+.10c=20

Step-by-step explanation:

each rose costs $0.50

each carnation costs $0.10

The number of roses is r, and the number of carnations is c.

the arrangement has a total of 80 flowers, so we have that:

r + c = 80

the cost is $20, so we have:

r*0.5 + c*0.1 = 20

so our system of equations is:

r + c = 80

r*0.5 + c*0.1 = 20

and we can also solve it; for this isolate one of the variables in the first equation:

r = 80 - c

now let'r replace this in the second equation:

(80 - c)*0.5 +c*0.1 = 20

40  - c*0.4 = 20

c = 20/0.4 = 50

this means that we have 50 carnations, and the other 30 are roses.

i was so lost that i almost forgot the answer was in my face

hope this help shawty

Since a^2 - b^2 = 1, the value of y = 1 because x=1 and 1^2 - 1^2 = 0

Answer: I think the answer is 32 bacteria after 40 minutes.

Step-by-step explanation:

I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

See attachment for complete question

Given

Malcom's Family:

[tex]d = 65t[/tex]

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

[tex]t = 1; d = 50[/tex]

[tex]t = 2; d = 100[/tex]

First, we determine the slope, m:

[tex]m = \frac{d_2 - d_1}{t_2 - t_1}[/tex]

[tex]m = \frac{100 - 50}{2- 1}[/tex]

[tex]m = \frac{50}{1}[/tex]

[tex]m = 50[/tex]

Next, we determine equation for Theo's family using:

[tex]d - d_1 = m(t - t_1)[/tex]

[tex]d - 50 =50(t - 1)[/tex]

[tex]d - 50 =50t - 50[/tex]

Add 50 to both sides

[tex]d - 50 +50=50t - 50 + 50[/tex]

[tex]d =50t[/tex]

So, we have the following:

[tex]d = 65t[/tex] --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

[tex]d =50t[/tex] --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

[tex]Rate = 65t - 50t[/tex]

[tex]Rate = 15t[/tex]

Which implies that Malcom's family travel 15 miles per hour faster than Theo's
