Mathematics
1 answer:
VARVARA [1.3K]4 years ago
6 0

Answer:

(2,3)

Step-by-step explanation:

use the equal values method.

set y equal to itself.

y = -2x+7 but also 5x-7

-2x+7=5x-7   ............................. solve the equation

7x=14

x=2

Now substitute the x value into one of the equations given. for example i'll do -2x+7.

-2(2) +7 =y

-4+7=y

3=y

so thats your answer

x=2, y=3

An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment
stealth61 [152]

Answer:  First option is correct.

Step-by-step explanation:

Enrollment month   Actual   Predicted   Residual

January                   500           8                4

February                 400           15              -1

March                     550            15              -1

April                         13              12              -1

May                         16              17              -1

June                        14              15              -1

Since we know that

Residual value = Actual value - Predicted value

Sum of residuals is given by

4-1-1+1-1-1=1

since we can see that sum of residual is more than 0.

So, it can't be a good fit .

Hence, No, the equation is not a good fit because the sum of the residuals is a large number.

Therefore, First option is correct.

Tamiku [17]

Answer:

<h2>25\pi \:  {ft}^{2}</h2>

Option B is the right option.

Solution,

Radius(r)=5 feet

Area of circle=?

Now,

area = \pi {r}^{2}  \\  \:  \:  \:  \:  \:  = \pi \times  {(5)}^{2}  \\  \:  \:  \:  \:  = \pi \times 25 \\  \:  \:  \:  \:  = 25\pi \: {ft}^{2}

Hope this helps..

Good luck on your assignment..
