Answer:
<u>y = x ( - 3 ) + 1</u>
Step-by-step explanation:
Find what relationship x and y have. In this case, y is x multiplied by -3, plus 1.
(3,-8) The number 3 is x and -8 is y. Use the rule above to see if it's correct. Like so: -8 = 3 ( - 3) + 1
-8 = -9 + 1
-8 = -8
The rule/equation is correct.

Substitute on equation 2, y = -4x + 7. so equation 1 becomes 2x - (-4x + 7) = 6x - 7 = 5. 6x = 12, so x = 2. from above, y = -4x+7 = -4(2) + 7 = -1
Hello there, and thank you for posting your question here on brainly.
Short answer: C. 9
Why?
Box and whisker plots are confusing, the line in the middle is the median, but we don't need to do that now. The dots on the lines outside of the box show the largest and the shortest number. The plotted point on the way left is your answer, the line plotted is 9.

The midpoint formula is basically just the average of the two points. Here it is:
![( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})](https://tex.z-dn.net/?f=%28%20%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%29)
Then, you plug the points in. The answer is (-13,-5/2) or
C
If it self explanatory... just divide the sum of total price by the Size of the item that’s all.. and they are saying the unit should be the same.. and the units too are given so.. you will convert.. then bear in mind that .99 is the same as 0.99 they use it to confused others.. so sum the total price and divide by the Size but let the units be the same... the conversion is given under it
