Solve the system using elimination.
5x + 8y = –29
7x – 2y = –67

(x,y) =( -9,2)

Step-by-step explanation:

This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.

It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation. Using the elimination method, multiply the second equation by 4, the result is

28x - 8y = -268

Add to the first equation given

5x + 28x + 8y - 8y = -29 -268

33x = -297

x = -297/33

= -9

substitute the value of x into  the first equation

5(-9) + 8y = -29

8y = -29 +45

8y = 16

y = 16/8

= 2

the image of (6, 9) under a dilation is (4, 6). the scale factor is

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
