If a + b = -6 and x + y + z = -2, what is 8a - 7x - 7z - 7y + 8b
Oxana [17]

Answer:

-34

Step-by-step explanation:

a + b = -6

x + y + z = -2

We want 8a so multiply the first equation by 8

8( a + b) = -6*8

8a+8b = -48

We also want -7x so multiply the second equation by -7

-7(x + y + z) = -2*-7

-7x-7y-7z = 14

Add the two equations together

8a+8b = -48

-7x-7y-7z = 14

-------------------------

8a+8b-7x-7y-7z = -34

Rearranging the order

8a - 7x - 7z - 7y + 8b = -34

What is the equation of this line?
dezoksy [38]

Answer:

A. y = 2x - 3

Explaination:

It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.
