Answer:
To solve for y, you want to use the distributive property
First you want to distribute the 8 through the 3y-5 and the 9 through the y-5
8(3y-5)= 24y-40
9(y-5)= 9y-45
24y-40=9y-45 (get the x on one side, so first add 40 to each side)
24y=9y-5 (now subtract 9y to each side)
15y=-5 (divide both sides by 15)
y= -5/15= -1/3
Hope this helps ;)
Answer:
W(-5,-4) Z(-3,6)
Step-by-step explanation:
Since they have the same x-coordinate, you can just find the difference between the y-values.
7 - (-6) = 7 + 6 = 13
It'd be a little more complicted if they didn't have the same x or the same y cooridnates.
