The first one because if you add all the positives you get 4 and then if you add all the negatives you get 7 so then you do 4+(-7)= -3
So u Line them up like the photo then you multiply 2 x 4 = 8 and multiply 3 x 1 = 3 so you get 8/3 then simply 8/3 the answer is 2 2/3
8x + 9 = 42
8x +(9-9)=42-9
8x=33
8x/8=33/8

Answer:
D. y =
Step-by-step explanation:
The solutions to this graph (meaning when y equals 0 or when the graph crosses the x-axis) are 4 and 5.
The only answer choice that has the solutions 4 and 5 when you factor it out is D.
Here's the proof:

Factors of 20: - 5 & -4
Sums that add up to -9: -5 + (-4)

(factor the first two terms and the last two terms separately)


(x - 5) (x - 4)
