Factor the equation out into (x-5)(x+3)
(x-5)=0
x=5
(x+3)=0
x=-3
x=5, -3
Answer:
y = -3x + 2

You didn’t include a picture so it’s unsolveable
B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.
Answer:
B. because 40+30+50+20=140
E. because we have the probability
G. probabilty is missing again but im guessing its right
H. probablilty missing
Hope this helps ^^
