I think it's a.)

Step-by-step explanation:

It says that they already started off with $400 and raise $80 a day, and d stands for the number of days.

It's basically $80 a day being added on to the $400 that was already collected.

So it's 80d+400=7,600

Two numbers multiply to be -40 and add to be 3. What are the numbers?

Algebra:

y= x+4
y= -x+2

Answers

to solve for the variables y and x we substitute the second equation into the first meaning that y = -x +2 you substitute y for (-x+2)
so

(-x +2) = x +4
add x to both sides
2 = 2x + 4
subtract 4 from both sides
-2 = 2x
divide by 2
-1 = x

now plug x back into the original equation

y = (-1) + 4
y = 3

and

y = -(-1) + 2
y = 1 +2
y = 3

there you have it x = -1 and y = 3

Hope this helps ;)

to solve what you need to do is
if y=x+4
and y=-x+2 so both equations have to equal the same thin so
x+4=-x+2
combine like terms and you get x=-x-2
then next equals 2x=-2
divide by 2 and last you get x=-1
