Answer:
-15b +7a
Step-by-step explanation:
If you use FOIL to multiply these two brackets, it will lead you what is exactly written (xa+xb+ya+yb)
so it is correct
A
Answer:
Step-by-step explanation:
Somebody plays 30 times
L+W = 30, where L and W are number of losses and wins, respectively.
L = 30-W
Net after 30 plays is $6
2W - 1L = 6
2W - (30-W) = 6
3W = 36
W = 12
W = 18
17 wins
y - 0 = 5(x-4)
y = 5x-20
5x - y = 20 Standard Form
Answer:
see explanation
Step-by-step explanation:
g(x) - f(x)
x - 3 - (3x + 2) ← distribute parenthesis by - 1
= x - 3 - 3x - 2 ← collect like terms
= - 2x - 5
There are no restrictions on the domain of - 2x - 5, thus
domain is all real numbers
