Answer: 39$
Step-by-step explanation: calls=x x=30 30*.05= 1.50 40.50-1.50= 39$
Easy, showing work,
using the method FOIL (First,Outer,Inner, Last)
Take, (x+3)(x+5) and multiply,
First,
x*x=

Outer,
x*5=5x
Inner,
3*x=3x
Last,
3*5=15
Add the terms together,

+8x+15 (

+5x+3x+15)
Thus, your answer.
Answer:
g(2) = 5
g(-2) = 2
g(-3) = 0
g(5) = 1
g(x) = 0 when x = 3
g(x) = 6 when x = 0
Step-by-step explanation:
Your just finding the values of y when x is unknown or when y is unknown and your trying to find x. f(x) is just a fancy way of saying y.
X - $5 bills
y - $10 bills
x + y = 12
y = 5x
x + (5x) = 12
6x = 12
x = 2
y = 5(2)
y = 10
10 $10 bills and 2 $5 bills
