To write an equation and simplify it, I'll start with this:
$4,500 = $90 + $39X Let X represent the amount of people attending the party.
Subtract 90 and both sides of the equation to make the $39X alone.
$4,410 = $39X
Divide $39 into both sides of the equation to isolate or bring X alone.
113.076923 = X
Now since we have to round down, we will do 113.
Answer: 113 people can attend the anniversary party.
Answer:
1x + 4y = 4 ⇒ 6x + 24y = 24
6x - 8y = 0 ⇒ 6x - 8y = 0
32y = 24
32 32
y = 3/4
x + 4(3/4) = 4
x + 3 = 4
-3 -3
x = 1
(x, y) = (1, 3/4)

1/8 divided by 2/5 is 5/16 or 0.3125
<span>Find the inverse function of f.
f(x)=(1+3x)/(5-2x)
Interchange x and y to get:
x=(1+3y)/(5-2y)
Solve for y as follows:
5x-2xy=1+3y
3y+2xy=5x-1
y(3+2x)=5x-1
y=(5x-1)/(2x+3)
this is the inverse function</span>
A.
5x+12=3x+18
2x+12=18
2x=6
x=3
you would get paid the same amount if you worked 3 hours at each job
B.
5(5)+12
10+12
22
3(5)+18
15+18
33
you would get paid more at the second job if you worked for 5 hours
