Answer 1

Answer:

1. 8602 - 9895 = -$1293.00

2.10220 - 9895 = $325.00

3. They will not be able to save $1500 a month unless they start following their budget. Their actual expenses go way over budget on entertainment, food, and credit cards. But if they'd stick to the budget, they would be able to save the $1500 a month.

Step-by-step explanation:

1. Total budgeted expenses 8602 minus actual expenses 9895 = -1293

Answer 2

Answer:

for this case we have the following function:

$[tex]f (x) = 3x + 6$[/tex]

we must find the inverse of the function, then:

replace f (x) with y: $[tex]y = 3x + 6$[/tex]

we exchange the variables:

$[tex]x = 3y + 6$[/tex]

we solve for "y":

subtracting 6 on both sides of the equation:

$[tex]x-6 = 3y$[/tex]

dividing between 3 on both sides of the equation:

$[tex]y = \frac {x} {3} - \frac {6} {3}\\y = \frac {x} {3} -2$[/tex]

we change y by $[tex]f ^ {- 1} (x)$[/tex], and finally we have:

$[tex]f ^ {- 1} (x) = \frac {x} {3} -2$[/tex]

$[tex]f ^ {- 1} (x) = \frac {x} {3} -2$[/tex]
