Answer:

$f^-^1(x)=\frac{1}{3}x-\frac{5}{3}$

Step-by-step explanation:

To solve for the inverse, we need to switch the variables and solve for y.

Note that f(x) is the same as y or in other words, the output.

f(x) = 3x + 5

y = 3x + 5

~Switch variables

x = 3y + 5

~Subtract 5 to both sides

x - 5 = 3y

~Divide 3 to everything

1/3x - 5/3 = y

~Flip

y = 1/3x - 5/3

Best of Luck!

A rectangle has a perimeter of 84 meters. One dimension is 7 meters. How long is

Lemur [1.5K]

Answer:

The unknown dimension is 35

Step-by-step explanation:

The perimeter of a rectangle is l+l+w+w or 2l+2w (l=length, w=width)

$l+l+w+w=84$

$7+7+w+w=84$

$14+w+w=84$

then we subtract 14 from 84

$w+w=70$

$2w=70$

$\frac{70}{2}=35$

$w=35$

Let's check our answer

$35+35+7+7=84$

Steve,Jerry and Ron were paid $29.25 to remove garden gnomes. They each worked 4 hours, exempt for Ron, who was 1 hour late. How

Alenkasestr [34]

Ron should receive $7.98. Jerry and Steve each worked for 4 hours, while Ron was one hour late, so he worked for 3 hours. Together, they worked for 4*2+3=11 hours, receiving $29.25 in total. Each hour should be paid 29.25/11=2.66 dollars. Ron worked for three hours, so he should receive 3*2.66=7.98 dollars.

What is the value of x?

lesantik [10]

50.6
$\frac{x}{72.6 } = \frac{46.2 - 14}{46.2}$
$x = 32.2 \times 72.6 \div 46.2$
$x = 50.6$
