1 answer:

So first we calculate the weekly hours:
23.80 x 34 = 809.20

Then we calculate the time and half:
23.80 x 6 x 1.5 = 214.2

Then we total then together:
214.2 + 809.20 = 1023.40

Which function is the inverse of f(x)= 3x+5 over 7

Pani-rosa [81]

f(x) = (3x+5)/7

Step 1:

we write f(x) as y

y=(3x+5)/7

Step 2:

switch y by x and x by y

x=(3y+5)/7

Step 3:

solve for y,

x=(3y+5)/7

multiply both sides by 7

7x=3y+5

subtract 5 from left side

3y=7x-5

divide both sides by 3

y= (7x-5)/3

f⁻¹ (x) =(7x-5)/3

Running at a constant rate, austin run 18 miles in a time of 180 minutes. How many minutes does it take austin to run 6 miles

tia_tia [17]

Answer:

60 minutes

Step-by-step explanation:

to find this, we will first determine how long it takes austin to run one mile.

18 miles / 180 minutes

1 mile / 10 minutes

it takes austin to run 10 minutes to run 1 mile

now, we will multiply the number of minutes it takes by 6 to find how long it takes austin to run 6 miles.

1 mile / 10 minutes

6 miles / 60 minutes

it takes austin 60 minutes to run 6 miles
