Answer:

You cannot solve this

Step-by-step explanation:

you need at least one value given like x=something or y=something so you can plug it in

if you meant solve for x, then x= -4y+32

John likes to hike during the summer he can usually hike about 3 miles every hour but when it's really hot he swims in a mountai

Nastasia [14]

During the 9 mile hike he spends 2 periods of half hour swimming = 1 hour.
actual hiking time = 3*3 = 9 hours

So total time = 9+1 = 10 hours

Find the inverse function y=-5x+20

Nezavi [6.7K]

Answer:

$y= \frac{-1}{5} x +4$

Step-by-step explanation:

We can find the inverse function of this excercise, isolating X and then changing the variables.

$y=-5x+20\\y-20=-5x\\\frac{y-20}{-5} =x\\$

$\frac{y}{-5}-\frac{20}{-5} = x\\\frac{-1}{5}y+\frac{20}{5} =x\\ \frac{-1}{5}y+4 =x$

And now we change the variables and we get the inverse function:

$y= \frac{-1}{5} x +4$

Hello from MrBillDoesMath!

Answer:

x >= 7

Discussion:

x + 5 >= 12 => add -5 to both sides

x + 5 -5 >= 12 - 5 => as 5-5 = 0 and 12 =5 = 7

x >= 7

Thank you,

MrB
