Answer: \frac{x+42}{-5}

Step-by-step explanation:

To find the inverse of a function, follow these steps:

First step: Rewrite f(x) as y

y=-5x-42

Second step: Swap x and y.

x=-5y-42

Third step: Solve for y.

x+42=-5y\\\frac{x+42}{-5}=y

A rectangular box has a length of 8 feet and a width of 2 feet. The length of the three-dimensional diagonal is 10 feet. What is
harkovskaia [24]

Answer: h=5.66ft

Step-by-step explanation:

Observe the picture attached.

Find the value of "x" and "y" using the Pythagoren Theorem:

a^2=b^2+c^2

If you solve for "a":

a= \sqrt{b^2+c^2}

Where "a" is the hypotenuse and "b" and "c" are the legs.

In this case, for "x" you know that:

a=x\\b=8ft\\c=2ft

Then, the value of "x" is:

x=\sqrt{(8ft)^2+(2ft)^2}\\\\x=8.24ft

For "y" you can see that:

a=10ft\\b=8.24ft\\c=h

Subsituting values and solving for h, you get:

(10ft)^2=(8.24ft)^2+h^2\\\\h=\sqrt{(10ft)^2-(8.24ft)^2} \\\\h=5.66ft

Y=50x+550

This is a linear equation of the form:

y=mx+b, where m=rate of change or slope and b=y-intercept.

The slope is the rate of change and the y-intercept is the value of y when x=0, which is the initial value.  So in this context...

The change per week is $50.

The starting amount was $550

Distance = change in velocity*change in time
We can find the distance to her grandmas house by plugging in the know info.
Her velocity is 50MPH and her change in time is 3 hours and 3 minutes. Change those minutes into hours by diving by 60 minutes. 3/60 = 0.05 hours. So her total time is 3.05 hours. Do 3.05 hours times the 50MPH, notice the hours cancel and you get miles, 152.5 miles.

Now in the second problem, they give rate but we want time now. And we just solved the distance.
152.5 miles = 53MPH(t)
T being the time it takes
Divide the two numbers and the miles unit cancels, and you’re stuck with hours, 2.88 hours.
