mike charges 100 dollars service charge plus 65 dollars per hour.

amy charges 40 dollars service charge plus 80 dollars per hour.

the cost to repair from mike is 100 + 65 * x.

the cost to repair from amy is 40 + 80 * x.

let x = 3 and you get:

the cost to repair from mike is 100 + 65 * 3 = 295 dollars.

the cost to repaid from amy is 40 + 80 * 3 = 280 dollars.

as long as the time to repair is 3 hours or less, the cost to repair will be cheaper from amy.

Find f(x) if it is known that f(x−6)=12x−72.

zheka24 [161]

Answer:

f(x)=12x

Step-by-step explanation

We know that f(x) is our y-coordinate and x is the x-coordinate

Next we should insert x-6 as x in the equation

This is f(x)=12(x-6)-72

But if you look at this that leads to 12x-72 (ignore y-intercept)

That is our first equation

This means that if you take out -6 from the x

You will get f(x)=12x

What is the Domain of the function indicated by the points on the plane?

kondor19780726 [428]

<h2>Answer:</h2>

A.) {-6, -2, 5}

<h2>Step-by-step explanation:</h2>

A function $f$ from a set $A$ to a set $B$ is a relation that assigns to each element $x$ in the set $A$ exactly one element $y$ in the set $B$ . The set $A$ is the domain (also called the set of inputs) of the function. From the figure, we can see that this set is the x-coordinate of each red point. So this set is {-6, -2, 5}
