The cost of 4 belts and 5 ties is $247. Each time costs 3 times as much as a belt. What us the total cost of 1 belt and 1 tie
Makovka662 [10]

Answer:

The total cost of 1 belt and 1 tie is $13 and $39 respectively.

Step-by-step explanation:

Given that,

The cost of 4 belts and 5 ties is $247.

Each tie costs 3 times as much as a belt.

Let the cost of a belt is x and that of a tie is y.

ATQ,

4x + 5y = 247 ...(1)

y = 3x ....(2)

Put the value of y from equation (2) in equation (1)

4x + 5(3x) = 247

4x + 15x = 247

19x = 247

x = 13

Put the value in equation (2)

y = 3x

= 3(13)

= 39

So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.

Find the inverse function of m(x) = 5x - 5 A m-1(x) = 5x + 5 B m-1(x) = -5x + 5 C m-1(x) = x+5/5 D m-1(x) = x+5/-5x
bogdanovich [222]
Hi there!

m(x) = 5x - 5
First replace m(x) by y.

y = 5x - 5
To find the inverse function we must switch the places from the variables x and y.

x = 5y - 5
Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.

x + 5 = 5y
Switch sides.

5y = x + 5
And finally divide both sides by 5.

y =  \frac{x + 5}{5}
And therefore we can conclude the following:

m {}^{ - 1} (x) =  \frac{x + 5}{5}
The answer is C.
~ Hope this helps you!
