how do you figure out if functions are inverses or not

Answers

Answer 1

Answer:

For instance, if the point (1, 3) is on the graph of the function, then the point (3, 1) is on the graph of the inverse. That is, if you start with x = 1, you will go to y = 3; then you plug this into the inverse, and you'll go right back to x = 1, where you started from.

Step-by-step explanation:

Answer 2

Answer:

Well, we learned before that we can look at the graphs. Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

An electrician charges $75 to come to your property and $45 per hour. If the equation y = 45x + 75 represents this situation, what does "x" represent? * 1 point the total cost of his visit the amount he earns per hour the one-time fee for showing up the number of hours he works

Answers

Answer:

Y is the total cost of his visit

Step-by-step explanation:

This expression is similar the same as the equation of a straight line, so we could actually compare the expression and come up with an answer.

the equation of a straight line is

y=mx+c

y=45x+75

What does "x" represent?

x represents the number of hours worked by the electrician.

y represents the total cost of his visits

Answers

Answer:

Slope is -3

Good Luck!!!

Answer:

Slope = -3

Step-by-step explanation:

First let's convert Standard Form to Slope-Intercept Form.

Slope intercept form is y = mx + b.

Let's start converting now!

[tex]12x + 4y = 7[/tex]

[tex]4y = -12x + 7[/tex]

[tex]y = -\frac{12}{4}x + \frac{7}{4}[/tex]

[tex]y = -3x + \frac{7}{4}[/tex].

The -3 represents the slope (m).

Therefore, the slope is -3.

Find the measure of angle A.

Answers

Answer:

2x-9

Step-by-step explanation:

Answer: ∠A = 65°

Step-by-step explanation:

All angles in a triangle add up to 180°.

Firstly, you need to solve for x.

Set all angles equal to 180°:

2x - 9 + 2x + 4 + x = 180

Combine like terms:

5x - 5 = 180

Add 5 to both sides:

5x = 185

Divide both sides by 5:

x = 37

Now, plug x into angle A:

∠A = 2(37) - 9

∠A = 74 - 9

∠A = 65°

In physics, the Ideal Gas Law describes the relationship among the pressure, volume, and temperature of a gas sample. This law is represented by the formula PV = nRT, where P is the pressure, V is the volume, T is the temperature, n is the amount of gas, and R is a physical constant. Which of the equations below are equivalent to the formula PV = nRT? Select all that apply.

Answers

The question is incomplete, the complete question is;

Answer:

B. V = nRT/P

n = PV/RT

Step-by-step explanation:

The equation PV=nRT is called the ideal gas equation. If we make V the subject of the formula, then we have; V = nRT/P

Similarly, if we make n the subject of the formula we have n = PV/RT.

These two equations are equivalent to the original equation PV=nRT

Pick two points on the line

(0,2) and (2,3)

Using the slope formula

m = ( y2-y1)/(x2-x1)

= ( 3-2)/(2-0)

= 1/2

We have the y intercept = 2

Then using the slope intercept

y = mx+b where m is the slope and b is the y intercept

Answer:

[tex]\boxed{-\frac{17}{40} }[/tex]

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator.

Then

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

And then....

Find the Greatest Common Factor (GCF) of 425 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25.

Therefore x = -17/40

In conclusion, – 0.425 = -17/40

Two landscapers must mow a rectangular lawn that measures 95 feet by 170 feet. Each wants to mow no more than half of the lawn. The first starts by mowing around the outside of the lawn. The mower has a 24-inch cut. How wide a strip must the first landscaper mow on each of the four sides in order to mow no more than half of the lawn? (Round your answer to three decimal places.) Approximate the required number of trips around the lawn the first landscaper must take. (Round your answer to one decimal place.)

Answers

Let w is the width of the strip mowed by the outer mower as shown in the figure. So, the area mowed by the outer mower is the area of the shaded region.

Each wants to mow no more than half of the lawn, so, both have to mow exactly half of the area of the lawn.

The length of the rectangular lawn, [tex]l=170[/tex] feet

and the width, [tex]b=95[/tex] feet.

The dimensions [tex]( l'\times b')[/tex] of the area left to the other mower are

[tex]l'=170-2w[/tex] and [tex]b'=95-2w[/tex].

As. both most have to mow half of the lawn, so

[tex](170-2w)\times(95-2w)=\frac{170\times95}{2}[/tex]

[tex]\Rightarrow 4w^2-530w+8075=0[/tex]

[tex]\Rightarrow w=17.5641, 114.9358[/tex]

Ignoring the higher value as w cant be more than the dimension of the lawn.

So, the required width of the strip

w=17.564 feet (rounded up to three decimal places)

As the outer mower has a 24-inch cut, so in 1st trip, he cuts the 24-inch or 2 feet of required width.

So, the number of the required trip is

[tex]\frac{17.564}{2}=8.782[/tex]

=8.8 (rounded up to one decimal place)
