A) f(x) = x - 4 , g(x) = x + 4 
⇒ f( g(x) ) = x + 4 - 4 = x
    g( f(x) ) = x - 4 + 4 = x
⇒ f and g are not inverses of each other
b) f(x) = -1/(3x) , x ≠ 0 ; g(x) = 1/(3x) , x ≠ 0
⇒ f( g(x) ) = -1/( 3*(1/(3x)) ) = -1/(1/x) = -x
    g (f(x) ) = 1/( 3*(-1/(3x)) ) = 1/( -1/x) = -x
 ⇒ f and g <span>are not inverses of each other</span>

You wish to take a flight from Nevada to New York. Use the point (-4, 0) to represent Nevada, and the (5, 2) to represent New Yo
Flauer [41]

Using proportions, it is found that the ordered pair that represents the location of the layover is given by: (2.75, 1.5).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the flight distance is partitioned in a ratio of 3:1, hence:

L - Nv = 3/4(Ny - Nv).

This ratio is applied for both coordinates, hence, for the x-coordinate:

x + 4 = \frac{3}/{4}(5 + 4)

x = \frac{27}{4} - \frac{16}{4}

x = \frac{11}{4}

x = 2.75.

For the y-coordinate:

y = \frac{3}/{4}(2 - 0)

y = \frac{6}{4}

x = 1.5.

What are the points if the slope is 4 and the point is (1,-1)
kherson [118]

The points if the slope is 4 and the point is (1,-1) are (1,-1) and (2, 3)

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change, slope or gradient

<h3>How to determine the points?</h3>

The given parameters are:

Slope = 4

Point = (1, -1)

The slope of 4 means that as x changes by 1, the value of y changes by 4

This means that, we have:

(x + 1, y + 4)

Substitute the known values in the above equation

(1 + 1, -1 + 4)

Evaluate

(2, 3)

Hence, the points if the slope is 4 and the point is (1,-1) are (1,-1) and (2, 3)

Help please! There are 3 items in an order. They cost $8.95, $11.49, and $12.75. The sales tax for this order is 6.5%.
vredina [299]

Answer: $35.35

Step-by-step explanation:

Facts

3 items

item 1: 8.95

item 2: 11.49

item 3: 12.75

6.5% sales tax

Step 1: Find the total cost of the items ,before tax

8.95+11.49+12.75= 33.19

Step 2: Apply the sales tax

6.5% of 33.19 = 2.15735 --> approximatley $2.16

Step 3: Add the sales tax amount to the total cost of the items to find the final total cost.

$33.19+$2.16= $35.35  

Hence the answer is B

Hope this helps !! :)) And brainliest would be appreciated

Y= -3x with steps please. It’s asking weather it’s a linear equation or not.
tankabanditka [31]
This is a linear equation. since there is no exponent on the x, x is just to the power of 1. anything to the power of 1 is considered a linear equation. you could also do the vertical line test and find that when you plug any number in for x, none of the final answers will repeat each other. i hope this makes sense and that this helps!!
