Which of the following function pairs are inverses? Options and questions below:

kolbaska11 [484]

Answer:

Second choice

Step-by-step explanation:

To find inverses, we follow the steps:

1. exchange variables x and y

2. solve for y in terms of x.

The resulting function is the inverse.

Take case 2 as an example:

f(x) = y = 2x-3

1. exchange x and y : x=2y-3

2. solve for y: x+3=2y => y=(x+3)/2 = g(x)

Since the inverse of f(x) is g(x)=(x+3)/2, the second choice is the answer.

A car travels 17 miles on one gallon of gas.

ehidna [41]

Answer:

$y$ ranges from 2890 miles to 5780 miles.

Step-by-step explanation:

Let us call $y$ the number of miles the car travels, and $x$ the number of gallons of gas that are used, then we have the relationship

$y=17x$ <em>(this says the car travels 17 miles for each gallon of gas).</em>

Now, when $x=170$ , we have

$y=17(170)$

$y=2890\: miles$

and when $x=340$ , we have

$y=17(340)$

$y=5780\:miles$

So, when $x$ goes from 170 to 340, $y$ goes from $2890$ to $5780$ .

Therefore, when $x$ ranges from 170 to 340 gallons, the distance traveled ranges from 2890 to 5780 miles.

The amount of power why solar panel a can produce with an area of x Square meters can be represented by the equation Y equals 10

vodka [1.7K]

Solar panel B produce more power

Step-by-step explanation:

Given that the amount of power produced by solar panel A with an area of x square meters is modeled by equation y=1020x

For solar panel B, find the equation that models the amount of power produced;

Taking points on the linear graph : (1,1200) and (2,2400) the slope is given as;

m=Δy/Δx

m=2400-1200/2-1 = 1200/1 =1200

Finding the equation

m=Δy/Δx

y-1200/x-1 =1200

y-1200 = 1200x-1200

y= 1200x

Comparing the two models , when area of solar panel is 2 square meters power produced will be;

Panel A, Y=1020x = 1020*2 = 2040 watts

Panel B, Y=1200x =1200*2 =2400 watts

Hence solar panel B produces more power.
