What is the inverse of the function f(x) = 2x - 10?
h(x) = 2x - 5
Oh(x) = 2x + 5
5
(x) = {x-5
- 2x+5
h(x) =

Answers

Answer 1

answer:

f(x)=2x-10

y=2x-10

interchanging value of x and y,

x=2y-10

y=(x+10)/2

so inverse of given function is (x+10)/2

Answer 2

Answer:

Step-by-step explanation:

h(x) = one-halfx – 5

Whats the midpoint between 1 and 2

Answers

Answer:

1.5

Step-by-step explanation:

Think of a number line, on the number line are the points 1 and 2, the number between those points is the midpoint.

You can also average 1 and 2 to get the midpoint. To average any number sequence, simply add all of the numbers and then divide the sum of those numbers by the amount of numbers there are.

In this case add 1 and 2 to get 3 then divide 3 by 2 (because there are two numbers) to get 1.5

The midpoint between 1 and 2 is 1.5.

What is the midpoint?

A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.

Given points are 1 and 2. The midpoint is calculated by using the formula as ( x₁ + x₂ ) / 2.

Average 1 and 2 to get the midpoint. To average any number sequence, simply add all of the numbers and then divide the sum of those numbers by the number of numbers there are.

The midpoint will be calculated as:-

M = ( x₁ + x₂ ) / 2.

M = ( 1 + 2 ) / 2.

M = ( 3 ) / 2.

M = 1.5

Therefore, the midpoint between 1 and 2 is 1.5.

Kennith and three of his friends shared a basket of apples. The basket weighed 14.75 pounds. What is the weight of the apples that each of them recieved

Answers

Answer:

3.6875 lbs per person

Step-by-step explanation:

Calculation for the weight of the apples that each of them recieved

Based on the information given we were told that Kenneth shared the basket of apples with 3 of his friends which means that they are 4 in total which is Kenneth + 3 of his friends.

Hence,

Weight of apples=14.75 pound/4

Weight of apples=3.6875 lbs per person

Therefore the weight of the apples that each of them received will be 3.6875 lbs per person

Answers

Answer:

[tex]h(t) = -5(t-2)^2+20[/tex]

20 meters

Step-by-step explanation:

The vertex form of the equation is h(t) = -5(t-2)^2 - 4 and the ball was 20 meters above the ground

Vertex form of an expression

The standard vertex form of a quadratic equation is expressed as (a-h)^2 + k

Given the height of the ball (in meters above the ground) t seconds after Sara kicked it is modelled by h(t)=-5t^2+20t

Write in vertex form

h(t)=-5t^2+20t

h(t) = -5(t^2 - 4t)
h(t) = -5(t^2 - 4t + 2^2) - 2^2
h(t) = -5(t-2)^2 - 4

Hence the vertex form of the equation is h(t) = -5(t-2)^2 - 4

At the highest point t = -b/2a
t = -20/2(-5)
t = -20/-10
t = 2ssecs

Substitute t = 2 into the function

h(2) = -5(2)^2 + 20(2)
h(2) = -20 + 40
h(2) = 20 meters

Hence the ball was 20 meters above the ground

A quantity of 22% acid solution is being diluted with some 8% acid solution. The final solution must be 12% acid and contain 101 mL. How much of each solution must be added to achieve the result? ROUND TO THE NEAREST mL.

Answers

Answer:

Amount of 22% acid solution needed = 29 ml

Amount of 8% acid solution needed = 72 ml

Step-by-step explanation:

Let x=amount of 22% solution needed

Then 101 - x= amount of 8% solution needed

The pure acid in the 22% solution (0.22x) plus the amount of pure acid in the 8% solution 0.08(101 - x) has to equal the amount of pure acid in the final mixture (0.12*101).

The equation to solve is:

0.22x + 0.08(101 - x) = (0.12*101)

0.22x + 8.08 - 0.08x = 12.12

0.14x = 12.12 - 8.08

0.14x = 4.04

x = 4.04 / 0.14

= 28.86

x = 29 ml to the nearest ml

Amount of 22% acid solution needed = 29 ml

Amount of 8% acid solution needed = 101 - x

= 101 - 29

= 72ml

Weight of one cabbage = 2 3/8 pounds

6 cabbage will weight x pounds

Use the equality postulate to find x:

1 cabbage = 19/8 pounds

6 cabbages = x pounds

Cross multiply

1 * x = 6 * 19/8

x = 114/8

target sells 24 bottles of water for $3, and 36 of water for $4 witch is the better buy and by how much

Answers

Answer:

36 bottles for $4

Step-by-step explanation:

First you need to calculate the price for one bottle, the lower the cost, the better buy. Do this by dividing the price by the amount of bottles:

= $3 ÷ 24

= 0.125 cents

= $4 ÷ 36

= 0.111 cents

The cheaper option and the better buy is the 36 bottles for $4.
