Answer 1

Answer:

Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.

( g o f ) = ( 7 x + 1 ) − 1 7  this will result in (gof)=x ( f o g) = 7 x − 1 7 +1 = x − 1 + 1 =x

graphically you can check this if it seems that the functions are reflected over the line x=y.

Slope intercept form is y = mx + b

So the slope intercept form for -5 and 2 is
y = 2x - 5

It would be this because the mx represents the slope and the b represents the y intercept so all you have to do is plug in the numbers.

a bus accelerates from 2 m/s to 10 m/s in 5 seconds. What was its average acceleration?

Please Help

Answers

Answer:

I believe the answer is 4. Please correct me if I’m wrong.

Step-by-step explanation:

Answer:  1.6 m/s^2

================================================

Work Shown:

A = old velocity = 2 m/s

B = new velocity = 10 m/s

C = change in time = 5 seconds

D = average acceleration

D = (change in velocity)/(change in time)

D = (B-A)/C

D = (10-2)/5

D = 8/5

D = 1.6 m/s^2

The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

A family's home is currently worth $1,553,426, which is 70% higher than the home was
worth when they bought it. What was the value of the home when they bought it?

Answers

Answer:

The value of home when bought was $913,780.

Step-by-step explanation:

Given that:

Current worth of the house = $1,553,426

This is 70% more than the original worth of the house.

Let,

100 be the original percent and x be the original worth

Percent increase = (100+70)% = 170%

170% of x = $1,553,426

[tex]\frac{170}{100}x=1553426[/tex]

1.7x = 1553426

Dividing both sides by 1.7

[tex]\frac{1.7x}{1.7}=\frac{1553426}{1.7}\\x= 913780[/tex]

Hence,

The value of home when bought was $913,780.

The CEO of a cell-phone company has recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June’s sales. If y represents July’s sales, which equation can be used to determine the sales in July?

Answers

Answer:

y = n - 0.26n

y = 0.74n

Step-by-step explanation:

The equation that can be used to express the function above is given an Exponential Decrease function

Where:

y = a(1 - r)^t

Where

y = July sales

a = n = June sales

r = rate of decrease = 26% = 0.26

t = time in months = June to July = 1 month

t = 1

Hence, our equation =

y = n( 1 - 0.26)¹

y = n(1 - 0.26)

y = n - 0.26n

y = 0.74n

The equation that can be used to determine the sales in July is given as:

y = n - 0.26n

y = 0.74n

The price p of a pizza is $6.95 plus $0.95 per topping t on the pizza, write a function rule

Answers

Answer:

y= 6.95+0.95t

Step-by-step explanation:

Given data

The price p of a pizza is $6.95

plus $0.95 per topping

let the number of toppings be  t

and let the total cost be y

Hence for any number of topping t the cost function is

[tex]y= 6.95+0.95t[/tex]

The function rule for the prize of a pizza is

[tex]P=0.95t +6.95[/tex]

Given :

The price p of a pizza is $6.95 plus $0.95 per topping t on the pizza

Initial price of the pizza is 6.95

The cost of each topping is 0.95 .

Let 't' be the number of toppings on the pizza

Price of  a pizza = initial cost of pizza + cost per pizza ( number of toppings)

[tex]p=6.95 +0.95(t)\\P=0.95t +6.95[/tex]

The function rule for the prize of a pizza is

[tex]P=0.95t +6.95[/tex]

Answer:

0.6b-3c

we can use dispributive property because of the parentheses

by distributing 0.2 to 3b and -15c

we get 0.6b and -3c

Michael bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?

Answers

Answer:

$183.60

Step-by-step explanation:

Take the regular price and find the 15% discount:

200 x 0.15 = 30

Subtract the discounted amount from the original price:

200 - 30 = 170

Take the new price and find the sales tax:

170 x 0.08 = 13.60

Add the sales tax to the discounted price:

170 + 13.60 = 183.60
