Answer 2

5Answer:

Step-by-step explanation:

Let the first session be y =20 + 30x .................. equation 1

Let the second session be y = 10 + 35x .............. equation 2

equate the two functions

20 + 30x = 10 + 35x

y = 20 - 10 +30x - 35x

y = 10 -5x

Find the y intercept (that is where y = 0)

10-5x = 0

5x =10

x = 2

substitute x = 2 into equation 1 and 2

y =20 + 30(2) = 80

y = 10 + 35(2) =80

Notice that when you plot the graph for equ. 1 and equ. 2 , it intercepts at x =2 and y =80 (2, 80)

Answer: x = 55°

Step-by-step explanation:

Basically what I did was this.

x - 25° = 45° - 15°

x - 25° = 30°

x = 55°

The reason for how I got is that you have to pretend that there is another parallel line between the x and 45 thats how this equation occurs.

The owner of a resale shop is analyzing the revenue for the year. Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500?

Answers

Answer:

hope this helps with other things have a a good day

Step-by-step explanation:

The required number of items the owner must sell is 15 items so he can earn a $500 profit.

Given that,
Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500 is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
500 = x² - 14x + 485
x² - 14x - 15 = 0
x² - 15x + x - 15 = 0
x (x - 15 ) + 1 (x - 15 ) = 0
(x - 1 ) (x - 15 ) = 0

Number of items he must sell to earn $500 profit,

x - 15 = 0
x = 15

Thus, the required number of items the owner must sell is 15 items so he can earn a $500 profit.

2 [(12 + 2x) + (15 + 2x)]= 74.

Answers

2 [ ( 12 + 2x) + ( 15 + 2x) ] = 74

Divide 2 by both sides.

[ ( 12 + 2x) + ( 15 + 2x) ] = 37

Add the equations in the parentheses.

(27 + 4x) = 37

Remove parentheses.

27 + 4x = 37

Subtract 27 by both sides.

4x = 10

Divide 4 by both sides.

x = 10/4 or 2.5

The width of a rectangular room is 80% of its length. If the length of the room is 20 meters, what is the area of the room? A= length x width

Answers

Answer:320ft^2

Step-by-step explanation:

80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area

A=320^2!
Length x width = area
