Answer:

f(x) = x - 3

Step-by-step explanation:

y = mx + b

first let's find b, the y-intercept

based on the graph, the y-intercept is (0,-3), so b = -3

immediately, we can eliminate f(x) = 3 - x and f(x) = -3x

comment any questions pls

Answer:

f(x) = x -3

Step-by-step explanation:

The y intercept is where it crosses the y axis. That value is -3

The slope is change in y over change in x

We start at the y intercept and go up +3 and to the right +3 to get to the next point.

The difference is +3/+3 = 1

The slope is 1

Putting this in slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 1x-3

or in function form

f(x) = x -3

A 6000-seat theater has tickets for sale at $28 and $40. How many tickets should be sold at each price for a sellout show to gen

irakobra [83]

Answer:

3,833 for $28

2167 for $40

Step-by-step explanation:

Let X be the number of tickets sold at the price of $24, And Y be the number of tickets sold at the price of $40.

Now, $ 28X will be the revenue generated due to the $28 tickets

And, $40Y will be the revenue generated due to the 40$ tickets.

Now, Total revenue generated should be $194400.

Thus , 28X + 40Y = 194400 -(1).

Also,

Total number of seats in theater is 6000.

So, X + Y = 6000. -(2)

X = 6000 - Y.

Put in equation 1

We get , 168,000 - 28Y + 40Y = 194,400

12Y = 26,000

Y = 2,166.66

Since , Y is of 40 $ so minimum tickets sold should be 2167.

X = 3,833.

I don't understand this question

kotegsom [21]

Answer: The correct answer is the third choice.

Step-by-step explanation: The question is asking you to look at pieces of data from the graph. The best way to do this question is to look at each question to determine whether the statement is true or false.

In looking at the each choice:

First one - The statement is true. Looking at the graph, a 40 and 50 year old person has the same average rate.

Second - The statement is true. Looking at the graph, you can see a steady decline from a 10 year old to a 20 year old person.

Third - The statement is false. A 10 year old and 20 year old do not have the same rate.

Fourth - The statement is true. A 20 and 30 year old have the same heart rate.

Find the value of each variable.

sineoko [7]

Answer:

19. x = 65

20. x = 12

21. x = 35, y = 85

Step-by-step explanation:

19. 2x -10 = 120

2x (-10 + 10) = (120 +10)

2x/2 = 130/2

x = 65

20. 2x + 4x + 108 = 180

6x + (108 - 108) = (180 - 108)

6x/6 = 72/6

x = 12

21. 2x + 25 = 3x - 10

2x + (25 - 25) = 3x (- 10 - 25)

(2x - 3x) = (3x - 3x) - 35

-x/-1 = -35/-1

x = 35

3x - 10 + y = 180

3(35) - 10 + y = 180

105 - 10 + y = 180

(95 - 95) + y = (180 - 95)

y = 85

What is the slope of the line through (-2,3) and (1,1)?

son4ous [18]

The slope of the line is -2/3.

This is found by using the equation y2 - y1/x2 - x1. Filling in for each factor, you would have 1-3/1+2 (since subtracting a negative makes it positive). This will give you a final answer of -2/3.

Here is a graph of the full equation of the line.

I hope this helps!
