Answer:

Part A:  y = 4.5x + 22

Part B:  31 inches

Step-by-step explanation:

Part A:

the y-intercept appear to be at 22

the slope can be found by using the points (0, 22) and (4, 39)

m = 39 - 22

        4 - 0

m = 17 / 4 = 4.3 and this is close to 4.5

Part B:

plug in 2 for 'x' in the equation: y = 4.5x + 22

y = 4.5(2) + 22

y = 9 + 22

y = 31

The perimeter of a flag is 474 inches. The flag is 100 inches tall. How long is it?

Answers

The answer is 136 I hope this helped
Okay let’s go step by step.

If it is 100 inches tall, there are two sides that are the same length since flags are rectangles. 100 x 2 = 200. 474 - 200 = 274. 274 divided by two (we are dividing by two because there are two sides congruent on the flag) is 137.

Write down three integers,all less than 25,whose range is 8 and mean is 11.

Answers

let

x------> the first integer

y------> the second integer

z-----> the third integer

x < y < z < 25

we know that

Median=13

Median=(x+y+z)/3

13=(x+y+z)/3

x+y+z=39------> equation 1

range=10

The range is the difference between the largest number within the set and the smallest number in the set

so

range=z-x

z-x=10------> z=x+10-----> equation 2

to find the solution we will assume different values ​​of x (See the attached table)    

terms

x < y < z < 25

z=x+10

y=39-z-x

The solution can be
