A line passes through the points (2,20) and (9,27) Write a linear function rule in terms of x and y for this line.

Answers

Answer 1

Answer: It would be x = y-18

Step-by-step explanation:

When you line them up it would look like this

2,20

9,27

To get to 9 from 27 you would have to subtract 27 by 18 and you would get 9

To get to 2 from 20 you would have to subtract 20 by 18 and you would get 2.

A function has the function rule y = x - 7. If the input is 4, what is the output?

A -11
B 3
C 11
D -3

Answers

C - 11

Solution:
4 = x - 7
4 + 7 = x
11 = x

The output of the function y would be -3 if the input is 4. So, option D is the answer.

Here, the function rule that we have been provided with is ⇒ y = x - 7

Given, the input we need to use is ⇒ x = 4

We use the value of the given in the function rule to get the required output:

y = 4 - 7

y = -3

Therefore, after using the given input 4 and substituting it in the given function rule, we get the output -3.

1.What is the actual measurement of that side of the courtyard? Express your answer in inches and then in feet.
2.If Andre made another courtyard scale drawing at a scale of 1 to 12, would this drawing be smaller or larger than the first drawing? Explain your reasoning.

Answers

1. 165in. and 13.75 ft.
2. It would be smaller because it has a lower scale value
Ex. The first is scaled 60 time and the second is scaled 12 times so the first one of 60 would be scaled 48 times bigger that the second scale to 12.

Hall swam 34 laps in 1 2/3 hours. Find his swimming rate in laps per hour

Answers

1 2/3 = 5/3

5/3 ÷ 5/3 = 1

34 ÷ 5/3 = 34 x 3/5

102/5 = 20.4

20.4 laps per hour

First convert your fraction into a decimal
1 2/3 =1.66
They swam 34 laps so take 34 and divide it by 1.66
34/1.66= 20.48
So his swimming rate is 20.48 laps per hour
