Answers

50 people would be expected to show up on day 7.

Each day the number of people goes up by four people, 46 + 4 = 50

Therefore there would be 50 people by day 7.
Answer: B

Explanation:

If you look at the number of people, you can see by how many days go by the number of people go up by +4. So, by the seventh day there should be 50 people because 46 + 4 = 50

Answers

Answer:

Step-by-step explanation:

a) 7(25) + 4(10) + 37(5)

   7(20) +7(5) +4(10) + 5(30) + 5(7)

   1.40 + 35 + 40 + 1.50 + 35

   1.75 + 40 + 1.85

   3.60 + 40

  4.00 = 400% of $1

b) 50 + 7(10) + 1.02

   50 + 70 + 1.02

  1.20 + 1.02

  2.22 = 222% of $1

c) 2.00 + 13(5) + 71

   2.00 + 5(3) + 5 (10) + 71

   2.00 + 15 + 50 + 71

  2.00 + 65 + 71

  2.00 + 1.36

  3.36 = 336% of $1

A has a higher percentage of dollar because 400%>336%>222%

What are composite functions?

Functions which are formed by composing two or more functions in a way that one's output is another's input are called composite functions. They are also called function of functions.

We need to find the sum of composite numbers between 13 and 23.

Therefore,

14+15 = 29+16 = 45+18 = 63+20 = 83+21 = 104+22 = 126

The composite numbers between 13 and 23 are;

14, 15, 16, 18, 20, 21, and 22.

Hence, the sum of these numbers is 126.

So the correct option is D.

the slope is -9/7

Answer:

slope = m = -9/7

Step-by-step explanation:

(1,17) (8,8)

4x - 2(x - 2) = -9 + 5x - 8

Answers

Answer is x = 7

Step by step

4x -2(x - 2) = -9 +5x -8
Distribute

4x -2x +4 = -9 +5x -8
Combine

2x + 4 = 5x -17

Subtract 5x from both sides to isolate variable

2x -5x +4 = 5x -5x -17
Combine

-3x +4 = -17

Subtract 4 from both sides to combine constants

-3x +4 -4 = -17 -4
Combine

-3x = -21

Divide both sides by -3 to solve

-3/-3 x = -21/-3

x = 7
