Which equation does not belong? Explain your reasoning 2x + y = 4 y = -2x + 4 f(x) = -2x + 4 2x + 2y = 4

Answers

Answer 1

Answer:

2x + 2y = 4  does not belong

Step-by-step explanation:

2x + y = 4     → y = -2x + 4

y = -2x + 4    → y = -2x + 4

f(x) = -2x + 4 → y = -2x + 4

2x + 2y = 4   → y = -x + 2

When twelve is added to eight times a number, the result is one hundred and fifty. Find the
number.

Answers

Adding twelve eight times is the same as 12 x 8 which is 96

x + 96 = 150

To find 150, subtract 96 from both sides

x = 150 - 96
x = 54

The test scores for 10 students were: 74, 81, 39, 74, 85, 80, 100, 92, 74, and 85. What
is the mode?

Answers

Answer:

74

Step-by-step explanation:

"The mode is the value that appears most often in a set of data values."

So, if we look at this data, we can conclude that the mode is 74 because 74 appears 3 times (with 85 being second at twice).

The area of the table should be
10 ft2. You want the length of the table to be 1 ft shorter than twice its width.
What should the dimensions of the table be?

Answers

Answer: width : 2.5 ft. and length : 4 ft.

Step-by-step explanation:

The area = W × L

[tex]10=W(2W-1)[/tex]

[tex]10=2W^{2} -W[/tex]

[tex]0 = 2W^{2}-W-10[/tex]

[tex]0=(2W-5)(W+2)[/tex]

W = 2.5 and -2

You can't use -2 so

[tex]L = 2(2.5)-1[/tex]
