B. x = 1
C. all real numbers except x = 1
D. all real numbers

2(x + 7) - 1 > 15                 3(x + 2) < 2x + 7
2x + 14 - 1 > 15                  3x + 6 < 2x + 7
2x + 13 > 15                       3x - 2x < 7 - 6
2x > 15 - 13                        x < 1
2x > 2
x > 2/2
x > 1

so, x > 1 OR x < 1.....all real numbers except 1

If I make $7.25 a hour and I work for three days how much money is that every two weeks

Answers


There are a couple of things you didn't mention. 
In order to come up with an answer to the question,
I have to assume reasonable numbers for them, and
then answer the question that I have invented.

Assumption #1:  Each day that you work, you work for 8 hours.

Assumption #2:  You work for three days each week.

If those assumptions are true, then you earn

  ($7.25 / hour) x (8 hours/day) x (3 days/week) x (2 weeks)  =

       ($7.25 x 8 x 3 x 2)  =  $348  before taxes and other deductions.
I am pretty sure it would be $43.50 every two weeks because $7.25 x 3 is 21.75 and then for two weeks add 21.75 +21.75

Locate the foci of the ellipse. Show your work.

x^2/36+y^2/11=1

Answers

a^2 - c^2 = b^2; where \ a = 6, b = \sqrt11 \n 36 - c^2 = 11 \n c^2 = 36-11=25 \n c= \pm 5
Therefore, foci = (-5, 0) and (5, 0)

Choose the correct symbol to complete the statement.4.105 _____ 4.15

<
>
=

Answers

The correct inequality symbol would be <, 4.105<4.15. This is because 4.15 is larger than 4.105. When the right side number is greater than the left side, the inequality symbol would be <. But if its the other way, that the laft side is greater than the right side, the symbol would be >.

Answer:

<

Step-by-step explanation:

4.15 is a larger number than 4.105. So it would look like 4.105<4.15
