-9x-9=-2x+5

Then add 9+14

-9x=-2x+14

Then add 2+-9

-7x=14

So x=-2

Answer:

x = -2

Step-by-step explanation:

So we are given the equation -3(3x + 3) = -2x + 5 and we are solving for x. We will have to try to get the equation into the form x = _. That would be our answer.

-3(3x + 3) = -2x + 5

Distribute the -3 on the left side.

-9x - 9 = -2x + 5

Add 2x to both sides to get rid of the -2x on the right side.

-9x - 9 + 2x = 5

Simplify.

-7x - 9 = 5

Add 9 to both sides to get rid of the - 9 on the left side.

-7x = 5 + 9

Simplify.

-7x = 14

Divide both sides by -7 to get rid of the coefficient of -7 on the left side.

x = 14 ÷ (-7)

Simplify.

x = -2

The answer is x = -2.

I hope you find my answer helpful. :)

Student performance across discussion sections: A professor who teaches a large introductory statistics class (197 students) wit

adell [148]

Answer:

The test is not significant at 5% level of significance, hence we conclude that there's no variation among the discussion sections.

Step-by-step explanation:

Assumptions:

1. The sampling from the different discussion sections was independent and random.

2. The populations are normal with means and constant variance

$H_0:$ There's no variation among the discussion sections

$H_1:$ There's variation among the discussion sections

$\alpha =0.05$

Df Sum Sq Mean sq F value Pr(>F)

Section 7 525.01 75 1.87 0.99986

Residuals 189 7584.11 40.13

Test Statistic = $F= \frac{75}{40.13} =1.87$

$Pr(>F) = 0.99986$

Since our p-value is greater than our level of significance (0.05), we do not reject the null hypothesis and conclude that there's no significant variation among the eight discussion sections.

Which graph represents x - 1 ≤ 3

MAVERICK [17]

The first graph.

The equation is x - 1 $\leq$ 3
In order to solve it, you need to get x by itself.
Add 1 to both sides. 3+1=4
x $\leq$ 4

Since this is your sign $\leq$ the arrow has to point towards the left, and the circle needs to be colored in.
