Answer:

C

Step-by-step explanation:

Given

9 { \frac{x}{3} + 1 } ≥ 6 ( divide both sides by 9 )

\frac{x}{3} + 1 ≥ \frac{6}{9} , that is

\frac{x}{3} + 1 ≥ \frac{2}{3} ( multiply through by 3 to clear the fractions )

x + 3 ≥ 2 ( subtract 3 from both sides )

x ≥ - 1 → C

Given f(x) and g(x) = k·f(x), use the graph to determine the value of k.<br> g(x)
djyliett [7]
<h2>Explanation:</h2>

The diagram for this exercise is attached below. We have two linear functions f(x) \ and \ g(x) and the following relationship:

g(x) = kf(x)

From the graph, we know that:

f(-3)=1 \\ \\ g(-3)=-3

Then, substituting into the relationship:

g(-3)=kf(-3) \\ \\ -3=k(1) \\ \\ \\ Finally: \\ \\ \boxed{k=-3}

I need help on these two! Can annoying explain?
True [87]

You are solving the two equations for x.

9.

r = 4 + 7x - sx

We need to solve for x. x is only found in the right side. First, just flip the sides to find x only in the left side.

4 + 7x - sx = r

We want all terms with x on the left side, and all terms without x on the right side. Now we subtract 4 from both sides.

7x - sx = r - 4

Factor x in left side.

x(7 - s) = r - 4

Divide both sides by 7 - s.

x = \dfrac{r - 4}{7 - s}

12.

3z + 8 = 12 + 3x - z

Since x is only in the right side, flip the sides.

12 + 3x - z = 3z + 8

We need to isolate x in the left side, so subtract 12 from both sides and add z to both sides.

3x = 3z + 8 - 12 + z

3x = 4z - 4

Divide both sides by 3.

x = \dfrac{4z - 4}{3}
