x = -3

So to figure this out we can readjust the equation to make it easier to solve

$f(x) = x + 9$ is equal to $x+9 = 6$

From here we can just subtract 9 from both sides and we get our answer!

$x+(9-9) = (6-9)\\x = -3$

20.) Which inequality represents the solution on the graph?*

VMariaS [17]

Answer:

Option 2

Step-by-step explanation:

You can see that the graph of the inequality is x <= -3, so you want to find why inequality matches that. Solve each one:

. $3x \geq -9\\x \geq -3$

doesn't match

$-7x\geq 21\\x\leq -3$

Does match, so this is the answer.

Given the line below.

Roman55 [17]

Answer:

The equation of the line in point slope form is equal to

$y+2=(x+2)$

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,-2) and (2,2)

substitute the values

$m=\frac{2+2}{2+2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(x1,y1)=(-2,-2)$

substitute the values in the formula

$y-(-2)=(1)(x-(-2))\\y+2=(x+2)$

Rename the number to 120,000 ten thousand

Ray Of Light [21]

120,000 renamed to ten thousand (10,000) is twelve ten thousand. Ten thousand in number form is 10,000. When you divide 120,000 (one hundred and twenty thousand) by 10,000 (ten thousand) you get 12. 120,000 (one hundred and twenty thousand) /10,000 (ten thousand) = 12. So there are twelve ten thousands in 120,000.
