A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.
Step-by-step explanation:
The inequality is given as;
-3x-7<20 which can be solved as
-3x < 20+7 -----collecting like terms
-3x < 27 -------divide both sides by -3
x > -9 -----change the sign direction because you divided by
plotting the solution x > -9 on a graph tool gives

Answer:
Step-by-step explanation:
Solve for the mean (average) of the five test scores.
Subtract that mean from each of the five original test scores. Square each of the differences.
Find the mean (average) of each of these differences you found in Step 2.
Take the square root of this final mean from #3. This is the standard deviation.
Answer:
We know that x = 10. But, we don't know what f is. In order to find f, we would divide. To divide we would use this formula: 8 ÷ 10. This equals 0.8 or 8 tenths. Now, we know what our <em>f</em> value is. It's 0.8! To double check, use a calculator and type in: 10*0.8 and see if the answer is 8. (Please mark brainliest! :D)

Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>
