Answer:
A
Step-by-step explanation:
Solving for x:
-3x + 8 ≥ 14
-3x ≥ 6
x ≤ -2
Notice the sign gets reversed when you divide or multiply by a negative number.
The only option less than -2 is -3, A.
Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation. This can save time on tests like the SAT or ACT.
Let's try it:
-3(-3) + 8 = 9 + 8 = 17
-3(-1) + 8 = 3 + 8 = 11
-3(0) + 8 = 0 + 8 = 8
-3(3) + 8 = -9 + 8 = -1
So you can see the answer is A.

Answer:
6.3 units (nearest tenth)
Step-by-step explanation:
Using the formula above,
distance between (-8, 6) and (-6, 0)
![= \sqrt{ {[ - 8 - ( - 6)]}^{2} + {(6 - 0)}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%20%7B%5B%20-%208%20-%20%28%20-%206%29%5D%7D%5E%7B2%7D%20%20%2B%20%20%7B%286%20-%200%29%7D%5E%7B2%7D%20%7D%20)
= 6.3 units (nearest tenth)
9 + 10 does <u>not</u> equal 21.
If you add 9 and 10, you will get 19.
If you are referring to the meme, ok.
