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:
Step-by-step explanation:
x2 - 4x - 12 = 0
x2 - 6x + 2x - 12= 0
x(x - 6) + 2(x - 6) = 0
x + 2 = 0
x = - 2
x - 6 = 0
x = 6
Well, you're given that
. I think the extra information is extraneous, unless there's something more that you forgot to add.
Hope I could be of some assistance. :)
Hello!
The range is all of the y-values in a set of points. They are always ordered from least to greatest. It is written as below.
If we look at the y-values on the graph, we get -2,-3,0,and 3. If we order them, we get -3,-2,0, and 3.
This means our answer is B.
I hope this helps!
