Only in grade 9, didn't learn this, but I assume it is...
(m^2+10)(m^2-10)
Answer:
A: y < -2x - 1
Step-by-step explanation:
First, to figure out which part of the graph to be looking at, you will look at the shaded region as the solution area.
So, the solution area is to the left of the line. Said line is a dotted line which means that the points on the line can not be a solution.
If the points on the line can not be a solution then it eliminates answer choices C and D because y can not equal the other side of the inequality.
Now, we will bring the shaded region back into focus to find out if y is greater than or less than the other side. The shaded area is "below" the line so it is less than -2x - 1.
To ensure this is correct, plug two points into the inequality we just chose, one from the shaded region and one not, just to make sure the answer is correct.
I picked (-3,4) to test. So plug them into the inequality to get:
4 < -2 (-3) - 1
So 4 < 6 - 1 which is correct.
Then from the other side of the line I picked (5,2)
2 < -2 (5) - 1
2 < -10 - 1
2 < -11 is not true so the inequality that we found was correct.
Definitely A, its direct fast and straight to the point the other ones seem extremely extra<span />
You would just break each one into 2 separate equations and solve for x/r. Then write the answer in between the two inequality signs- so the answers for 9 and 11 would look like this, just fill in the blanks with the answer you got: 3<span>≤____<5, 2>___>-2.
</span>
0<span>≤x-2<3
1</span><span>≤x-2 and x-2<3
</span><span>-1>2r-5>-9
-1>2r-5 and 2r-5>-9
this one just solve each one for z.
2z-1</span>≤5 or 3z-5>10
<span>z≤3 or x>5</span>
<span>greater than 3 AND less than 5, the intersection of the two sets is 4 and the probability of rolling a 4 is 1/6.</span>
