Which inequality is graphed on the coordinate plane?

ruslelena [56]

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.

Ben earns 9 dollars per hour and 6 dollars for each delivery he makes.He wants to earn more than 155 dollars in a 8 hour work da

Luden [163]

9 x 8 = 72
155 - 72 = 83
83 divided by 6 =13.8

So he has to make at least 14 deliveries in order to reach his goal.

Answer: 7.5

Step-by-step explanation:

Line the numbers up in numerical order

0, 0, 0, 0, 0, 0, 0 , 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 32, 60, 92, 97, 100

Then find the middle number, since there is an even number there will be two middle number, those numbers are 8 and 7

You then divide 8 add 8+7 and divide by 2

which is 7.5

Answer:

B: BC ≅EC

Step-by-step explanation:

You know that the two angles starting in C are congruent (they're opposite by vertex C).

Given that the B angle and the E angle are congruent, in order for the two triangles to be congruent by A(ngle)S(ide)A(ngle) you want the side inbetween to be congruent. That is BC and EC. Option B
