Which inequality is graphed on the coordinate plane?

Mathematics
1 answer:
ruslelena [56]3 years ago

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.

When adding or subtracting fractions, there is one big rule: make sure the denominators are the same first!

As long as the denominators (the numbers on the bottom of the fraction) are the same, you can get an answer by adding the numerators (the numbers on top) and keeping the denominator the same.

********Here's an example********

2/3 + 3/3

First, make sure the denominators are the same. Since the number on the bottom of each fraction is the same, namely 3, we can proceed without worry.

Now add the numerators. The numbers on top are 2 and 3. 2 + 3 = 5.

The final answer is 5/3. We added together the numerators to get the top number, and kept the denominator the same for the bottom number.

***************************************

Try adding 3/4 and 4/4 together on your own now before you look ahead.

To get the answer, let's follow the process.

Make sure the denominators match. They do, so we can proceed.

Add the numerators. 3 + 4 = 7.

Keep the denominator the same. The denominator is 4.

Your answer is 7/4!

Do you have any other questions about the process? Was this helpful?

Keep on working! you got this!

Solve for ddd. 6d-\dfrac{11}2=2d-\dfrac{13}26d− 2 11 ​ =2d− 2 13 ​ 6, d, minus, start fraction, 11, divided by, 2, end fraction,
ANEK [815]

Answer:

d = -\dfrac{1}{4}

Step-by-step explanation:

Given

6d-\dfrac{11}2=2d-\dfrac{13}{2}

Required

Solve for d

6d-\dfrac{11}2=2d-\dfrac{13}{2}

Collect Like Terms

-2d + 6d=-\dfrac{13}{2}+\dfrac{11}{2}

4d=-\dfrac{13}{2}+\dfrac{11}{2}

Take LCM

4d=\dfrac{-13+11}{2}

4d=\dfrac{-2}{2}

4d = -1

Make d the subject

d = -\dfrac{1}{4}

jeka57 [31]

Answer:

About 13% of the freshman class are left-handed

Step-by-step explanation:

To find the percentage of a whole you need to divide the part by the whole number (85/645 = 0.1316), then you round to the nearest tenth (0.13) and change it into a percentage by moving the decimal point 2 numbers to the right. (13%)
