how many even integers n satisfy the inequality | 2N - 1 | < 5?

Answers

Answer:

-2 is the answer

Step-by-step explanation:

There is only one even integer i.e 2 that satisfies the given inequality | 2N - 1 | < 5.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Inequality | 2N - 1 | < 5 which is given in the question.

The positive solution to inequality as :

⇒ 2N - 1  < 5

⇒ 2N < 5 + 1

⇒ 2N < 6

⇒ N < 3

Therefore, N = 2 i.e an even integer satisfies the inequality.

The negative solution to inequality as :

⇒ -(2N - 1)  < 5

⇒ (2N - 1)  > -5

⇒ 2N > -5 + 1

⇒ 2N > - 4

⇒ N > -2

Therefore, N = 2 i.e an even integer satisfies the inequality.

Therefore, only one even integer satisfies the given inequality | 2N - 1 | < 5.

whats the answer to 1+3x=-2(x+7)

Answers

Answer:

x = -3

Step-by-step explanation:

1+3x=-2(x+7)

Distribute

1+3x = -2x-14

Add 2x to each side

1+3x+2x = -2x+2x-14

1+5x = -14

Subtract 1 from each side

1-1+5x= -14-1

5x = -15

Divide each side by 5

5x/5 = -15/5

x = -3

Define a variable, set up an inequality, then solve.

Answers

Inequality = 2/5x + 175<500

Answer= 1625/2 or 812 1/2

Answer: Inequality: 175+2x/5 ≥ 500. He must make $812.5 or more in his paycheck

Step-by-step explanation:

175+2x/5 ≥ 500

2x/5 ≥ 500-175

2x/5 ≥ 325

2x ≥ 325*5

2x ≥ 1,625

x ≥ 1,625/2

x ≥ 812.5

Lets simplify both equations:

[tex]-6(2)-6+8(2)=-2[/tex]

Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.
