-1/4 ( 12x + 8) is less than or equal to -2x + 11 what is the solution to this inequality

Answers

Answer:

X greater or lesser than -13

Step-by-step explanation:

To find the solution to this inequality, solve for x.

-1/4 (12x + 8) ≤ -2x + 11

First, distribute -1/4 into (12x + 8)

-3x - 2 ≤ -2x + 11

To solve for x, bring it to one side of the equation

-x - 2 ≤ 11

Add 2 to both sides to isolate x

-x ≤ 13

Divide each side by -1

x ≥ -13

When you divide by a negative sign with an inequality, you flip the inequality sign. So negative x is less than or equal to 13 becomes x is greater than or equal to -13.

To check this, plug in -13 for x, a number greater than -13 for x, and a number less than -13 for x. The solution will be true for a number ≥ -13, but false for a number ≤ -13

D. She should have added the values, not subtracted them.

Answers

Answer:

C. She did not keep the order of the points the same in the numerator and the denominator.

Step-by-step explanation:

She needs to switch 1 with 17 so it can be [tex]\frac{17-1}{18-14}[/tex]. It needs to equal [tex]\frac{y2-y1}{x2-x1}[/tex].

Answer:

C. She did not keep the order of the points the same in the numerator and the denominator.

Step-by-step explanation: Hope this helps

The correct slope should look like: 1-17/14-18

If you do 1-17 for the numerator then 14-18 must be the denominator (the slope is 4: -16/-4 = 4)

The equation to find the slope of a line is (y2-y1)/(x2-x1). (x1,y1) is the first coordinate point, (x2, y2) is the other. It does not matter which coordinate point you use first, as long as you remain consistent.

Nyla invested $200 in an account with a 0.75% annual interest rate.
She made no deposits or withdrawals on the account for 3 years. If
interest was compounded annually, what is the balance in her bank
account at the end of 3 years?
A=4.53

B=1,071.88

C=450.00

D= 204.53

Answers

Answer:

Step-by-step explanation:

.75% of 200 is 1.5

multiply that by 3

add the original amount

The $204.53 is the balance in her bank account at the end of 3 years option (D) 204.53 is correct.

It is given that the Nyla invested $200 in an account with a 0.75% annual interest rate.

It is required to find the balance in her bank account at the end of 3 years if compounded annually.

What is compound interest?

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A= P(1+r)^t[/tex]

Where A = Final amount

P = Principal amount

r = annual rate of interest

t = How long the money is deposited or borrowed (in years)

We have P = $200

r = 0.75% = 0.0075

t = 3 years

Putting the values in the formula, we get;

[tex]\rm A= 200(1+0.0075)^3\\\\\rm A = 200(1.0226)\\\\\rm A = \$204.52[/tex]

or A ≈ $204.53

Thus, the $204.53 is the balance in her bank account at the end of 3 years option (D) 204.53 is correct.

Homework, sports, jobs, and social activities all compete for students after-school hours, which often extend late into the night. The reality, then, is that most teens do not get enough sleep.
