1.1     Pull out like factors :

  -8x - 2  =   -2 • (4x + 1)

2.1    Divide both sides by  -2

Remember to flip the inequality sign:

2.2    Divide both sides by  4  

     x+(1/4)  ≥ 0

Solve Basic Inequality :

2.3      Subtract  1/4  from both sides

           x ≥ -1/4

Answer:

The answer is D.

Step-by-step explanation:

Divide both sides by -8 to get x by itself.

-8x  ≤ 2

-8x/-8 = x

2/-8 = -0.25

What you're left with is x  ≤ -.25

Since you divided you have to switch the signs.

x ≥ -.25

frosja888 [35]

Answer:

$ 31050

Step-by-step explanation:

<em>Step 1 : Write the formula for calculating simple interest.</em>

Simple Interest = <u>P x R x T </u>

                                100

P: Principal Amount-The loan taken (30,000)

R: Interest rate at which the loan is give (6)

T: Time period of the loan in years-there are 12 months in 1 year. There are 7 months from May till June (7/12)

<em>Step 2: Substitute values in the formula</em>

Simple Interest = <u>30,000 x 6 x 7/12</u>

                                       100

Simple Interest = $1050

<em>Step 3: Calculate the amount due at maturity</em>

At the maturity or the end of the time period given, the original or principal amount of the loan has to be repaid along with the simple interest.

Amount at maturity = Principal Amount + Simple Interet

Amount at maturity = 30,000 + 1050

Amount at maturity = $31050

sasho [114]

Answer:

Step-by-step explanation:

Formula

V pi * r^2 * h

Givens

r = 3 m

h = 6 m

pi = 3.14 when used.

Solution

V = pi r^2 * h

V = pi * 3^2 * 6

V = 9 * 6 * pi

V = 54 * pi  Volume in terms of pi

V = 54*3.14 Volume using a value for pi

V = 169.56 to the hundred's place.
