$x - 2y=5$

Step-by-step explanation:

Given

$x = -5; y=-5$

$x - 2y$ --- missing from question

Required

Evaluate

We have:

$x - 2y$

Substitute for x and y

$x - 2y=-5 - 2*-5$

$x - 2y=-5 +10$

$x - 2y=5$

Answer:

Option B

x ≥ (-5)

Step-by-step explanation:

<h3><u>Given</u>;</h3>

-3(x + 4) ≥ x + 8

So,

-3(x + 4) ≥ x + 8

-3x – 12 ≥ x + 8

Add both sides 12 we get,

-3x – 12 + 12 ≥ x + 8 + 12

-3x ≥ x + 20

Similarly, subtract x from both sides we get,

-3x – x ≥ x – x + 20

-4x ≥ 20

Then, divide both sides by (-4) we get,

-4x/(-4) ≥ 20/(-4)

x ≥ -5

Thus, The answer is x ≥ (-5).

Simplify using exponents: B12/B5

stiks02 [169]

I think what you mean is:
$\frac{b^{12}}{b^{5}}$

Then using our rules of exponents, this is the same as
$b^{12-5}=b^{7}$

3 3Cylinder A 3 3 4 4Cylinder B 2 2 What is the ratio of the volume of Cylinder A to the volume of Cylinder B? Choose 1 answer:

frutty [35]

Answer:

(D) $\dfrac{27}{16}$

Step-by-step explanation:

Volume of a Cylinder = $\pi r^2h$

<u>Cylinder A</u>

Height = 3 Units

Radius = 3 Units

$Volume =\pi \times 3^2 \times 3 =27\pi$ cubic units$

<u>Cylinder B</u>

Height = 4 Units

Radius = 2 Units

$Volume =\pi \times 2^2 \times 4 =16\pi$ cubic units$

$\dfrac{\text{Volume of Cylinder A}}{\text{Volume of cylinder B}}=\dfrac{27\pi}{16\pi}\\\\=\dfrac{27}{16}$

The correct option is D
