Answer:

A. Division Property of Equality

Step-by-step explanation:

2x + 5 = -4(x + 5)\\

Using Distributive Property in -4(x + 5)

2x + 5 = -4x - 20\\

Using Subtraction Property, subtracting -5 in both sides

2x = -4x - 25\\

Using Addition Property, adding 4x in both sides

6x = -25

Now, using the Division Property of Equality, dividing both sides by 6

$x =- \frac{25}{6} $

The probability that the first slice of the cake will have the marble exists

7/66.

<h3>How to determine the probability using parts A and B?</h3>

Part A of the question demands that the volume of the cake be

estimated.

The volume of the cake exists, $V=\pi(\frac{d}{2} )^{2} h \\

$&V=\pi(\frac{9}{2} )^{2} * 4

$V=81 \pi

The part B of the question requires that the volume of each cut be

computed

The volume of each cut exists, V = 27

To estimate the required probability

We simply divide the volume of each cut by the volume of the cake.

$P=\frac{27}{81 \pi}

$P=\frac{1}{3 \pi}

Expand $\pi$

$&P=\frac{7}{3 * 22} \\

$&P=\frac{7}{66}

Therefore, the probability that the first slice of the cake will contain the

marble exists at 7/66.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4)?
Korolek [52]

Answer:

y=-5/2x-1

Step-by-step explanation:

first find the gradient whereas since the two lines are parallel they hav the same gradient. y=mx+c whereas m is the gradient. 5x+2y=12

2y=-5x+12

y=-5/2x+12(so the gradient is -5/2x..... <u>g</u><u>r</u><u>a</u><u>d</u><u>i</u><u>e</u><u>n</u><u>t</u><u>=</u><u>-</u><u>5</u><u>/</u><u>2</u>

<u>y</u><u>-</u><u>4</u>=-5/2

x+2

y-4=-5/2(x+2)

y-4=-5/2x-5

y=-5/2x-5+4

y=-5/2x-1

What is the value of k?
Molodets [167]

Answer:

( {x}^{2}  + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2}  - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12
