Answer:

-10

Step-by-step explanation:

1. Write it out.

x+8=-2

2. Get x by itself.

To do this, we have to move the 8, but to do that that we have to move it to the other side of the equation. Because the opposite of addition is subtraction, we have to subtract 8 by both sides. x+8=-2

-8 -8

x=-10

And that's the answer! Hope this helped :)

A sphere has a diameter of 14.5 inches.

dlinn [17]

Answer:

≈ 660.5 in²

Step-by-step explanation:

The surface area (A) of a sphere is calculated using the formula

A = 4πr² ← r is the radius

Given diameter = 14. 5 then radius = 7.25, thus

A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²

Complete the table below to solve the equation 2.5x − 10.5 = 64(0.5x).

nydimaria [60]

Answer:

Step-by-step explanation:

western beach: y = -2x + 100

dunes beach : y = 5x + 20

set the equations equal to each other

-2x + 100 = 5x + 20

100 - 20 = 7x

80 = 7x

80/7 = x

x ~ 11.43 years

How is the graph of y =(x-1)2 - 3 transformed to produce the graph of y = 5(X+4)??

lina2011 [118]

Answer:

<h2>The graph is translated left 5 units, compressed vertically by a factor of 5, and translated up 3 units.</h2>

Step-by-step explanation:

The initial function is

$y=(x-1)^{2} -3$

The transformed function is

$y=5(x+4)^{2}$

Notice that the first function represents a parabola with vertex at (1, -3), and the secong function represents a parabola with vertex at (-4, 0). That means the function was shifted three units up and 5 units to the left. Additionally, the function was compressed by a scale factor of 5, because that's the coffecient of the quadratic term.

Therefore, the right answer is the first choice.
