Answer:

4071.5 in^2

Step-by-step explanation:

The surface area of a sphere of radius r is A = 4πr²

What are the slope and y-intercept for the graph of y – 3x = -1?
Liula [17]

Answer:

Slope (m) = 3, y-intercept (b) = -1

Step-by-step explanation:

First, we need to write the equation in y = mx + b.

To do this, add 3x to both sides.

y = 3x - 1 is your result.

Now, we have everything we need to do determine our slope and y-intercept in just this equation alone.

Remember, m = slope and b = y-intercept.

In this equation:

m = 3

b = -1

So your slope is 3, and your y-intercept is -1

Identify the solution(s) of the system of equations, if any. -4x-2y=16 2y=-4x-16
Elodia [21]
-4x-2y = 16
2y = -4x-16

Get one variable alone on both equations

-4x - 16 = 2y
-4x - 16 = 2y

You'll realize that they're the same equation.
Use substitution

-4x-16 = -4x-16
0 = 0
x = all solutions

Use x = all solutions in an earlier equation to find y

-4x - 16 = 2y
SInce x can be all solutions y is also all solutions
y = all solutions

What number must be added to the expression below to complete the square? x^2-9x
pantera1 [17]

Answer:

A.81/4

Step-by-step explanation:

x^2-9x

This is in the form x^2 + bx

To complete the square, we take b/2  then square it and add it

b =-9

b/2 = -9/2

(b/2) ^2 = (-9/2) ^2 = 81/4
