X= 4y - 2 x - 3y = 6 if you were going to solve this equation by substitution, what would your first step look like?

4y-2-3y=6 = y=8

y=4 * 8 - 2

= x=30

answer is y=8, x=30

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
