f(x) = 2(3x)
Exponential functions represent the initial value outside of the parentheses so if 2 is the initial value it has to be on the outside of the parentheses.
Exponential growth formula.
 $y=a(1+r)^{x}$
a represents the initial value.

Simplify the following expression. 1/4 (24-16x) a. 6+4x b. 6+4 c. 6-4x d. 6-4

adoni [48]

Answer is 6-4x

1/4 evaluates to 1/4

Multiply x and 16

Multiply x and 1

after you have the answer it should come out to 24-16x then multiply 1/4 * 24-16x

1/4 *24=6

1/4*(24-16*x) evaluates to 6-4x

Identify the form of each equation. 7x + 5y = 8 is in (select) . y − 5 = 3 (x − 9) is in (select) . y = 7x + 9 is in (select) .

erik [133]

Answer:

Let's define all the possible forms:

slope-intercept: y = a*x + b

point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)

standard form: a*x + b*y = c

then:

a) 7x + 5y = 8

This is in standard form.

b) y − 5 = 3*(x − 9)

This is in point slope form.

c) y = 7x + 9

This is in slope-intercept form.

d) 8x − 9y = −2

This is in standard form.
