6(x+2) = 6x + 12
3(x-9) = 3x - 27

6x + 12 + 3x - 27 = 9x - 15

The answer is 9x - 15

6(x + 2) + 3(x - 9)

6(x + 2) = 6 * x = 6x , 6 * 2 = 12
6x + 12

3(x - 9)= 3 * x = 3x , 3 * -9 = -27
3x - 27

6x + 12 + 3x - 27=

6x + 3x = 9x
12 - 27 = -15

Answer: 9x - 15

Find the zeros of f(x) =x^3+2x^2-3x

lora16 [44]

Answer: 0, 1, -3

Step-by-step explanation:

f(x) = x^3 +2x^2 -3x

f(x) = x(x^2 +2x-3)

f(x) = x(x-1)(x+3)

to find zeroes, plug into f(x) and solve for each value of x. doing this gives 0, 1, and -3

What is the domain of the function y=-720t + 3600 ?

Colt1911 [192]

Answer:

We conclude that:

$\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Please also check the attached graph.

Step-by-step explanation:

Given

Given the function

$y=-720t\:+\:3600$

To determine

What is the domain of the function y=-720t + 3600

We know that the domain of the function is the set of input argument values for which the function is real and defined.

Given the function

$y=-720t\:+\:3600$

From the given function, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain of the function is

$-\infty \:$

Thus, we conclude that:

$\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$
