A function is a set of ordered pairs where a x-value is paired with only one y-value.

As long if the x-value (1) is sharing only one y-value then it makes it a function.

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:

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

Divide using synthetic division: (2x^4+2x^3+-12x^2+x+6)/(x+3)

kap26 [50]

Synthetic division yields

..... || 2 2 -12 1 6

-3 || -6 12 0 -3

= = = = = = = = = = = = = =

..... || 2 -4 0 1 3

which translates to

$\dfrac{2x^4+2x^3-12x^2+x+6}{x+3}=2x^3-4x^2+1+\dfrac3{x+3}$

A line passes through the point (-7,8) and has a slope of 1

Mila [183]

Answer:

y - 8 = x + 7

Step-by-step explanation:

To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).

$y - y_1 = m(x-x_1)\\y - 8 = 1(x --7)\\y - 8 = 1(x + 7)\\y - 8 = x+7$

Austin is on his way home in his car. His drive is 30 miles long. He has finished five-sixths of the drive so far. How far has h

drek231 [11]

30 miles is two-thirds of x (where x is the total distance)

30 = (2/3)*x 

30*3 = 2x
90 = 2x

90/2 = x

45 = x

x = 45

The total length of his drive is 45 miles
