The answer for what is NOT true would be..

B. A sequence is a function whose domain is the set of real numbers.

C. A function is a relation in which each value of the input variable is paired with exactly one value of the output variable.

I hope this helps have a great day.

(Angle/triangle problem 25points)<br> What is the value of X?

Serhud [2]

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the triangle and equate to 180, that is

10x - 4 + 8x + 3 + 91 = 180

18x + 90 = 180 ( subtract 90 from both sides )

18x = 90 ( divide both sides by 18 )

x = 5

D) - 15/3 = x + 1<br> how do i solve this

kobusy [5.1K]

Answer:

x = - 6

Step-by-step explanation:

- 15/3 = x + 1

- x = 1 + 15/3

- x = 3/3 + 15/3

- x = 18/3

x = - 18/3

x = - 6

Which of the following is a solution to the differential equation xy′−3y=6 ?

ololo11 [35]

Answer:

$y = 5 {x}^{3} - 2$

Step-by-step explanation:

The given differential equation is :

xy′−3y=6

We want to determine which of the following options is a solution to the differential equations.

The function that satisfies the differential equation is a solution.

We can verify that

$y = 5 {x}^{3} - 2$

satisfy this differential equation.

We differentiate to get:

$y' = 15 {x}^{2}$

We substitute the function and its derivative into the differential equation to get:

$x(15 {x}^{2}) - 3(5 {x}^{3} - 2) = 6$

We expand and simplify on the left:

$15 {x}^{3}- 15 {x}^{3} + 6= 6$

This simplifies to:

$6 = 6$

Verified.

We can show that all the other functions do not satisfy this differential equation
