Answer:

-11x-5x^2+5x^3

Step-by-step explanation;

8x^3-x-10x+5x^2+3x^3 (distribute the negative sign)

8x^3-3x^3    -x-10x (combine like terms)

5x^3-11x-5x^2

-11x-5x^2+5x^3 (put in Standard form)

Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds. What is the domain? {t| 0 ≤ t ≤ 3} {t| 0 ≤ t ≤ 48} {t| 0 ≤ t ≤ 64} {t| all real numbers

Answers

Answer: t 0<t<3

Step-by-step explanation:

Answer:

The correct option is 1.

Step-by-step explanation:

The given graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.

The value of height and time can not be negative, there the values of h and t must be greater than 0.

The set of all possible inputs is called domain. In the graph x axis represent the domain and y-axis represent the range.

The graph is defined from t=0 to t=3.

Therefore option 1 is correct.

What is LaTeX: m\angle PTQm ∠ P T Q?

line ps intersecting with line qr at point t. angle ptq is x + 28 degrees. angle rts is 2x + 16 degrees.

Group of answer choices

140

40

50

12

Answers

Answer:

B. 40

Step-by-step explanation:

If line ps intersecting with line qr at point t as shown, then ∠ P T Q = ∠RTS (oppositely directed angle)

Given

PTQ is x + 28

RTS is 2x + 16

Since they are both equal, then x+28 = 2x+16

collect like terms

x-2x = 16-28

-x = -12

multiply both sides by -1

-1(-x) = -1(-12)

x = 12

Since ∠ P T Q = x+28, substitute x = 12 into the function

∠ P T Q = 12+28

∠ P T Q = 40

Hence measure of ∠ P T Q is 40°

Step-by-step explanation:

Answer:

Step-by-step explanation:

It is 5a² because 7a² and 2a² are like terms, so we are able to subtract them. If we subtract 7-2 we get 5. It is the same thing, 7a²-2a² is equal to 5a²

It's a bit hard to explain, in my opinion. but I'll give it a go. Lets say you have 10 full pizzas, and you want to split it upon 5 people. Now 5 2 slices is 10, like 5x2 so basically, it's kind of like backwards multiplying. if that makes sense. Think of it like this. if you see something like 14 ÷ 2,  think of what number times 2 would be 14. 7, exactly. So Just write the number thats missing. Thats how i like to think of it. What number is missing.
