What is the value of the expression n(8n/10) when n = 5?

EASY POINTS!! HELP AND ILL MARK YOU BRAINLIEST!!!!

natali 33 [55]

Answer: (6, -30)

Step-by-step explanation:

Substitute the points into the equation:

3.5 = -1/2(1^3) - 3(1) + 7 = 3.5: (1, 3.5) is on the graph.

-60.5 = -1/2 (9^2) -3(9) + 7 = -60.5: (9, -60.5) is on the graph.

-1 = -1/2 (-8^2) -3(-8) + 7 = -1. (-8, -1) is on the graph.

-30 = -1/2(6^2) -3(6) + 7 = -29 (6, -30) is not on the graoh.

Two numbers are randomly selected on a number line numbered from 1 to 9. Match each scenario to its probability. Tiles the proba

Natalija [7]

Numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9

probability that both numbers are greater than 6 if the same number can be chosen twice.
3² / 9² = 9/81 or 1/9

the probability that both numbers are less than 7 if the same number can be chosen twice
6² / 9² = 36/81 or 4/9

the probability that both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice
3/9 * 2/8 = 6/72 or 1/12

the probability that both numbers are even numbers if the same numbers cannot be chosen twice
4/9 * 3/9 = 12/81 or 4/27

The figure below is an isosceles triangle. What is the perimeter of the triangle in terms of a

professor190 [17]

Hey there! I'm happy to help!

-------------------------------------------------------------------

WHAT IS THE PERIMETER?

The perimeter is just the distance around a shape. If you put a fence around a field, the length of all of the fencing is the perimeter.

-------------------------------------------------------------------

WHAT IS AN ISOSCELES TRIANGLE?

An isosceles triangle is a triangle that has at least two sides that have the same length! In our triangle, we have two sides that have the value of a, so that makes it isosceles!

-------------------------------------------------------------------

THE SOLUTION

In our problem, we want to find the perimeter of this triangle in terms of a and c. When we say in terms of, it just means that our answer will include a and c instead of finding a number value.

The perimeter is the sum of each of these sides. This means that the perimeter is a+a+c, which is also 2a+c.

Therefore, the perimeter of this isosceles triangle is 2a+c.

I hope that this helps! Have a wonderful day! :D

I WILL GIVE BRAINLIEST!!!! ~PLEASE HELP (all the answers for all the questions please for the second and first picture)

Answer:

Question 6: I know that (8 + 9) + 3 is equal to 8 + (9 + 3) because of the associative property states that you can change the grouping of addends in any order you want. The benefit to using this property is that you can first add numbers that you can combine more easily. For example, (743 + 51) + 49 can be written as 743 + (51 + 49) or 743 + 100. It is more straightforward to add the numbers that equal 100 first and then add the final number.

Question 3: -3(4x + 3) + 5x [Given]; -12x - 9 + 5x [Distributive Property]; -12x + 5x - 9 [Commutative Property]; -7x - 9 [Combine like-terms]. $\frac{1}{2}$ (6k + 10) + 5k [Given]; 3k + 5 + 5k [Distributive Property]; 3k + 5k + 5 [Commutative Property]; 8k + 5 [ Combine like-terms].

Question 4: 4(2 - 5) - 8 = 4 * (-3) - 8 = -12 - 8 = -20; 4 * 2 - 28 = 8 - 28 = -20.

Question 5: 15 * 3 - 2(2 * 3 + 6) = 45 - 2(6 + 6) = 45 - 2(12) = 45 - 24 = 21; 11 * 3 - 12 = 33 - 12 = 21.
