Answer 1
Answer:

Answer:

Values shown below

Step-by-step explanation:

Values of Functions

Given f(x) as an explicit function of x, we can compute the values for x, by replacing them into the expression.

We have

\displaystyle f(x)=y=2-x^3\n\displaystyle f(-2)=2-(-2)^3= 2+8=10\n\displaystyle f(-1)=2-(-1)^3=2+1=3\n\displaystyle f(0)=2-0^3=2-0=2\n\displaystyle f(1)=2-1^3=2-1=1\n\displaystyle f(2)=2-2^3=2-8=-6

Victor drew a quadrilateral with no right angels and 4 sides of equal length. What quadrilateral could Victor have drawn ?

Answers

Answer:

Rhombus

Step-by-step explanation:

We are given that Victor drew a quadrilateral with no right angles and 4 sides of equal length.

We have to find that what type of quadrilateral Victor could have drawn

We know that

A quadrilateral in which four sides of equal length can be square or rhombus.

But in square all angles of square are right angles.But Victor draw a quadrilateral in which no right angles .Therefore, the quadrilateral drawn by Victor could be rhombus because in rhombus all sides of equal length but no right angles.

A square can be rhombus but rhombus can not be square .Hence, the quadrilateral drawn by Victor is a rhombus .
It is Rombus because it has no right angles but it has 4 equal sides.It looks like a square that's kind of bent

Which of the equations shown have infinitely many solutions?Select all that apply.
A 3x - 1 = 3x + 1
® 2x - 1 = 1 - 2x
© 3x - 2 =2x-3
D 3(x - 1) = 3x - 3​

Answers

The answer is D because if you distribute, you get: 3x-3=3x-3
And anything you plug in for X has the same solution on both sides of the equation

Answer:

D

Step-by-step explanation:

In order to have infinitely many solutions, the lines must be the same.

If we solve D by using the distributive property, we end up withe 3x-3=3x-3.

3x-3 and 3x-3 are the same lines and intersect infinitely many times, therefore the correct answer is D.

Sumalee won 40 super bouncy balls playing horseshoes at her schools game last night. Later, she gave two to each of her friends. She only has 8 remaining. How many friends does she have?

Answers

Before jumping into doing this problem, it is important to look at all the information's that have been made available in the question. Based on those given conditions the answer to the problem can be easily deduced.
Let us assume the number of friends Sumalee has = x
Then
2x + 8 = 40
2x = 40 -8
2x = 32
x = 32/2
x = 16
So Sumalee has 16 friends. There are numerous ways to get to the answer that is required to be found. This is the easiest and the shortest method. Hope i helped you.
To find this we are first going to SUBTRACT to see how many balls she gave ALL her friends in total:- 

40 - 8 = 32

Now we will divide to see how many friends she has. 

32 ÷ 2 = 16

Check your work:-

16 × 2 = 32

So, she has 16 Friends.

Hope i helped ya!!!!!!!!!!!!!

One day after shopping at a department store Lenny discovered that he only had $13 left and his wallet he had entered the store with $81 in his wallet which equations could be used to find how much money Lenny spent (x)
