Answer:

D) This is a reflection because triangle ABC has been flipped over the x-axis.

Step-by-step explanation:

You can see that A'B'C' is congruent to ABC

You can also confirm the fact that it is a reflection by counting the distance from a point to the X axis and comparing it to the corresponding point- for example, A is 2 units above the X axis, and A' is 2 units below.

Answer:

Step-by-step explanation:

The Y-axis is the up and down part so if the Triangle was flipped on the Y-axis then it would be facing down and the diagrams would match

Your time spent playing pool and ice skating must not exceed 20 hours a week. Your weekly allowance is $80. You pay $3 an hour p

Anton [14]

Answer:

The graph in the attached figure

Two possible solutions are the point (10,10) and the point (4,8)

see the explanation

Step-by-step explanation:

Let

x ----> the time in hours spent playing pool in a week

y ----> the time in hours spent for ice skating in a week

we know that

$x+y \leq 20$ ----> inequality A

$3x+5y \leq 80$ -----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that the time can not be a negative number

If a ordered pair is a solution of the system of inequalities, then the ordered par must lie on the shaded area of the solution

Looking at the graph

Two possible solutions are

(10,10) ----> this point lie on the shaded area of solution

That means -----> The time in hours spent playing pool in a week is 10 and the time in hours spent for ice skating in a week is 10

(4,8) ----> this point lie on the shaded area of solution

That means -----> The time in hours spent playing pool in a week is 4 and the time in hours spent for ice skating in a week is 8

The spinner below is spun three times, find all possible outcomes. the spinner has 12 numbers

Simora [160]

For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

<h3></h3><h3>What is the combination?</h3>

A combination is a mathematical technique that determines the number of possible arrangements.

Let's we have to define

A, B, and C, as the regions in the spinner.

So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:

The outcome of spin 1, the outcome of spin 2, outcome of spin 3.

The total number of different outcomes will be:

3^3 = 27

4. 1 less than twice the square of a number

givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D
