Answer:

Domain: [0, 4]

Range: [0, 4]

Function? Yes

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, our x-values span from 0 to 4. Since both are closed dot, they are inclusive in the domain:

Interval Notation - [0, 4]

Inequality Notation - 0 ≤ x ≤ 4

According to the graph, our y-values span from 0 to 4. Since both are closed dot, they are inclusive in the range:

Interval Notation - [0, 4]

Inequality Notation - 0 ≤ x ≤ 4

Since we see that each x-value has a unique y-value and passes the vertical line test.

∴ the relation is a function.

Answer:

7 : 7  : 12 am

Step-by-step explanation:

This question pretty much requires us to obtain the lowest number that is common to all three times. The qay to obtain this is by finding the LCM of all three numbers.

This is given as;

48 = 2 × 2 × 2 × 2 × 3

72 =  2 × 2 × 2 × 3 × 3

108 =   2 × 2 × 3 × 3 × 3

The LCM is = 2 × 2 × 2 × 2 × 3 × 3 × 3 = 432 seconds.

Converting to minutes by dividing by 60, the time is = 432 ÷ 60 min = 7 min 12 sec

The next time they would change simultaneously is; 7am + 7 min 12 sec = 7 : 7  : 12 am

Answer:

4x+2=22

4x=22-2

4x=20

x=20/4

x=5

Answer:

x = 5

Step-by-step explanation:

First step - subtract 2 from both sides:

4x + 2 - 2 = 22 - 2 which simplifies to 4x = 20

Second step - divide both sides by 4:

4x ÷ 4 = 20 ÷ 4 which simplifies to x = 5

Answer:

Slope

Step-by-step explanation:

Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.

The glide reflection of the figure is given below. Therefore, option D is the correct answer.

Glide Reflection is a composition of transformations. In glide reflection, a translation is first performed on the figure then it is reflected over a line.

From the given figure, labelled the black triangle as A, B and C.

The coordinates of  triangle ABC are; A= (2,8) , B= (2,5) and C=(6,5)

To find the glide reflection image of the triangle ABC.

Given: The rule of translation is: (x, y)→(x, y-7) and the line of reflection is x= 1.

Now, apply the rule of translation to the black triangle, and we get;

A(2, 8)→(2, 8-7)=A'(2, 1)

B(2, 5)→(2, 5-7)=B'(2, -2)

C(6, 5)→(6, 5-7)=C'(6, -2)

Now, apply the rule of reflection over the line x =1.

That is, (x, y)→(-x+2, y)

A'(2, 1)→(-2+2, 1)=A''(0, 1)

B'(2, -2)→(-2+2, -2)=B''(0, -2)

C'(6, -2)→(-6+2, -2)=C''(-4, -2)

You can see the graph of the Glide reflection as shown below.

Therefore, option D is the correct answer.

Hi there! Your answer to the problem would be Store A..

Step By Step Explainaction:

So we know that store A’s boxes cost $6 for each 3 boxes, and store be cost 5$ for 2 boxes.

Divide 6 with 3 since you want to know how much one would cost. 6 divide 3=6. Let check again by doing multiplication. 3x2 is also 6. This means that the cost for each box for Store A would be 2$.

Store B is the same but dividing 5$ with 2. 2x2=4 but we need to know 5. But 1 is actually .5 or 50% of 2. So it would be 2.5 or 2 and a remainder of 1. Same things...

So it would be Store A that gives cheaper cost. $2>$2.5

Given:

To find: Which store has the better deal.

Answer:

In order to do so, we'll need to divide the cost by the number of boxes to retrieve the cost of 1 box. The store with the lowest price for 1 box will have the better deal.

Let's first see what a box costs in Store A.

[tex]\sf \dfrac{Cost}{Number\ of\ boxes}\ =\ Cost\ of\ one\ box\\\\\\\dfrac{6}{3}\ =\ 2[/tex]

At Store A, the cost of a box is $2.

Now let's see what a box costs in Store B.

[tex]\sf \dfrac{Cost}{Number\ of\ boxes}\ =\ Cost\ of\ one\ box\\\\\\\dfrac{5}{2}\ =\ 2.5[/tex]

At Store B, the cost of a box is $2.5.

Since the cost at Store B seems to be a slightly higher price, Store A has the better deal.

Hope it helps. :)
