Answer: Statistical Analysis System

Step-by-step explanation:

Answer:

Part A: The percent discount on game is 20%.

Part B: Mario paid a total of $28.50 including sales tax.

Step-by-step explanation:

Given that:

Part A:

Original price of video game = $32.99

Discounted price = $26.39

Amount of discount = 32.99 - 26.39 = $6.60

Discount percent = [tex]\frac{Amount\ of\ discount}{Original\ price}*100[/tex]

Discount percent = [tex]\frac{6.60}{32.99}*100 = 0.20*100[/tex]

Discount percent = 20%

Part B:

Sales tax = 8% of discounted price

Amount of sales tax = [tex]\frac{8}{100}*26.39 = 0.08*26.39[/tex]

Amount of sales tax = $2.11

Total amount = $26.39 + $ 2.11 = $28.50

Hence,

Part A: The percent discount on game is 20%.

Part B: Mario paid a total of $28.50 including sales tax.

As table shows a proportional relationship between x and y then constant of proportionality are 20, 40, 0.2 and 20 respectively

In the first table, the constant of proportionality is 20 because each value of y is obtained by multiplying the corresponding value of x by 20.

In the second table, the constant of proportionality is 40 because each value of y is obtained by multiplying the corresponding value of x by 40.

In the third table, the constant of proportionality is 0.2 because each value of y is obtained by multiplying the corresponding value of x by 0.2.

In the fourth table, the constant of proportionality is 20 because each value of y is obtained by multiplying the corresponding value of x by 20.

Answer: y = 6; x = 12

Step-by-step explanation:

3x - 30 = y

Change this into an equation where x and y are in the same side.

3x - 30 = y

Subtract y from both sides

3x - y - 30 = 0

Add 30 to both sides

3x - y = 30

7y - 6 = 3x

Do the same thing I did to the first equation

7y - 6 = 3x

Subtract 3x from both sides

-3x + 7y - 6 = 0

Add 6 to both sides

-3x + 7y = 6

We can now use the system of elimination to find x and y.

3x - y = 30

-3x + 7y = 6

After adding both equations, you get:

6y = 36

Divide 6 from both sides

y = 6

Since we now know y, we can solve for x.

3x - 30 = y

Substitute y for 6

3x - 30 = 6

Add 30 to both sides

3x = 36

Divide both sides by 3

x = 12

Hope this helped!

Answer:

Answer:

HJ + JM = 5

Step-by-step explanation:

The number line is majorly used to show the positions of directed numbers. For the given question, the number line has the required points as shown in the attachment to this answer.

From the number line,

HJ = -1 - (-3)

    = -1 + 3

    = 2

HJ = -2

JM = 2 - (-1)

     = 2 + 1

     = 3

Thus,

HJ + JM = 2 + 3

              = 5

HJ + JM = 5

Answer:

$1000 ; 500 ; 1000 ; y = 500x + 1000

Step-by-step explanation:

From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.

The slope :

x1 = 0 ; y1 = 1000

x2 = 6 ; y2 = 4000

Slope = Rise / Run

Rise = y2 - y1 = 4000 - 1000 = 3000

Run = x2 - x1 = 6 - 0 = 6

Hence,

Slope = 3000 / 6

Slope = 500

y - intercept = 1000 (from. Graph)

Equation in slope intercept form:

General form : y = mx + c

m = slope ; c = intercept

Equation is written as ;

y = 500x + 1000

Step-by-step explanation:

Here, we want to show that the left hand side equals the right hand side

We can express the left hand side as:

sin A/ cos A * sec A/cosec A

kindly recall that;

sin A/cos A = tan A

Also;

sec A = 1/ cos A

cosec A = 1/ sin A

Thus, we have that ;

tan A * 1/cos A / 1 / sin A

= tan A * sin A/cos A

This is;

tan A * tan A = tan^2 A

The third choice, [tex]x\leq -8[/tex]

Step-by-step explanation:

One way to do it is to substitute in the potential answers. I'll show you here.

Choice 1

[tex]2(-2)+3\leq (-2)-5[/tex]

[tex]-4+3\leq -2-5[/tex]

[tex]-1\leq -7[/tex]

We can see that this is false, so the answer cannot be choice 1.

Choice 2

[tex]2(2)+3\leq (2)-5[/tex]

[tex]4+3\leq 2- 5[/tex]

[tex]7\leq -3[/tex]

This is also false, so the answer cannot be choice 2.

Choice 3

[tex]2(- 8)+ 3\leq (-8)-5[/tex]

[tex]-16+3\leq -8-5[/tex]

[tex]-13\leq -13[/tex]

This is true. Let's see if choice 4 works.

Choice 4

[tex]2(8)+3\leq (8)-5[/tex]

[tex]16+3\leq 8-5[/tex]

[tex]19\leq 3[/tex]

This is not true. Therefore, 3 is correct.

Hello! (:

y=2x-5

This equation is written in slope-intercept form (y=mx+b)

Where

m is the slope of the line (2)

b is the y-intercept (5)

Hope it helps! Please ask if you have any query.

~An excited gal

[tex]MagicalNature[/tex]

The slope of the line y = 2x + 5 is 2 obtained by comparing it with slope intercept form y=mx+b, where m is slope.

The slope represents the rate at which the line is increasing or decreasing as you move along the x-axis.

The slope of a linear equation in the form y = mx + b is represented by "m."

In this case, "m" is 2, which means the slope of the line y = 2x + 5 is 2.

Since the slope is positive (2), it means that as x increases by 1 unit, y increases by 2 units, and as x decreases by 1 unit, y decreases by 2 units.

The slope of 2 indicates that the line is inclined, and it rises at a steady rate of 2 units for every 1 unit moved to the right along the x-axis.

Hence, slope of the line  y = 2x + 5 is 2.
