Answer:

The missing value is 5

The solution is (8,5)

Explanation:

The given equation is:

5x - 2y = 30

An order pair is written as (x , y). We are given (8 , ?)

This means that we want to find the y value that corresponds to x=8

To do this, we will substitute with x=8 in the given equation and solve for y

This is done as follows:

5x - 2y = 30

5(8) - 2y = 30

40 - 2y = 30

2y = 10

y = 5

This means that at x=8 and y=5, the equation is satisfied

(8,5) is a solution to the given equation

Hope this helps :)

Answer:

(8, 5)

Step-by-step explanation:

The given equation is:

5x - 2y = 30

We have to complete the given incomplete solution set (8, ?)

The first point in the ordered pair is always the x-value. So we are given an x-value and we have to find the corresponding y-value from the function.

Using x = 8 in the given function, we get:

5(8) - 2y = 30

40 - 2y = 30

- 2y = 30 - 40

- 2y = -10

y = 5

So, the value of y for x = 8 is 5. The complete ordered pair that satisfy the equation will be (8, 5)

Subtract 3 from both sides:

7r = 56

Divide both sides by 7:

r = 8

Answer:

r = 8

Step-by-step explanation:

59 = 7r+3

subtract both sides by 3

56 = 7r

divide both sides by 7

8 = r

In order to answer 23, you have to include 22 in the picture. The answer to 24 is 3 times 11+6, and Kayla earns $351.

Step-by-step explanation:

Answer: $351

Step-by-step explanation:

f(x) = 3x + 6                 g(x) = x - 2

(f · g)(x) = (3x + 6)(x - 2)

             = 3x² - 6x + 6x - 12

             = 3x² - 12

(f · g)(11) = 3(11)² - 12

              = 3(121) - 12

              = 363 - 12

              = 351

The graph of the circle is given in the image attached

To graph the circle represented by the equation x^2 + (y+3)^2 = 9, identify the center at (0,-3) and radius 3, then plot the center and draw the circle on a graph.

The student's question relates to the equation of a circle in Cartesian coordinates and how to graph it. Given the equation x2 + (y+3)2 = 9, we can determine the center and the radius of the circle it represents. To graph the circle, first identify the center, which in this case is at (0, -3), because the equation can be written in the standard form (x - h)2 + (y - k)2 = r2 where (h, k) is the center and r is the radius. Then find the radius by taking the square root of the right side of the equation, which is 3 in this case.

Plot the center on the Cartesian graph, and draw a circle around it with a radius of 3 units, ensuring that possible points on the circle follow the equation such as (0,0), (-3,-3), and (3,-3) for instance.

The graph that represents the line (y = 12x) is option C) and this can be determined by using the point-slope form of the line.

Given :

Bike traveling at a constant rate of 12 miles per hour.

The following steps can be used to determine the graph that represents a bike traveling at a constant rate of 12 miles per hour:

Step 1 - All the graphs in the option pass through the point (0,0). So, (0,0) is the point through which a line is pass through.

Step 2 - Another point is (1,12) through which line passes because it is given that bike traveling at a constant rate of 12 miles per hour.

Step 3 - The equation of the line that passes through the points (0,0) and (1,12) is given by:

[tex]\dfrac{y-0}{x-0}=\dfrac{12-0}{1-0}[/tex]

y = 12x

So, the graph that represents the line (y = 12x) is option C).

The answer is P(0,4) , Q(2,0)

Step-by-step explanation:

Points P and A are any coordinates where y = 4 - 2x. For example, P might be the point (1, 2).

The given equation is 4x + 2y = 8. To find the coordinates of points P and A, we can rearrange and simplify the linear equation. Divide the whole equation by 2, we get 2x + y = 4, or y = 4 - 2x. Therefore, the line has the slope-intercept form of y = mx + b, where m is the slope and b is the y-intercept. This line passes through all points (x, y) where y = 4 - 2x. Therefore, P and A can be any points satisfying this equation. For example, if x = 1, then y = 2, so one possible coordinate is P(1, 2).

To simplify the expression 7√5-3√80, the second term is broken down and then subtracted from the first term, resulting in the final simplified answer of √5.

To simplify the expression 7√5-3√80, we should first break down the second term, 3√80, into simpler terms.

The second term can be rewritten as 3√(4*20), since 4*20 = 80. Then this can be further broken down into 3√(4*4*5) which equals 3*2√5. In other words, 3√80 equals 6√5.

So, the original expression, 7√5-3√80, can now be rewritten as 7√5 - 6√5.

Since these two terms share the same radical, √5, you can subtract them just like you would subtract regular numbers. So, 7√5 - 6√5 equals 1√5, which simplifies further to √5.

To simplify the given expression, we simplify the square roots and combine like terms. The expression simplifies to -5√5.

To simplify the expression 7√5-3√80, we need to simplify the square roots.

The square root of 5 cannot be simplified further, but the square root of 80 can be simplified as the square root of 16 times the square root of 5.

Therefore, the expression becomes 7√5 - 3√16√5.

The square root of 16 is 4, so the expression simplifies to 7√5 - 3(4)√5. Continuing to simplify, we get 7√5 - 12√5.

Combining the like terms, we have (7-12)√5, which simplifies to -5√5.

To find the price of the video game with the coupon, subtract the discount amount from the original price.

To calculate the price of the video game with the coupon, we first calculate the discount amount. The coupon is for 25% off, so the discount amount is 25% of $100. Using the formula discount = (percentage / 100) * original price, the discount amount is (25 / 100) * $100 = $25.

To find the price of the video game with the coupon, we subtract the discount amount from the original price. The price of the video game with the coupon is $100 - $25 = $75.

Therefore, the price of the video game with the coupon is $75.

Answer:

15 < n < 25

Step-by-step explanation:

According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the possible length of  the 3rd side given other two sides (let two given sides be x and y), we can say that the 3rd side length will be between x+y and x-y.

Hence, we can say that n should be between 20+5 and 20-5.

So, 20 - 5 < n < 20 + 5, which is

15 < n < 25

This is the correct answer.
