Answer: The perimeter of the flower box can be determined by adding up the lengths of all four sides. In this case, we can see that the width of the flower box is represented by the variable x in feet, and the height is given as 2(x+4). To find the perimeter, we need to add up the lengths of the top and bottom (2x) and the left and right sides (2(x+4)). So, the perimeter P(x) can be expressed as:

P(x) = 2x + 2(x+4)

Simplifying this expression:

P(x) = 2x + 2x + 8

P(x) = 4x + 8

So the perimeter of the flower box is 4x+8 feet, based on the width x in feet.

We have many distance formulas in a coordinate system that can be used to find the distance between two points, the distance between a point to a line, the distance between two parallel lines, and the distance between two parallel planes.

The Distance Formula is a useful tool for calculating the distance between two points that can be arbitrarily represented as points:

A (x1,y1) and B (x2,y2) are on the coordinate plane.

Distance between two points:

(x₁,y₁),(x₂,y₂)

d=√(x₂-,y₂)²,(x₁-y₁)²

Distance between three points:

(x₁,y₁,z₁),(x₂,y₂,z₂)

d=√(x₂-,y₂)²,(x₁-y₁)²+(z₂-z₁)²

At point (x₁,y₁) and a line ax+by+c=0 is

d=|ax₁+by₁+c|/√a²+b²

Answer:

Step-by-step explanation:

what do you not understand

Answer: The correlation coefficient (also known as Pearson's correlation coefficient or r) is a measure of the strength of the linear relationship between two variables. The value of the correlation coefficient ranges between -1 and 1, with a value of 1 indicating a perfect positive linear relationship, a value of -1 indicating a perfect negative linear relationship, and a value of 0 indicating no linear relationship.

In this case, the correlation coefficient that represents the strongest linear relationship is

0.9

The absolute value of the correlation coefficient measures the strength of the linear relationship, regardless of whether it is positive or negative. So, the absolute value of 0.9 and -0.3 are both 0.9. but as we are looking for the strongest linear relationship, the value of 0.9 is closer to 1 than -0.3 is and it indicates stronger positive relationship.

In summary, the closer the correlation coefficient is to 1 or -1, the stronger the linear relationship between the variables is. In this case, 0.9 has the strongest linear relationship of the given options.

Therefore , the solution to the given problem of linear equation comes out to be  we bought 6 videos and 3 CDs.

The term "linear" refers to any function that has the algebraic form y=mx+b. m is the y-intercept, while B is the slope. The previous sentence contains a two-variable linear equation since both y and y are factors. Equations involving two variables are called bivariate equations. y + z = 2 and 3z - 6 + x = 3 are two of the many applications for linear equations. The equation y=mx+b, where m stands for the slope and b for the y-intercept, is referred to as a linear equation. The formula is Y=mx+b, where m denotes the inclination and b the y-intercept.

Here,

A collection of equations will be constructed.

Let V = the number of videos purchased.

C will stand for the quantity of purchased CDs.

Since there are eight nephews in all, and each nephew received either a video or a CD, the sum of the numbers of movies and CDs is nine.

So V + C = 9.

We are also aware of how much each CD and film cost and how much money was wasted.

So 14.95V + 16.88C = 140.34

Here, let's experiment with substitution.

Let's just solve for V since it doesn't matter whichever variable we do it for. V = 9 - C

Therefore, replace "V" in the second equation with "9-C," and the result will be 134.55 - 14.95C + 16.88C = 140.34 1.93C = 5.79 C = 3

You can add C = 3 straight into either of the original equations, though I believe I know which one is simpler for you.

V + 3 = 9

V = 6

So we bought 3 CDs and 6 videos.

Therefore , the solution to the given problem of equation comes out to be  we bought 6 videos and 3 CDs.

The value of x calculated by using the Pythagorean theorem is equal to 6.

This can be found by using the Pythagorean theorem to solve for the length of side bc, which is the base of the triangle. By using the two given side lengths of 8 and 12, we can find that the length of the hypotenuse (bc) is equal to the square root of 8^2 + 12^2, which is equal to 16.

Since the base is divided into two equal parts, we can divide 16 by 2 and get 8. We then subtract the given length of 2x + 1 from 8 and get 7, which means x is equal to 6.

Considering the equation of an ellipse, it is found that the height of the tunnel 10 feet from the edge is of 14 feet.

The following is the equation for a horizontal ellipse of center with coordinates (h,k):

(x - h)²/a² + (y - k)²/b² = 1.

In relation to this issue, we have that:

The origin is where the center is.

Since the major axis is 70, 2a = 70 and a = 35.

The maximum height is 20, therefore b is equal to 20.

As a result, the ellipse's equation is as follows:

x²/35² + y²/20² = 1.

It is determined that x = 25 when the tunnel is 10 feet from the edge since 35 – 10 = 25; therefore, the height y is calculated as follows:

25²/35² + y²/20² = 1

0.51 + y²/20² = 1

y²/20² = 0.49

y² = 20² x 0.49

y =√(20² x 0.49)

y = 14 feet.

Answer:

For each service call cost of 20$ will be added to fixed cost of 3000$.

Step-by-step explanation:

The total cost for 1 month is the sum of the fixed monthly cost and the cost of all the service calls, so we can write the equation as:

y = 3000 + 20x

This equation is already in slope-intercept form, where "y" is the dependent variable, "x" is the independent variable, 3000 is the y-intercept (the point where the line crosses the y-axis, when x=0), and 20 is the slope of the line.

This equation can be interpreted as

Answer:

9 and 10

Step-by-step explanation:

x = 1st positive integer

x+1 = 2nd positive integer

(x+1) is the next positive integer after x (Ex. 3 aka 2+1 is next integer after 2).

Larger Integer: x+1  ==> being squared

Smaller Integer: x ==> being multipled by 9

9x + 19 = (x+1)^2  ==> the square of (x+1) is 19 more that 9 multiplied by x.

9x + 19 = (x+1)(x+1)  ==> simplify

9x + 19 = x(x+1) + 1(x+1)   ==> distribute (x+1) to x and 1.

9x + 19 = (x*x + 1*x) + (1*x + 1*1)  

9x + 19 = x^2 + x + x + 1  ==> simplify

9x + 19 = x^2 + 2x + 1

19 = x^2 - 7x + 1  ==> subtract 9x on both sides

Make one side of the equation equal to 0 so you can factor the equation:

0 = x^2 - 7x - 18  ==> subtract both sides by 19

0 = x^2 + 2x - 9x - 18  ==> 2x - 9x = -7x and 2 * (-9) = -18

0 = x*x + 2x - 9x - 18  

0 = x(x + 2) - 9(x + 2)  ==> factor

0 = (x - 9)(x + 2)

x - 9 = 0         x + 2 = 0

x = 9                     x = -2

Out of x = 9 and x = -2, only x = 9 is positive.

Hence, x = 9 and x+1=10.

Hence, the answers are 9 and 10.

In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used

Inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa

If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.

From the question,

x>3 (x should be greater than 3) means the the value of x is more or greater than 3, that is, x is 4,5,6,...

a) The equation of line is y = 270x + 10640.

b) The annual cost value in 2013 for age 17 is $15,320.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Points (8, 12800) and (14, 14420)

So, the slope is

= (14420 - 12800)/(14-8)

= 1620/6

= 270

and, the slope intercept form

(y - 12800) = 270 (x - 8)

y- 12800 = 270 x  - 2160

y = 270x + 10640

b) Now, x= 17

y= 270(17) +10640
