Use the points (2, 2485.6) and (6, 1172.5) to write an equation of the line of fit in slope-intercept form. Let x be the years since 2010 and let y be the number of CDs in millions sold.

Answers

Answer:

y = -328.275x + 1829.05

Step-by-step explanation:

In this case, we need to write an equation of this form:

y = ax + b  (1)      a: slope    b: intercept

In order to calculate the slope, we need to use the following expression:

a = y₂ - y₁ / x₂ - x₁     (2)

So, we have two points here, so, from these points we can identify each of the elements so we can determine the slope.

Point 1: (2, 2485.6)

Point 2: (6, 1172.5)

The slope of this equation will be:

a = 1172.5 - 2485.6 / 6 - 2

a = -328.275

Now that we have the slope, to get the intercept "b", we just use any of the given points, and replace in the general equation (1) to solve for b:

2485.6 = -328.275(2) + b

b = 2485.6 - 656.55

b = 1829.05

With the value of a and b, we can write the general equation of the line for this:

y = -328.275x + 1829.05

the perimeter of a rectangular court is 224 feet. The length is 4 feet more than the width. Write and solve an equation to find the dimension of the court.​

Answers

Perimeter = 2l + 2w
L=4+x
W= x

224 = 2(4+x) + 2x
224 = 8+2x+2x
216 = 4x
54 = x

Plugging x = 54 into initial dimensions:
L = 54 + 4 = 58
W = 54

Answer:

C. 350 pounds

Step-by-step explanation:

Looking at the chart, week 22 would be between the week 20 and week 25 marks. As a result, the weight should be between 275 and 425 pounds. As a result, A is out. Week 22 will be bigger than week 20 (275), so B is also out. Week 22 is in between Week 20 and 25, so it isn't bigger than Week 25's pumpkin; D is out for this reason. That leaves C, 350 pounds, as our answer.

In your own words, what is a radical expression?

Answers

Answer:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.

The term underneath the radical symbol is called the radicand.

Suppose you know x+2y=-1 and 3y-x=-19. What is xy?
