The graphed line can be expressed by which equation?

Mathematics

Answer:

y+2 = 2/3(x+2)

Step-by-step explanation:

We have 2 points (-2,-2) and (4,2)

so we can find the slope

m= (y2-y1)/(x2-x1)

  = (2--2)/(4--2)

  = (2+2) / (4+2)

  = 4/6

   = 2/3

The slope is 2/3

We can use point slope form to find the equation of the line

y-y1 = m(x-x1)

y--2 = m(x--2)

y+2 = 2/3(x+2)

Answer:y+2 = 2/3(x+2)

Step-by-step explanation:

You can’t find this answer by taking the two points on the line and setting them up as x-x and y-y and finding the slope And then using the slope to find the equation of the line.

Which products result in a difference of squares? Check all that apply.
Amanda [17]

Answer:

2nd - (w - 5)(w + 5)

4th - (-4v - 9)(-4v + 9)

Step-by-step explanation:

1. The first option shows an expression multiplied by its opposite(x -1), so therefore, it does not show the difference of squares

2. The second option does show the difference of squares because it is in the form (a + b)(a - b)

3. The third option is just a square because the same expression is multiplied by itself.

4. The fourth option is the difference of squares because it is in the form (a + b)(a - b). a equals -4v and b equals 9 in this case.

5. The fifth option is not the difference of squares. No term in common in both expressions

6. The sixth option is just a square because the same expression is multiplied by itself.

In all, there are two options that are the difference of squares, the 2nd and 4th.

Answers

1) 4

2) 0, 2, -10

3) 0, 5, -2

Step-by-step explanation:

1) x³ - 64 = 0

x³ = 64

x = 4

2) x³(x² + 8x - 20) = 0

x³(x² + 10x - 2x - 20) = 0

x³(x(x + 10) - 2(x + 10)) = 0

x³(x + 10)(x - 2) = 0

x = 0, 2, -10

3) x³ - 3x² - 10x = 0

x(x² - 3x - 10) = 0

x(x² - 5x + 2x - 10) = 0

x(x(x - 5) + 2(x - 5)) = 0

x(x - 5)(x + 2) = 0

x = 0, 5, -2

GuDViN [60]

Answer:

B

Step-by-step explanation:

Since a function would mean that a customer is able to purchase 1.1 of an item or 1.5 of an item, which is false. It also means that the customers pay the same price for a different amount of items.
