Answer: $y=-0.54x+19.8$

Step-by-step explanation:

Because it is asking for a line, it cannot be the first option (which is a quadratic) or the fourth option (which is an exponential).

This leaves us with the second and third options.

Since the line will have a negative slope (as the data is decreasing), this means that the only viable option is $y=-0.54x+19.8$ .

Answer:

30 inches

Step-by-step explanation:

She takes 12 equal sized steps and they all add up to 10 yards.

The length of each step (in yards) is:

10 / 12 = 5/6 yards

The question requires the answer in inches, therefore, we must convert this to inches:

1 yard = 36 inches

5/6 yards = 5/6 * 36 = 30 inches

Each step is 30 inches long.

Step-by-step explanation:

The volume (V) of a pyramid is

V = $\frac{1}{3}$ area of base × height, hence

Simplify foundation of alegebra

Eva8 [605]

1.) -8 + 10(6 + 4r)

First multiply the 10 into (6 + 4r)

-8 + 60 + 40r

52 + 40r

2.) (8m² - 8m + 8) - (2m - 7m² - 6)

Distribute the - into (2m - 7m² - 6)

8m² - 8m + 8 - 2m + 7m² + 6

Combine like terms

15m² - 10m + 14

(idk if you need to factor this or if you can leave it as is)

Which expression results from dividing 6x^8-4x^6 by 2x^2

pogonyaev

$\frac{6 {x}^{8} - 4 {x}^{6} }{2 {x}^{2} } = \frac{2 {x}^{6}(3 {x}^{2} - 2) }{2 {x}^{2} } = 2 {x}^{4}(3 {x}^{2} - 2)$
