Answer:

8/5

Step-by-step explanation:

You can rewrite the equation to 2/5 * 12/3

Which is equal to 2/5*4

So 2 times 4 is 8

So the answer is 8/5

Hope this helps!

Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to H

MrRissso [65]

g(x) = x3 – x2 – 4x + 4

You can find the zeroes by factoring the equation. x2 (x - 1) - 4(x - 1) = 0

(x2 - 4) (x - 1) = 0

(x + 2) (x - 2) (x - 1) = 0

x = 2, -2, and 1

The following are the key features of g(x):

g'(x) yields the slope

g''(x) yields the concavity

g'(x) = 0 provides the critical points

g''(x) = 0 provides the point of inflection

Mrac [35]

Answer:

43.75 inches or 43 and 3/4 inches.

Step-by-step explanation:

Ok, thanks for the complement of information.

So, to find the volume of that step, which is a rectangular prism, we would use the simple formula:

V = length * width * height

In this case, we have the total volume (3,500 cu in), we have the width (10 inches) and we have the height (8 inches). But we need to find out the new length in order for him to use all 3,500 cu in of cement.

So, we transform the formula above into:

length = V / (width * height)

then we plug-in the numbers:

length = 3,500 / (8 x 10) = 3,500 / 80 = 43.75

So, the new length of the step would be 43.75 inches or 43 and 3/4 inches.

Answer:

D (7, 0.5)

Step-by-step explanation:

The equations must be interpreted to be ...

y = -1/2x +4
y = 1/2x -3

A graph shows the solution to be (7, 0.5), matching selection D.

___

You can add the two equations together to get ...

(y) +(y) = (-1/2x +4) + (1/2x -3)

2y = 1 . . . . . simplify

y = 1/2 . . . . .divide by 2

It can be convenient to use the second equation to find x.

1/2 = 1/2x - 3

1 = x - 6 . . . . . . multiply by 2

7 = x . . . . . . . . . add 6

The solution is (x, y) = (7, 0.5). . . . . matches selection D.
