Answer:

He own 9 gray t-shirts

Step-by-step explanation:

Red: 28 * 1/4

Blue: 28 * 3/7

Gray: x

28(1/4) + 28(3/7) + x = 28

    7     +     12     + x = 28

                             x = 28 - 7 - 12

                             x = 9

 Write a function with a zero of 1/2 . Explain how you know.
nalin [4]

Answer:

Simplest function is f(x) = 2x - 1

Step-by-step explanation:

When a function has a zero, simply put, that point is where the graph goes through the x-axis.  At this point, the y value is 0.

If a function has a 0 of 1/2, that translates to x = 1/2 and also (1/2, 0).  That means that y = 0 when x = 1/2.

If x = 1/2 and is a zero, then x - 1/2 = 0 and 2x - 1 = 0 (notice that y = 0 here and solving for x would get you right back to x = 1/2).

The simplest function with a zero of 1/2 is

f(x) = 2x - 1

You know it is true that the zero is 1/2 for two reasons.  First one is to set the right side equal to 0 and solve for x.

The second one is to graph the line y = 2x - 1 and see that it goes through the x axis at 1/2 where y = 0.
