Answer:

f(x) = {    29 ,                                0≤x≤250

          0.35 (x-250) + 29             250< x< ∞ }

Step-by-step explanation:

Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29. For any minute of 250, Tracy is charged $0.35 per minute

For first 250 minutes the flat charge is 29

LEts x be the number of minutes called

x- 250 be the minutes  to be charged

Tracy is charged $0.35 per minute

so charge = 0.35(x-250) + 29

We write piece wise function for 0 to 250 minutes and then for above 250 minutes

f(x) = {    29 ,                                0≤x≤250

          0.35 (x-250) + 29             250< x< ∞ }

The speed, v, of a wave is inversely proportional to the square root of the
yKpoI14uk [10]

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

v \sqrt{d} = k    

If v  = 30 and d = 400, then

30(\sqrt{400}) = k

k = 30(20) = 600

Now v \sqrt{d} = 600

If d = 25, then v\sqrt{25} = 600

                         5v = 600

                            v = 120

2.5x + 1.5 = 4x - 11 what is x
Alexeev081 [22]

Answer:

X = 8.3 (shortened)

<u>Steps for answer!</u>

1. Subtract 2.5x from both sides.

1.5=4x-11-2.5x

2. Simplify  4x-11-2.5 to  1.5x-11

1.5=1.5x-11

3. Add 11 to both sides.

1.5+11=1.5x

4. Simplify  1.5+11 to 12.5.

12.5=1.5x

5. Divide both sides by 1.5.

12.5/1.5=x

6. Simplify  12.5/1.5 to  8.3333338.333333.

8.333333=x

7. Switch sides.

x=8.333333
