1) 425000

2) 62.570000

Step-by-step explanation:

There are 5 under the 10.

1) 10 x 10 x 10 x 10 x 10 = 100000

100000 x 4.25 = 45000

2) There are 7 under the 10.

10 x 10 x 10 x 10 x 10 x 10 x 10 = 10000000

10000000 x 6.257 = 62.570000.

If you don't understand, count the "0's" and times then by 1 and 0's.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

maybe showing the graph would
