In the proportion
what does x equal?
a.12
b.14
c.16
d.17

C

Step-by-step explanation:

Anyone who can do latex as well as you can, will likely catch onto this very quickly. Anyway, let's see.

Cross Multiply

4(x + 2) = 9*8                 Remove the brackets on the left and multiply the right.

4x + 8 = 72                     Subtract 8

4x = 64                           Divide by 4

x = 64/4

x = 16

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step-by-step explanation:

the answer is 128
