Answer:

t=r/d; t=0.2

Step-by-step explanation:

If d=r/t, then multiple both sides by t, to get td=r, then divide both sides by d, to get t=r/d. So t=8/40 t=0.2

If f(x) = 4x + 21 and g(x) = 2x + 2 what is f[g(7)]
Nana76 [90]

Answer:

we conclude:

 f(g(7)) =85

Step-by-step explanation:

Given

f(x) = 4x + 21

g(x) = 2x + 2

To determine

f(g(7)) =?

In order to determine f(g(7)), the first step we need to do is to determine g(7)

so substitute x = 7 in g(x) = 2x + 2

g(x) = 2x + 2

g(7) = 2(7) + 2

g(7) = 14 + 2

g(7) = 16

so now we have

f(g(7)) =f(16)

The next step to do is to substitute x = 16 in f(x) = 4x + 21

f(x) = 4x + 21

f(16) = 4(16) + 21

f(16) = 64 + 21

f(16) = 85

so we have

f(g(7)) =f(16)=85

Therefore, we conclude:

 f(g(7)) =85
