Let f(x) = 5x + 2 and g(x) = x2 – 1.
Find f(g(3))

Step-by-step explanation:

f(x) = 5x + 2

g(x) = x2 – 1

Think of it like a sandwich:

first solve what g(x) will be equal to when x = 3 (this is what's given in "f(g(3))" )and then plug in the answer into the equation of f(x) to find the final answer

the resulting equation will look like this:

f(g(3)) = 5[(3)2 - 1] + 2

just solve using PEMDAS

= 5[6-1] +2

=5[5] +2

=10+2

=12

f(g(3)) = 12

Hope this helps! :)

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

lol.

it's ok we all do this sometimes.
