Answer:
f(x) = 3x - 5
g(x) = 6x^2 + 2x
Find: g(f(x))
method: for each x in g, substitute (3x-5)
g[f(x)]=6(3x-5)^2+2(3x-5)
=6(9x^2-30x+25)+6x-10
=54x^2-180x+150+6x-10
Step-by-step explanation:
First, you can add up 4+2 to get 6 because they’re both rates.
Next, divide 18 by 6 and you get 3.
So, it will take three hours for the boys to meet up.
One way to check your answer is to multiply 4x3=12 and 2x3=6 and 12+6 is 18.
I= PRT
680-500 = 500 x 0.12 x T (Interest= Future value - Pricipal)
180 = 60T
T=180/60
T=3 years

<u>Answer-</u>
has a slope of
<u>Solution-</u>
The general point slope formula of straight line,
Where,
m = slope
c = y-intercept
Comparing with general equation, slope =
Comparing with general equation, slope =
Comparing with general equation, slope =
Comparing with general equation, slope = 1, y-intercept =
Therefore, has a slope of
