Answer:
to make a brige in a eassy to need to link the Ideas from the controling Idea to the hook
Step-by-step explanation:
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps

Answer:
8/3 km
Step-by-step explanation:
we can represent the given information on a table:
Kilometers time (hours)
2/5 ⇔ 1 1/2
and since we want to know how many kilometers (x) will be paved on 10 hours:
Kilometers time (hours)
2/5 ⇔ 1 1/2
x ⇔ 10
The relationship these 3 numbers have can be described by using the <u>rule of three,</u> which is to multiply the cross quantities on the table (2/5 by 10) and then divide by the remaining amount (1 1/2):
x =
÷ 
x =
÷ 
we use
x =
÷ 
and we make the division:
x =
÷
= 
we simplify the fraction by dividing the numerator and denominator both by 5, and we get the result:
x = 
thus, in 10 hours the crew will pave 8/3 km. Which is about 2.66 km.
