for
f(x)= 4x + 3
f(0) would be
f(0)= 4*0 + 3, or just 3
x is just set to 0 and everything it multiplies with vanishes
if x < 0 the result is smaller then 3
if x > 0 the result is bigger than 3
C and E, evaluate the numbers outside of the parenthesis to the inside
Answer:
neither
Step-by-step explanation:
The one is c okkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk
First, lets find how many miles the cyclist can ride per minute (speed = distance/time).
18/45 = 0.4 miles per minutes
Second, lets find how many miles the cyclist can ride per hour.
0.4 * 60 = 24 miles per hour
Third, lets find how many miles teh cyclist can ride in 6 hours.
24 * 6 = 144 miles in 6 hours
Best of Luck!
