Answer:
100% Sure its b
Step-by-step explanation:
Replace the range for f(x)
So...
0=4-2x
x=2
4=4-2x
x=0
8=4-2x
x=-2
Solve!

Answer:
x=13 feet
Step-by-step explanation:
A ramp is between 1.96 and 1.80 feet, we will take 1.96
and R(x)=1.96 feet: we apply quadratic formula;
, where a=-0.05, b=0.8 and c=-1.96, so
solving
; we take the highest value of x, x=13
Answer:
Yes
Step-by-step explanation:
The smaller the negative number, the greater it is. i.e., -230 < -9.
