Answer:
x= 66
Step-by-step explanation:
if you set up the equation mathematically, it would be x+0.5x=99, because 50% is essentially just 0.5.
so, now that you have the equation, you have to add like terms, so it would be 1x+0.5x=99, and 1+0.5 is 1.5, so youre left with the equation 1.5x=99.
from there, you solve for x by dividing each side by 1.5:
1.5x=99
/1.5 /1.5
x=66
im sorry if this didnt make much sense, but i hope this helped!! :D

Answer:
f(6) = -5
f(x) = 0 and x=1 and x=5
Step-by-step explanation:
f(6) is the value when x=6
looking at the graph when x=6 f(6) = -5
f(x) = 0 means the y value is 0 This occurs when x = 1 and x=5
