Answer:
Step-by-step explanation:
Let
x ----> the number
we know that
The phrase " the phrase: the difference of a number and 9" is equal to
subtract the number 9 from the number x
(x-9)
The phrase" no more than 95" means "less than or equal to 95" (≤95)
so
The inequality that represent this situation is
The answer for this is m
=
5.436564
v

Pare a.) $70 is what he would have left. Since each trip is $14 you would multiply that by the amount of times he went which was 11. 14x11 is $154. But you need what he has left so you take his total amount $224-$154 and get $70.
Part b.) 16 times. He has $224 total. You want to find out how many times he can go on the tool roads. We know the toll roads cost $14 each time. So you do $224/14 and get an even amount of 16. He would be able to use it 16 times before he have no money left.
You follow the rules for the quadratic formula, where
x= (-b +- √(b²-4ac) )/2a
Filling a, b and c in yields
x = (8 +- √(64-164) ) / 2 =>
x = (8 - √-100)/2 or x = (4 + √-100)/2
Well, √-100 = 10i, so then you simplify to the last answer, D:
x = 4-5i or x=4+5i
