Answer:
17%
Step-by-step explanation:
99.45-85=14.45
14.45/85= 0.17
0.17= 17%
B is in standard form
Step-by-step explanation: standard form is y=mx+b
Answer:
It is
5/7
Explanation:
The number
5/7
tells you that when
x
increases of
1
then
y
always increases of
5/7
.
Graphically:
graph{7/7*x [-10, 10, -5, 5]}
Step-by-step explanation:
First, multiply both sides by y to get rid of that y in the denominator.
Then, rearrange it to put it into standard form so you can easily see the values for a, b, and c.
Plug into quadratic formula, and you get this result:
So, y=4, y=8/3
If 3x>96, dividing both sides by 3 we get that x>32, therefore only E is an acceptable answer
