Answer:
y=1/4x + 1.75
Step-by-step explanation:
1-2/2--2 = 1/4
2=1/4+b
b=1.75
A=10*8+((8-6)(15-10))/2
A=10*8+(2*5)/2
A=10*8+10/2
A=10*8+5
A=80+5
A=85 feet
Therefore the answer is D
Hope this helps :)
Simple....

x<6
This means that on your graph at 6 it's a circle (not colored in) and it goes to the left indefinitely...
Thus, your answer.
Well, you have to be given an interval. That is not an interval.
You should be given something like

If you add those fractions up you'll just get a point on the number line.
Find the LCD for all of them which is 9/6 - 4/6 + 3/6 = 8/6 = 2/3
You'll end up with a point on 2/3
