Answer:
No.
Step-by-step explanation:
If any x value (left to right) is repeated (as shown by having a line over it multiple times) the answer is not a function.
Slope: -4
Y-intercept : (0, -10)
Answer:
A(w) = -
+ 100w
Step-by-step explanation:
First, we need to find down the length (l) of the rectangular area in term of w
We have 200 feet of fencing is the perimeter of the rectangular area, which mean:
2 (w + l) = 200
<=> l = 100-w
But the area of land: w*l
= w (100-w)
=-
+ 100w
So, A(w) = -
+ 100w
The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
