Answer:
2x + y = 4
Step-by-step explanation:
2x + y = 9 => y = -2x + 9
Parallel lines have the same slope so m = -2
Given (-1,6)
y = mx + b
6 = -2(-1) + b
6 = 2 + b
b = 4
so y = -2x + 4 or 2x + y = 4
Answer:
Option A i.e. y = - 3 is not in range of the piece wise function graphed.
Step-by-step explanation:
The range of a function y = f(x) is given by the possible values of y for the possible domain (x-values) of the function.
Now, it is clear from the graph of the function that the value of y never goes below y = - 2.
The graph is drawn in such a way that any value of y less than - 2 and greater than - ∞ is not in the range of the function.
Therefore, option A i.e. y = - 3 is not in range of the piecewise function graphed. (Answer)
Answer:
L=135 W=105
Step-by-step explanation:
Your rectangle has two length sides and two width sides. That means two sides are 30 feet longer than the other sides. If you subtract 60 from 480, you get 420. Divide 420 by 4 and you get 105. So now you know the width sides are 105 feet long, so 105+105=210. Now all you have to do is add 30 to 105 and get 135. That is the length of the two longer sides. So add 135 and 135 to get 270. All you have to do is add 210 and 270 and you end up with the 480 feet of fence you were given. I know this is probably not the fancy way of doing it, but it works.
