Answer:
Step-by-step explanation:
Given
Garden:
One Bag:
Requires
Determine the number of bags to cover the whole garden
This is calculated as thus;
Expand the numerator
Express 81 as 9²
Evaluate as difference of two squares
Hence, the number of bags is
For Ax+By=C, we have y=-3x. We want both the y and x variable on the same side, and that leads us to either subtract y from both sides or add 3x to both sides. You can do either, but I personally prefer the latter, so we have 3x+y=0. We have A=3 (since that is the coefficient for x) and B=1 (since 1*y=y). Lastly, C=0

Answer:
Option 3:
Graph C
Step-by-step explanation:
Find the solution of
(multiplication property of equality)
Divide both sides by -1. Since we are dividing by a negative number, the sign would change
This means that the possible values of x are 8 and any number above 8.
Graphing this, the arrow of directed line would start at 8 and move towards our right hand.
Thus, the graph would be graph C in option C.
