Answer: x^2+4
Step-by-step explanation:
Answer:
The solution of this system of equations is (3 , -8)
Step-by-step explanation:
The given system is
x + 2y = -13
12x + 5y = -4
We make x the subject of the first equation and put it into the second:

We put this expression for x into the second equation
12(-13-2y)+5y=-4
-156-24y+5y=-4
-24y+5y=-4+156
-19y=152
y=-8
We substitute y=-8 into x=-13-2y to get:

The solution of this system of equations is (3 , -8)
Just plot the points on the graph.
2. You know since the graph is a straight line, the ratios are proportional and therefore equivalent
Answer:
Length of each shelf is 0.45 meters
Step-by-step explanation:
Given


Required
Determine the length of each shelf
This is calculated by dividing the total length by number of shelves as thus:



Hence;
<em>Length of each shelf is 0.45 meters</em>
