If you would like to know what is true about the solution of the set of equations, you can calculate this using the following steps:
2x + 2y = 18
x + y = 9 /*2
______________
<span>2x + 2y = 18
</span>2x + 2y = 18
______________
2x + 2y = <span>2x + 2y
</span>18 = 18
0 = 0
The correct result
would be infinitely many solutions.
Answer:
Histograms have many benefits, but there are two weaknesses. A histogram can present data that is misleading. For example, using too many blocks can make analysis difficult, while too few can leave out important data.
1) 1ml % 6 marbles = about 0.17ml so the volume per marble is 0.17ml 2) 10-(0.17x4) = 9.32 so that is the original volume 3) then 9.32 + (0.17 x 13) = 11.53ml 4) it is linear because for every marble placed inside the cylinder the volume increases by about 0.17ml the slope means amount of marbles placed vs. volume in cylinder
