GRAPHING CONS
1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.
2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.
3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution
SUBSTITUTION CONS
1) Becomes tedious if a system has too many equations or variables
ELIMINATION PROS/CONS
1) basically same as substitution
Answer:
72
Step-by-step explanation:
36 x 2 = 72
To check your answer:
72 / 2 = 36
Answer:
Step-by-step explanation:
C
<span>5° below zero is -5 degrees
</span><span>The temperature of a solution in beaker two what is the opposite of the temperature in beaker one so it's 5 degrees above zero
</span>
answer
<span>5° above zero</span>
Setup the equation from the words as follows:
√
3x/5
=x
Simplify this to:
0=x(5x−3)
Since we are toldx≠0,x=3/5.
