For this case you have the following advantages:
1) you can see the graph of both equations
2) you can see where the equations intersect
3) the point of intersection represents the solution to the system of equations.
4) You can solve the problem in much less time than doing it by hand
5) You can find very accurate solutions.
No, the question is not a statistical question.
Answer:
37/100 is already simplified, as a decimal 37/100 is 0.37 and as a percentage 37/100 is 37%
What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
Answer:
7
Step-by-step explanation:
The angles that we are sure about is 33 and 90. The angles of a triangle add up to 180. 33 + 90 = 123. 180 - 123 = 57. 57 = 7x+8, 49 = 7x, x = 7.
