Answer:
x=-5, y=-2. (-5, -2).
Step-by-step explanation:
x-3y=1
-x+6y=-7
----------------
3y=-6
y=-6/3
y=-2
x-3(-2)=1
x+6=1
x=1-6
x=-5
The advantage of the graphing calculator is that you just have to find two independent equations, introduce them in the calculator and it will find the intersection point ot the two graphs.
The equations that you have to introduce are:
1) y = 2.25x + 24
2) y = 2.75x + 23
The algebraic solution, which will give you the same coordinates of the intersection point of the graphs is
2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1 => x 1 /0.5 = 2.
Answer: 2
Answer:
2, 5, 10
Step-by-step explanation:
50 divided by 2 = 25
50 divided by 5 = 10
50 divided by 10 = 5
50 divided by 15 = NOT POSSIBLE
