Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
Answer:
0.01
Step-by-step explanation:
you just have to do the opposite. Since the is n*-5/8 you want to use inverse operation and do -0.4 divided by -5/8 when you do that you end up with 0.01. So the value of n is 0.01
34255 = 5 * 13 * 17 * 31
203515 = 5 * 13 * 31 * 101
So GCD(34255, 203515) = 5 * 13 * 31 = 2015
Answer:
1. You first have to find the slope
2. Next, you have to find the y-intercept
3. Finally, you have to put it in y = mx + b form.
Step-by-step explanation:
The slope of 2 points is; 
The y-intercept is; 
y = mx + b
m is always the slope
b is always the starting point or y-intercept
Answer:
y = 7x - 4
just as it says in words
