Simple you just solve for y and put the equation in slope-intercept form
Answer:
Step-by-step explanation:
8b - 7 = 7b - 2
Bringing like terms on one side
8b - 7b = - 2 + 7
B = 5
-12 + 5k = 15 - 4k
Bringing like terms on one side
5k + 4k = 15 + 12
9k = 27
k = 27/9 = 3
Answer:
4a-4b
Step-by-step explanation:
In the numerator, we can simplify this: (2a-2b)^2 = ((2)(a-b))^2 = (2)^2(a-b)^2 = 4(a-b)^2 = 4 (a-b)(a-b). Thus, we get: (4(a-b)(a-b))/(a-b). We can cancel the top and bottom with a-b and get: 4(a-b) = 4a-4b.
I hope this helps!
Answer:
30:50
Step-by-step explanation:
80 Students.
