What is the answer and work shown for 9r+r+7b+10+b+r+4n

11 r + 4 n + 8 b + 10

Step-by-step explanation:

Simplify the following:

9 r + r + 7 b + 10 + b + r + 4 n

Grouping like terms, 9 r + r + 7 b + 10 + b + r + 4 n = (9 r + r + r) + 4 n + (7 b + b) + 10:

(9 r + r + r) + 4 n + (7 b + b) + 10

9 r + r + r = 11 r:

11 r + 4 n + (7 b + b) + 10

7 b + b = 8 b:

11 r + 4 n + 8 b + 10

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
