3n-21= -30
3n = -9
n= -3
Answer:
3b+b and 2(2b)
Step-by-step explanation:
The numerical form of this worded expression is:
10(1/2n + 6)=8
Each time x increases by 2 (eg: from x = -3 to x = -1), the value of y increases by 7 (eg: y = 9.5 to y = 16.5)
Change in y = 7
change in x = 2
Slope = (change in y)/(change in x) = 7/2 = 3.5
This all means that we have a linear equation
Answer:
C=0.55M+24.65
Step-by-step explanation:
