Answer: 2/1x
Step-by-step explanation:
you follow the graph from the y intercept to the next point
up 2 over 1
Answer:
7x−3=7k,x=7k+3,k∈ℤ
Step-by-step explanation:
3x ≡ 2 (mod 7)
3 is a solution, since 3×3−2=7.
All solutions are 3+7ℤ
y=3x−2/7=3(x−3)+7/7=3(x−3)/7+1
7x−3=7k,x=7k+3,k∈ℤ
Answer:
53
Step-by-step explanation:
50 - 12 = 38
38 + 15 = 53
Answer:
24 Years
Step-by-step explanation:
Rule of 72 is an approximation that you can use to estimate the time it will take for something to double in value at a compound rate of interest
use the following equation
72/(i*100)
we have
72/(.03*100)
72/3=24
