Answer:
y=0.8x
Step-by-step explanation:
take two points from the graph
(5,4) and (0,0)
then do y2-y1/x2-x1
4-0/5-0
4/5=.8

Answer:
an = 5 + 2n
Step-by-step explanation:
Each time it increases by the same amount (2), so this is an arithmetic sequence:
an = a₁ + d (n - 1)
Given a₁ = 7 and d = 2:
an = 7 + 2 (n - 1)
an = 7 + 2n - 2
an = 5 + 2n
Check our answer:
n=1: a₁ = 5 + 2(1) = 7
n=2: a₂ = 5 + 2(2) = 9
n=3: a₃ = 5 + 2(3) = 11
n=4: a₄ = 5 + 2(4) = 13
Answer:
D
Step-by-step explanation:
200 is the weight of the jar
110 is the weight of the contents
n is the number of jars.
The equation is for mass of an "n" number of jars
