The first thing we must do in this case is to define the variables.
We have then:
v: the value of the bicycle
t: years
The standard equation of the line is:
v-vo = m (t-to)
The slope is:
m = (v2-v1) / (t2-t1)
Substituting values:
m = (640-850) / (3-0)
m = -70
We choose an ordered pair:
(to, vo) = (0, 850)
Substituting values:
v-850 = -70 (t-0)
Rewriting:
v = -70t + 850
Answer:
assuming it decreases in value by the same amount each year, a linear equation for the value of the bicycle, v, when it is t years old is:
v = -70t + 850
F(-4)= 9*3^(-4)=9/(3^4)=1/9
Do you mean Y=|-3x- 2|-4 or Y=|-3x+2|-4
Answer: There are 35 spellers participated in the spelling bee.
Step-by-step explanation:
Since we have given that
Rank of Anish's placement at the highest = 11 th
Rank of Anish's placement at the lowest = 25 th
We need to find the number of spellers participated in the spelling bee.
So, Number of spellers participated in the spelling bee is given by
Highest + Lowest - 1
= 11 + 25 - 1
= 36 - 1
= 35
Hence, there are 35 spellers participated in the spelling bee.
