Answer:
B
Step-by-step explanation:
The equation of proportionality is
y = kx ← k is the constant of proportionality
Here k = 2 , then
y = 2x
This means that the y- coordinate is twice the x- coordinate
The only point where this is true is the point
(2, 4 ) → B
Answer:
Step-by-step explanation:
Given sequence:
Therefore,
General form of an arithmetic sequence:
(where a is the first term and d is the common difference)
To find the common difference, subtract a term from the next term:
Therefore,
To find the 6th term, input n = 6 into the equation:
Answer: y=-14.5 hope it helps :)
Answer:
7
Step-by-step explanation:
It is 7:
31 - 7 = 24
15 - 7 = 8
8/24 = 1/3 = 33%
It is not 12:
31 - 12 = 19
15 - 12 = 3
3/19 = 15%
It is not 6:
31 - 6 = 25
15 - 6 = 9
9/25 = 36%
It is not 9:
31 - 9 = 22
15 - 9 = 7
7/22 = 31%
It is not 11:
31 - 11 = 20
15 - 11 = 4
4/20 = 20%
<u>I subtracted the option from 31 (the new total of marbles) and from 15 (the new total of blue marbles). Then, I divided the new total by the new total of the blue marbles. I converted the decimal into a percentage. If the percentage was not 33%, then it was not the answer.</u>
Let's assume
depth of pound over time is h cm
time in hours as t
We are given
At the beginning of a storm, a pond was 16 cm deep
so, we get
so,
we can use formula
the depth increased by 1.5 cm every hour for 8 h
so, we get
so, we can plug these values
and we get
now, we can draw graph
Graph:
