Algebraically:
|y-x|=13
x^2+y^2=125
The numbers are -2 and 11.
In one month, there are on average 30 days.
So if he talks 135 minutes per month, he talks on average 135/30 minutes per day
135/30 = 4.5
So on average he talks to his grandfather for 4 minutes and 30 seconds a day.
On a graph, an exponential growth is shown as a line going up as you go from left to write. In an equation, exponential growth is shown if the b part of y=ab^x is greater than one.
Answer:
SA=120 m^2
Step-by-step explanation:
SA=(9x5)+(3x4)+(9x4)+(9x3)
SA=120
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
we have the points (2,14) and (4,28)
Find out the constant of proportionality k
For (2,14) ---->
For (4,28) ---->
so
the value of
therefore
The equation is
