Answer:
The value of the constant is 3
Step-by-step explanation:
Let
y ----> the height
x ----> the width
we have

This is the equation of a linear direct variation
The equation of the line passes through the origin
we have the points
(0.5,1.5), (2,6) and (3,9)
see the attached figure to better understand the problem
Find the value of the constant of proportionality k
For (0.5,1.5) ---->
For (2,6) ---->
For (3,9) ---->
therefore
The value of k is equal to 3
The linear equation is

or

Temperature at nightfall = -5 + 78 - 32 = 41 degree Farenheit
Answer:
9 + 7x
Step-by-step explanation:
14 + 3х - 5 + 4х
Subtract the numbers, and add the x's together.
9 + 7x
This is the furthest the expression can be simplified.
Hope this helps :)
Pie is an irrational number because it is 3.14. It is not a even number.
