The problem does not specify whether it is a proportional variation or an inversely proportional variation, so both cases will be solved.
<u>case a) proportional variation</u>
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
<u>Find the value of k</u>
<u>Find the value of y for x=
</u>
<u>the answer case a) is</u>
<u>case b) inverse variation</u>

Answer:
7/5
Step-by-step explanation:
4 + 3 = 7
-3 + 8 = 5
7/5
24~ 20, 15~20, 47~50, 42~40, 81~80, 65~70. Hope this helps
The first slope going up is when the function increases. when the line goes in a straight line it’s constant. abs when the slope goes down it’s decreasing. so in the photo it first increases, stays constant, decreases, stays constant, decreases
Answer: 17
Step-by-step explanation:
Use the Pythagorean theorem.
C^2 = A^2 + B^2
So, C is always the hypotenuse which is the longest side length and the side length diagonal of the right angle. Side "s" is the hypotenuse.
Square sides AB and BD
It looks like this:
C^2 = 8^2 + 15^2
8^2 = 64
15^2 = 225
225 + 64 = 289
the square root of 289 is 17
17 = s
