Answer: x=-9/2
Alternative Form: x= -4 1/2, x= -4.5
SOLUTION
If the table represents an inverse variation, it means that y is inversely proportional to x, written as

Removing the proportionality sign and introducing a constant k, we have

In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have

So, if it's an inverse variation, the relationship would be

In the second column, x = -2 and y = 7.
Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation
We have

Since we got y = 7, the relationship is therefore an inverse variation.
The constant k = -14
The equation for the inverse variation is
Answer:
5.4 units
Step-by-step explanation:
From the figure ,it's clear that sin(50) = PQ/7
Then
PQ = 7×sin(50) = 5.362311101833
Therefore the approximate length of PQ I saw 5.4
Answer: Yes it is a function.
Step-by-step explanation: When trying to find out, you put it into a calculator and can tell by the line if it is a function.
