Pretty sure that it is the first answer, the one with the back point between 6 & 8
Answer:
The answer is
<h2>12</h2>
Step-by-step explanation:
The above variation is written as

where k is the constant of variation
when y = 16
x = 3
k = yx²
k = 16(3)²
k = 16 × 9
k = 144
The formula for the variation is

when y = 1
We have

Cross multiply
x² = 144
Find the square root of both sides
x = √144
x = 12
Hope this helps you
Answer:

Step-by-step explanation:
by substitution what is before x² is considered as a
what is before x is b and the number alone(without x) with it's sign included is c
7x2=14
So the answer would be 2
