now, we're assuming they're directly proportional, so say y = miles, x = hours.
B - Parallelogram
To find this, graph it on a paper or make a mental image in your mind. With this, it would form an image of a parallelogram.
Hope this helps!
<span>3x^2 = 7x - 3
Rearranging,
</span><span>3x^2 - 7x + 3 = 0
</span>Using quadratic formula :
x= [7 + sqrt (49 - 36)]/6
x= [7 + sqrt 13]
or
x= [7 - sqrt (49 - 36)]/6
x= [7 - sqrt 13]/6
<span>d. x - 7 plus or minus the square root of 13 divided by 6</span>
