y intercept = 1/2
<u>Step-by-step explanation:</u>
Step 1:
Formula y=mx+b in Slope Intercept form( whereas m= slope of the given equation, b= y intercept)
Step 2:
Comparing the given equation y = -3x + 1/2
we get m=-3(Slope) and y-intercept b=1/2
If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.
If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x
Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.
The two numbers are 4 and 16.
They aren't similar because they're not proportional (the sides do not form equal ratios)<span />
The largest number that 8c could be is -15
