The graph of the equation y=1/2x−3
determine the value of y for the point (4, y).

All you need to do for this problem is substitute in 4 for your x value and solve. So it would be y=1/2(4)-3. Basic PEMDAS indicates that you would multiply out 1/2*4 (2) and then subtract 3 (-1).

Y = 1/2(4)-3

Y = 2-3

Y = -1

Point (4,-1)

so, converting firstly the mixed fractions to improper fractions and then "adding".

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
