If y = 6, what is the value of x given 8x + 5y = 62?

Marquise has 200 meters of fencing to build a rectangular garden. the garden's area (in square meters) as a function of the garden's width w w (in meters) is modeled by: a ( w ) = − w 2 + 1 0 0 w a(w)=−w 2 +100w what side width will produce the maximum garden area? meters

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x

Hi i’m not sure how to do question 20 if u could explain how to do it that’d b great
