y=-0.02x2+2.4x
This is a downward facing parabola.. It will have a maximum when dy/dx = 0
dy/dx = -0.04x+2.4
-0.04x+2.4=0
-0.04x=-2.4
x=60
y has a maximum of 72 when x=60
It is an equation and the value of a is 7
To find the value of "what" in the equation "what - what equals 477," we can set it up as "x - x = 477." However, since any number minus itself equals zero, there is no value of "what" that satisfies this equation. Therefore, the equation is not solvable in standard arithmetic.
