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.
An absolute value equation that equals 13 can be expressed as |x| = 13. This equation indicates that the value of x can be either 13 or -13, since the absolute value function measures the distance of a number from zero, regardless of its sign.
