Find the root of the equations: 1/6x-1/6-2/9x-1 1/9=-2

plzz explain

x=13

Step-by-step explanation:

we have

Convert mixed number to an improper fraction

substitute in the equation

Find out the LCM of 6 and 9

LCM=18

Multiply by 18 both sides to remove the fractions (multiplication property of equality)

Combine like terms left side

6 meters

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
