Solve for x. Write both solutions, separated by a comma.7x^2-4x-3=0

x = -3/7   x=1

Step-by-step explanation:

7x^2-4x-3=0

Factor

(7x+3)(x-1)=0

Using the zero product property

7x+3 =0  x-1 =0

7x = -3   x=1

x = -3/7   x=1

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
