Carrie makes 3/4 servings using 4/7 cups of flour how many servings of cookies does Carrie make with one cup of flour

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer is the third / last answer

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
