The values of a, b and c for the equation 8x² - 2x = 1 are:

8, -2, and 1 respectively.
8, 2, and 1 respectively.
8, -2, and -1 respectively.

8, -2, and -1 respectively

Step-by-step explanation:

ax² - bx - c = 0

8x² - 2x = 1

8x² - 2x - 1 = 0

a = 8

b = -2

c = -1

8, -2, -1 respectively

i used to know how to do this in 7th but i forget easily

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
