Ineed with finding four solutions of 5x + 3y = -3, and i have to write them in ordered pairs. for the x values i chose, -1, 0, 1, 2. but i was only able to figure out 0. me find the y values and putting it as ordered pairs. the answers have to be written like this (-1,y), (0,-1), (1,y), and (2,y). you

answer: about 22.67

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
