1) which ordered pair is a solution of the linear question shown in the graph above?
A) (-2, 0)
B) (1, 3)
C) (1-, 1)
D) (0, -1)

C) (-1, 1)

Step-by-step explanation: Format of a point (x, y)

First, you need to find the location of the x - axis.

Next, you need to find the y -axis point on the graph.

Lastly, you have to find where the two points meet (just follow the two line until they intercept)

and you're done! :)

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

a
