What is the slope between the points (3,-4)& (7,6)? a.) -2/3 b.) 10/3 c.) 2/3 d.) -10/3

The slope is

Step-by-step explanation:

1. You need to apply the following formula for calculate the slope:

2. Given the points, (3,-4) and (7,6), you have:

3. Substitute these values into the formula for calculate the slope, as following:

4. Simplify the result. Therefore, you obtain that the slope is:

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
