Answer:

f(5) = 75

Step-by-step explanation:

The function is f(x) = 2x^2 + x(100 - 15x).

Evaluate this function at x = 5:  replace each instance of x with 5:

f(5) = 2(5)^2 + 5(100 - 15·5)

Order of operations rules require evaluating the expression enclosed in parentheses first.  We get:

f(5) = 2(5)^2 + 5(100 - 15·5)

      = 50       + (100 - 75), so that:

f(5) = 50 + 25 = 75

f(5) = 75

Answer:

y<-2x-3

Step-by-step explanation:

Your first step is to find the equation of the line. You can see that the y-intercept is -3, therefore your b is -3. So now your formula looks like this:

y=mx-3

To find m, you substitute in an x value and its corresponding y value. When you do this you will get -2.

Now it looks like this:

y=-2x-3.

Now that you have the equation of the line, you can look at the inequality. Since the line is dotted, that means it is not included in the inequality. That mean it cannot contain an equal to. So the only options we have are < and >. Since the shaded area is to the left, which is the negative side, we can conclude that y<-2x-3 is the correct equation.

HOPE THAT THIS IS HELPFUL!
