ANSWER

The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.

EXPLANATION

The given functions are:

f(x)=5x-1

g(x)=4x-8

To solve the equation 5x−1=4x−8 graphically, we need to graph f(x)=5x-1 and g(x)=4x-8 on the same graph sheet.

The x-coordinates of the point of intersection of the graphs of the two functions is the solution to the equation:

5x−1=4x−8

The third choice is correct.

Answer:

The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.

Step-by-step explanation:

These two lines do intersect and do not have the same y intercept so it cannot be the first two options

And since the problem is in term of x only, the third option is true

A spherical tank has a radius of 27 inches. find the volume of the tank in

murzikaleks [220]

Vol. of a sphere is V = (4/3)*pi*r^3, so in this case,

4*pi*19683
V = (4/3)*pi*(27 inches)^3 = ------------------ cubic inches
3

... which can be reduced to 26244 pi cubic inches, or 15.2 cubic feet

If you are examining a function over an interval ( a , b ) , for a and b finite, is it possible not to have an absolute maximum

uysha [10]

Yes, it is not possible to have an absolute maximum or absolute minimum.

Here,

We are examining a function over an interval ( a , b ) , for a and b finite,

We have to find, is it possible not to have an absolute maximum or absolute minimum.

What theorem indicates the existence of absolute maxima or absolute minima of a function?

If f is continuous on a closed interval [a, b] (that is: on a closed and bounded interval), then, the Extreme Value Theorem indicates the existence of an absolute maximum or minimum value of f on the interval [a, b].

Now,

The function is define over an interval (a, b).

Hence, the function is define on open interval.

So, it is not possible to have an absolute maximum or absolute minimum.
