Answer:

F(x) = 1/x^2

Step-by-step explanation:

F(x) = 1/x^2 is

y = 1/x^2

graph goes up to 10 each side

plug in 1,2,3,4,5,6,7,8,9,10 for x and see what y looks like

when x is 1,2,3,4,5,6,7,8,9,10

y is 1,1/4,1/9,etc

|x+5|+20=4 Needs to show work on how you came up with the answer.

arlik [135]

Answer:

No solution

Step-by-step explanation:

So we have the equation:

$|x+5|+20=4$

First, subtract 20 from both sides:

$|x+5|=-16$

Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.

Since this equals -16, this means that there is no solution.

And we're done!

Write the equations for 74,2 and 49

serious [3.7K]

Answer:

$x+10y=94$

Step-by-step explanation:

Assuming we want to find the equation (74,2) and (4,9)

This is an equation of a straight.

Let this equation be y=mx+b.

$m=\frac{9-2}{4-74} =-\frac{1}{10}$

We substitute the slope and (4,9) to get:

$y-9=-\frac{1}{10}(x-4)$

We rewrite in standard form to get:

$x+10y=94$

Find the values of x and y that maximize the objective function P=3x+2y for the graph. What is the maximum value?

AURORKA [14]

Answer:

(9, 0)

Step-by-step explanation:

Maximum or minimum value occurs at the Corner. The points given are (0, 8), (5, 4) and (9, 0).

Substitute (0, 8) in the objective function.

We get P = 3(0) + 2(8) = 16

Now for (x , y) = (5, 4)

P = 3(5) + 2(4) = 15 + 8 = 23

At (9, 0) we get P = 3(9) + 2(0) = 27.

Clearly, we have the maximum value at (9, 0).

And the maximum value is 27.
