Answer:
12
Step-by-step explanation:
When F = 18; d = 2
Cross multiply;
18 x 4 = K
72 = K
There the equation connecting F and 
is
Now, Find F when d = 6
All you do is to substitute d = 6 in to
Therefore;
F = 12
Please mark me brainiest if correct.

Step-by-step explanation:
honestly im not really
Because I see a graph in the picture, I am assuming you need to graph the equations. The two equations are in slope-intercept form. They are in the form
y = mx + b
Where m is the slope and b is the y-intercept. That is why it is called the slope-intercept form.
If you want to graph a slope-intercept form equation, first plug in a value for x then compute it to get the y-coordinate.
First, let's get some points with the equation y = 4x + 3
We will plug in three values for x. 0, 1, and 2.
When x = 0
y = 4(0) + 3
y = 3
When x = 1
y = 4(1) + 3
y = 7
When x = 2
y = 4(2) + 3
y = 11
Now we have the points (0, 3), (1, 7), and (2, 11)
These points are called ordered pairs. Where the first number is the x-coordinate and the second number is the y-coordinate.
The ordered pairs tell you how many times you move your point away from the origin. The origin is (0, 0).
The first number of an ordered pair tells you how many times to move in the x direction and the second number how many times in the y direction.
Now graph the second equation. y = -x - 2
Just plug in some values for x.
I picked 0, 1, and 2.
When x = 0
y = 0 - 2
y = -2
When x = 1
y = -1 - 2
y = -3
When x = 2
y = -2 - 2
y = -4
Now we have the points (0, -2), (1, -3), and (2, -4)
Now plot those points and draw a line through them.
If you need to find the intersection of the equations y = 4x + 3 and y = -x - 2 you need to find where they intersect. Or in other words, share a common point.
After playing around with the numbers, I got the intersection point for the both of the equations.
It is the ordered pair (-1, -1). This the solution to both of the equations. If you plug in the ordered pairs into both of the equations, they will show it belongs to their graphs.
Plug in the values for y = 4x + 3
-1 = 4(-1) + 3
-1 = -4 + 3
-1 = -1
Plug in the values for y = -x - 2
-1 = -(-1) - 2
-1 = 1 - 2
-1 = -1
So, this ordered pair is on both equations!
Answer: <em>u = 6</em>
Step-by-step explanation: To solve for <em>u</em> in the equation you see here, we must first isolate the term containing <em>u</em> which in this problem is -6u.
Since 7 is being added to -6u, we subtract 7 from both sides of the equation to isolate the -6u. On the left side of the equation, the +7 and -7 cancel out and on the right side of the equation, -29 - 7 is -36 so we have -6u = -36.
Now we can finish things off by just dividing both sides of the equation by -6. On the left the -6's cancel and on the right -36 divided by -6 is 6.
So u = 6 and you can check your answer by 6 back in for <em>u</em> in the original equation shown below in italics.
<em>-6 (6) + 7 = -29</em>
