<span>Each set of prices can be described by a linear function. In this case, Company A would be y = 5 + .5x, where y is the fare and x is the number of miles driven. Similarly, Company B would b y = 10 + .1x. The definition of intersection tells us that two lines interstect only at that point where their x and y coordinates are identical, which means, of course, that their y coordinates will be identical. So to find the point of intersection we can examine the point where the y coordinates are the same. Which is to say, where 5 + .5x = 10 + .1x. We can simplify this to .5x - .1x = 10 - 5, then .4x = 5, and finally, x = (5/.4) = 12.5. In other words, the fares will be equal when the miles driven is 12.5</span>
Solution in attachment.
<h3>x = -6, y = 9, z = -3</h3>
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.
First, make a equation in which r= red and b=blue.
So, since in the first box it has 4 red models and one blue model equaling 12,
the first equation looks like 4r+b=12.
The second equation looks like 2r+b=8.
What you would do is try and first solve for r by getting rid of b.
Since both equation has a positive b, you would make one equation have a negative b by multiplying the whole equation by -1.
-1*(2r+b=8)= -2r-b=-8
Add.
4r+b=12
+(-2r-b=-8)
2r=4
r=2
Then, you plug in 2 for the r for any of the original equations.
4(2)+b=12
8+b=12
b=4
or
2(2)+b=8
4+b=8
b=4
So, the red models weigh 2 pounds while the blue models weigh 4.
