Answer:
(2,3)
Step-by-step explanation:
The solution to a linear system is always where both of the lines intersect.
let L = length and let W = width.
Use the equations 2L + 2W = 2750
and L = 5W + 15
Then do the steps as follows -
1. Plug the equation for what L equals into the first equation
2(5W+15) + 2W = 2750
2. Then distribute the 2
10W + 30 + 2W = 2750
3. Then add like terms
12W + 30 = 2750
4. Then subtract 30 from both sides
12W = 2720
5. Divide by 12 on both sides
W = 226.67
6. Then plug that into the second equation
L = 5(226.67) + 15
L = 1148.35 should be the answer
Correct!
When thinking of what determines a plane we can make the following comparison.
If a plane was the top part of a table, 3 legs, whose tops are points W, X and Y may hold it, as shown in the first picture.
but if the legs are in a line, as in the second figure, they may not hold the top part, so 3 collinear points cannot determine a plane.

Step-by-step explanation:
Harvey rides his bike at an average speed of 12 miles in 1 hour, 24 miles in 2 hours, and so on. Let h be the number of hours he rides and d be distance traveled. Write the equation for the relationship between distance and time in point-slope form.
----
You have three points relating time and distance:
(1,12),(2,24),(3,36)
-----
The slope for your equation would be (24-12)/(2-1) = 12/1 = 12
-------------------------------
The intercept is the distance you would travel in no time; that would be zero.
---------------------------------
The equation is: distance = 12(time)
d = 12t
