Answer:

(x, y) = (4, 0)

Step-by-step explanation:

It looks like you want to solve ...

x - y = 4
x + y = 4

Adding the two equations gives ...

2x = 8

x = 4 . . . . divide by 2

Then ...

y = 4 - x = 0

The solution is (x, y) = (4, 0).

_____

If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.

Use the arc length formula and the given information to find r. Show your work for full credit. s = 8.1 ft θ = (3.14/3)rad r = ?

VladimirAG [237]

This question is simple I'm a little confused on the specifics so I will try my best to help.

s=θ(r)
arc length = angle x radius
2.46888m(or 8.1 ft) = (π/3) x r
$r = (\pi /3)/2.46888$
$r = .425m$

To find the coordinates of point L, the midpoint of JK, the equation M = can be used. What are the coordinates of point L? L(1,

anygoal [31]

Since we are already given with the formula to solve for the coordinates of point L, all we have to do is to perform the necessary operation in the item. The formula for the coordinates of the midpoint is, M = ((5 + 1) / 2 , (3 - 7) / 2)performing the operation, M = (3, -2)Thus, the coordinates of point L are (3,-2).
