Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
Answer: (3, 2), (2, 3)
The correct answer is 39 units.Parameter is the
sum of the lengths of all sides of a polygon.
The sides of the polygon are PT, TS, SR, RQ,
and QP.
Answer:
No, it's not a counterexample, because 48 is a multiple of 8
Step-by-step explanation:
I think like 4 x 3 + 8 x 2 = 28 is a counterexample, because 28 is not a multiple of 8.
So, for each one you are trying to complete a full rotation or 360°. This means that you should add up all of the numbers and subtract that from 360.
#1. 360-279=81°
#2. 360-281=79°
