-3,-7.5,2 2/3 are the opposites of those numbers
Answer:
reflex angle
Step-by-step explanation:
Acute is less than 90
Right = 90
Obtuse is greater than 90 and less than 180
Straight is 180
Reflex is greater than 180 and less than 360
This is greater than 90 and less than 180 so it is a reflex angle

Answer:
(2,7) is not a solution to the given system of equations.
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
