Answer:
(-2,4)
Step-by-step explanation:
Since this is a system of equations, just look where the two lines intersect.
In this case, the intersecting pair is: (-2, 4)
Answer:
Step-by-step explanation:
Use the fact that C + 118 = 180 Subtract 118 from both sides
C + 118 - 118 = 180 - 118
C = 62
C + 57 = B C and A are remote interior angles. They equal the exterior angles that are not supplementary to B.
62 + 57 = B
B = 119
Answer:
5/6
Step-by-step explanation:
Perpendicular lines just have the opposite slope.
Answer:
A. 3, 4, 5
Step-by-step explanation:
Option A:
LHS = 3² + 4² = 9 + 16 = 25
RHS = 5² = 25
(3, 4, 5) is a right triangle.
Option B:
LHS = 7² + 8² = 49 + 64 = 113
RHS = 9² = 81
(7, 8, 9) is NOT a right triangle.
Option C:
LHS = 3² + 9² = 9 + 81 = 90
RHS = √95² = 95
(3, 9, √95) is NOT a right triangle.
