Answer:
Step-by-step explanation:
Read the coordinates of the points:
A(-1, 0) → A'(-1, 0)
B(0, 2) → B'(0, -2)
C(3, 2) → C'(3, -2)
D(4, 0) → D'(4, 0)
(x, y) → (x, -y)
Check:
A → A': (-1, 0) → (-1, -0) = (-1, 0) CORRECT
B → B': (0, 2) → (0, -2) CORRECT
C → C': (3, 2) → (3, -2) CORRECT
D → D': (4, 0) → (4, -0) = (4, 0) CORRECT
Answer:
The avergae temp rose 51° F.
Step-by-step explanation:
Average temp in January = -8°F
Average temp in March = 43°F
-8 is 8 away from 0 (absolute value)
43 is 43 away from 0 (absolute value)
43 + 8 = 51
The average temp rose 51°F
Answer:
c
Step-by-step explanation:
30°+90°+x=180° (the sum of interior angle of a triangle is 180°)
120°+x=180°
x=180°-120°
x=60°
Step-by-step explanation:
Diameter = 2x Radius
Radius = 1/2 Diameter
