Quartile 1 is 211. quartile 2 is 226 , and quartile 3 is 265.5
Answer:
x = 6
∠B = 126
Step-by-step explanation:
∠A = ∠B through alternate interior angles
∠A = ∠B
8x + 78 = 2x + 114
8x - 2x = 114 - 78
6x = 36
x = 36 ÷ 6
x = 6
∠B = 2x + 114
2(6) + 114
12 + 114
= 126
Step-by-step explanation:
Axis of symmetry for quadratic ax² + bx² + c:
x = -b/2a.
Therefore for y = x² - 4x + 2,
-b/2a = -(-4)/2(1) = 2
The axis of symmetry is x = 2.
