Answer:
x = 10°
Step-by-step explanation:
ZA + ZB = 90°
50° + 4x = 90°
4x = 90° - 50°
4x = 40°
x = 10°
Answer: The axis of symmetry is x = –4.
The domain is all real numbers.
The x-intercepts are at (–6, 0) and (–2, 0).
Step-by-step explanation:
Step-by-step explanation:
y = y
x - 2 = 2x - 3 - 3x²
3x² + x - 2x = - 3 + 2
3x² - x = - 1
.
a = 3, b = -1, c = 0

.
Substitution :
y = x - 2
y = ⅓ - 2
y = ⅓ - 6/3
y = - 5/3
y = - 1 ⅔
