Answer:
Step-by-step explanation:
x^3-8=0
x^3=8
x^3= 2^3
x=2
147/14=%10.5, .105*84=8.82. the answer is $8.82.
Answer: (0, 1), (-1, -3)
Given two equation's:
- y = 2x² + 6x + 1
- y = −4x² + 1
<u>Solve them simultaneously</u>:






(a) When x = 0, y = −4(0)² + 1 = 1
(b) When x = -1, y = -4(-1)² + 1 = -3
Solution: (x, y) → (0, 1), (-1, -3)
