Answer:
D
Step-by-step explanation:
Given the quadratic
d = - 16t² + 12t ← subtract d from both sides
- 16t² + 12t - d = 0 ← in standard form
with a = - 16, b = 12, c = - d
Use the quadratic formula to solve for t
t = ( - 12 ± ) / - 32
= ( - 12 ± ) / - 32
= ( - 12 ± ) / - 32
= ( - 12 ± 4) / - 32
= ±
= ±
= ±

y = 3x - 2
x + y = 6
x + 3x - 2 = 6
4x - 2 = 6
4x = 6 + 2
4x = 8
x = </span>
x = 2
Hence, the x co-ordinate is 2.
y = 3x - 2
x + y = 6
x + 3x - 2 = 6
4x - 2 = 6
4x = 6 + 2
4x = 8
x = </span>
x = 2
Hence, the x co-ordinate is 2.
