Answer:
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
equation:
3x -4
Answer:
76
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0, then
the discriminant Δ = b² - 4ac
Given
3x² - 10x = - 2 ( add 2 to both sides )
3x² - 10x + 2 = 0 ← in standard form
with a = 3, b = - 10 and c = 2
b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
