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
The answer to the question
Answer:
2.1
Step-by-step explanation:
Your answer is correct. Good job.
Some types of transformations producetranslations, and others do not. Thetransformation (x, y) → (2x, 2y) is shown inFigure 5.1-3 for □ GHJK. Notice that point Gdoes not move, but the other points move awayfrom the origin. The result is a square twice aslarge as the preimage. For the followingreasons, this transformation is not a translation:the vertices do not all follow the same vector,and the image is not the same size as thepreimage
