-22 > -5x - 7 > = -3
equivalent one is :
a. -5x - 7 < -22 and -5x - 7 > = -3
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
Answer:
square
Step-by-step explanation:
Answer: 13/24
Step-by-step explanation:
Number of leather belts = 4
Number of plastic belts = 3
Number of canvas belts = 10
Number of rubber belts = 6
Number of denim belt = 1
Total belts = 24
The probability of choosing a plastic belt and then a canvas belt will be:
= P(plastic) + P(canvas)
= 3/24 + 10/24
= 13/24
