If the discriminant is negative no real solution exists.
If the discriminant is equal to 0 only one real solution exists.
If the discriminant is positive 2 real solutions exist.
The discriminant:
D = b² - 4 a c
1 ) - 7 x² + 6 x + 3 = 0
D = 6² - 4 · ( - 7 ) · 3 = 36 + 84 = 120 > 0
Answer: b) two solutions
2 ) - 8 x² - 8 x - 2 = 0
D = ( - 8 )² - 4 · ( - 8 ) · ( - 2 ) = 64 - 64 = 0
Answer: a ) one solution
Answer:
Selling price= $1.14
Step-by-step explanation:
Giving the following information:
Purchase cost= $0.95
Mark up percentage= 120% = 1.2
Selling price= $1.14
Selling price= purchase cost * mark up percentage
Selling price= 0.95 * 1.2
Selling price= $1.14
