Answer:
A. 2 distinct roots.
Step-by-step explanation:
2x^2 + 8x + 3 = 0
Finding the discriminant:
b^2 - 4ac = 8^2 - 4 * 2 * 3
= 64 - 24
= 40
The discriminant is positive but not a perfect square
So there are 2 distinct ,real, irrational roots.
Answer: straight line across on the y axis on -2/3
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
if x= number of hours replace the x by 9
so you have 5×(1.50)^9+10=
5×(192.21)+10 = 202.21 so 202 will be nearest whole number
Answer:
C
Steps
The A equation is impossible (even if it looks like solvable with quadratic formula)
