Answer:
D. This quadratic equation two complex solutions.
Step-by-step explanation:
Equating it with
a = 5, b = 6, c = 2
is negative.
Therefore, this quadratic equation two complex solutions.
D) because if the probability it lands on a 2 is 1/5, it means out of 5 numbers, only one is a 2. Thus, the other 4 must be not a 2. So when it asks "<span>What is the probability that the spinner will land on a number other than 2?" the answer is 4/5</span>
The parabola opens in the direction of the focus.
Since the focus is above the vertex, it opens up.
Ok so if you notice every choice is solved for a, all you have to do is isolate "a" in 7a-8b=10x. Start by moving 8b to the other side and to change the sign. Now it is 7a = 10x + 8b. Then divide everything by 7 and you get a = (10x + 8b)/7
23×8= 184
The answer is 184
