Answer:
Solution: {(-1,-8), (0,-6)}
Step-by-step explanation:
y=x^2+3x-6 ............(1)
y=2x-6 ....................(2)
Solution:
by comparison, the right-hand sides of both equations are equal (to y)
x^2+3x-6 = 2x - 6
Transpose and simplify
x^2 -x = 0
x = -1 or x=0
Substitute x = -1 in (2)
y = 2(-1) -6 = -8 ..............(-1,-8)
substitute x = 0 in (2)
y = 2(0) -6 = -6 ...............(0,-6)
So there are two solutions, corresponding to the intersection of the quadratic and the straight line.

Answer:
The correct option is
a) Yes, because (0.95)(0.92) = 0.874
Step-by-step explanation:
An event is independent if the following condition is satisfied
Therefore, since the the probability that the answer can be found in Google = 0.95 and the probability that the answer can be found in Answers = 0.92
The probability that the answer can be found on both websites,
= 0.874
We check, P(A) × P(B) = 0.95×0.92 = 0.874 = = 0.874
Therefore, the possibilities of finding the event on the two websites is independent.
