Answer:

x = -1

Step-by-step explanation:

The vertex is halfway between the focus and the directrix.

So here the directrix is  a vertical line  to the left of the vertex and passing through the point (2-3, 9) = (-1, 9)

It is x = -1.

Let A and B be two disjoint events such that P(A) = .30 and P(B) = .60. What is P(A and B)? 0.18 0.72 0.90 0 none of the above

Answer:

0

Step-by-step explanation:

If two events are disjoing (aka mutually exclusive) that means that there is 0 overlap or the intersection equals 0

So the probability of A <em>and </em>B occuring is 0 (because P(A∩B)= 0)

nlexa [21]

Answer:

The answer is G. y=2x-2

Step-by-step explanation:

y+6=2(x+2)

First you multiply 2 by what is in the parenthesis

y+6=2x+4

Next you get y by itself by subtracting 6

y=2x+4-6

Simplify

y=2x-2
