Step-by-step explanation:
-3 is the slope of the two points
First off, do a prime factoring of the constant and leading coefficient, namely 9 and 8 respectively.
so a prime factoring of 8 is 2*2*2, and a prime factoring of 9 is 3*3.
so, those are the factors... now, how do we produce products that gives us the middle coefficient +18?
well, let's see hmmmm 2 * 3 * 3 and 2 * 3....so that's 18 + 6, that's 24.. .so... no good is not 18, let's try again.
2*2*3 and 2 * 3, so that's 12 + 6, now, that's +18
so we'll use those, 2*2*3 and 2*3, or 4 * 3 an 2 * 3, (4x + 3)(2x + 3) = 0.
Answer:
5/14
Step-by-step explanation:
P(A or B) = P(A) + P(B) − P(A and B)
25/28 = 23/28 + 12/28 − P(A and B)
P(A and B) = 10/28
P(A and B) = 5/14
A) I believe but you might not want to go with it cause I'm not good at math AT ALL:)
