Answer:
6 and -8
Step-by-step explanation:
Solve:
xy = 48
x + y = -2
You can say y = -2-x = -(x+2) and then substitute that in the first:
-x(x+2) = 48
-x² -2x - 48 = 0
x² + 2x + 48 = 0
Quadratic formula can do the rest if you don't "see" the factorization.
The answer to this question is A. : )
Answer:
not similar
Step-by-step explanation:
5/10 of the numbers between 1-10 are even and not odd. Therefore P(not even)=1/2
How to get answer by Mimiwhatsup:
Let's solve for b.
1/t = 1/a + 1/b
Step 1: Multiply both sides by t.
1= at+bt/ab
Step 2: Multiply both sides by ab.
ab=at+bt
Step 3: Add -bt to both sides.
ab+−bt=at+bt+−bt
ab−bt=at
Step 4: Factor out variable b.
b(a−t)=at
Step 5: Divide both sides by a-t.
b(a−t)/a−t = at/a−t
b= at/a−t
