Answer:
-6/(v^2 -8)
Step-by-step explanation:
(-6u - 9)/(v^2 -8) + (6u + 3)/(v^2 -8)
Since we have common denominator terms, we can add both fraction terms
(-6u+6u -9+3)/(v^2 -8)
Now we have
-6/(v^2 -8)

Answer:
(x, y) = (61/23, 36/23)
Step-by-step explanation:
We assume you intend the equations to be ...
Then in general form, they are ...
5x -4y -7 = 0
2x +3y -10 = 0
The solution using the "cross multiplication method" is ...
1/(15 +8) = x/(40+21) = y/(-14 +50)
(x, y) = (61/23, 36/23)

<em>Comment on "cross multiplication method"</em>
When the coefficients from the general form equations are written as a 2×4 array with the first and last columns the same ...
the solution is 1/d1 = x/d2 = y/d3, where d1, d2, d3 are the determinants of successive pairs of columns.
- d1 = (5)(3) -(2)(-4)
- d2 = (-4)(-10) -(3)(-7)
- d3 = (-7)(2) -(-10)(5)
Answer:
12
Step-by-step explanation:
60% of $12
(60 × 20) ÷ 100 = 12
The reflexive property of equality simply states that a value is equal to itself.
