Answer:

D.

Step-by-step explanation:

A.

9 (x - 3) = 9x - 27 ➡ 0 = 0 (this has infinite solutions)

B.

9x - 3 = 9x - 3 ➡ 0 = 0 (has infinite solutions)

C.

9x - 3 = 27x - 3 ➡ x = 0 (has one solution)

D.

9 (x + 3) = 9(x + 10) ➡9x +27 = 9x +90➡ 9x -9x = 90 - 27 ➡ 0 = 63 (doesn't make sense so it has no solution)

Which expression is equivalent to
nirvana33 [79]

For this case, we must find an expression equivalent to:

\frac {-9x ^ {- 1} y ^ {- 9}} {- 15x ^ 5y ^ {- 3}}

By definition of power properties we have:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

Rewriting the previous expression we have:

The "-" are canceled and we take into account that:

\frac {9} {15} = \frac {3} {5}

So:

\frac {3} {5x^5 * x ^ 1 *y ^ 9* y ^ {- 3}} =

According to one of the properties of powers of the same base, we must put the same base and add the exponents:

\frac {3} {5x ^ {5 + 1} * y ^ {9-3}} =\\\frac {3} {5x ^ 6 * y ^ 6}

Answer:

\frac {3} {5x ^ 6 * y ^ 6}

Option B

Find P(A or B) if the events are disjointed. P(A) =6/25 , and P(B) =9/25 .
nevsk [136]
Here, "disjointed" signifiies that Event A and Event B are independent; neither outcome influences the other.  In such a case, the union of A and B is given by the sum of the two probabilities P(A) and P(B).

Here, that sum is P(A or B) = 6/25 + 9/25, or 15/25, or 0.6.
