Step 1: Given

Step 2:  Distributive Property

Step 3: Addition Property of  Equality

Step 4: Division Property of  Equality

Step-by-step explanation:

We need to match the reason with the correct step in the equation.

Equation:

Given:

2x = -4(x-3)

Applying Distributive property a(b+c)=ab+ac

2x=-4x+12

Now, Applying addition property of equality:

Adding +4x on both sides

2x+4x=-4x+12+4x\\6x=12

Now, Applying Division property of Equality:

Divide both sides by 6:

\frac{6x}{6}=\frac{12}{6}\\x=2

So, Answer will be:

Step 1: Given

Step 2:  Distributive Property

Step 3: Addition Property of  Equality

Step 4: Division Property of  Equality

Simplify the expression –3(x + 3)2 – 3 + 3x. What is the simplified expression in standard form?
andrew11 [14]

For this case we must simplify the following expression:

-3 (x + 3) ^ 2-3 + 3x

We solve the parenthesis:

-3 (x ^ 2 + 2 (x) (3) + 3 ^ 2) -3 + 3x =\\-3 (x ^ 2 + 6x + 9) -3 + 3x =

We apply distributive property to the terms within parentheses:

-3x ^ 2-18x-27-3 + 3x =

We add similar terms:

-3x ^ 2-18x + 3x-27-3 =\\-3x ^ 2-15x-30

Answer:

-3x ^ 2-15x-30

If log2 5 = k, determine an expression for log32 5 in terms of k.
lukranit [14]

Answer:

log_3_2(5)=\frac{1}{5} k

Step-by-step explanation:

Let's start by using change of base property:

log_b(x)=\frac{log_a(x)}{log_a(b)}

So, for log_2(5)

log_2(5)=k=\frac{log(5)}{log(2)}\hspace{10}(1)

Now, using change of base for log_3_2(5)

log_3_2(5)=\frac{log(5)}{log(32)}

You can express 32 as:

2^5

Using reduction of power property:

log_z(x^y)=ylog_z(x)

log(32)=log(2^5)=5log(2)

Therefore:

log_3_2(5)=\frac{log(5)}{5*log(2)}=\frac{1}{5} \frac{log(5)}{log(2)}\hspace{10}(2)

As you can see the only difference between (1) and (2) is the coefficient \frac{1}{5} :

So:

\frac{log(5)}{log(2)} =k\\

log_3_2(5)=\frac{1}{5} \frac{log(5)}{log(2)} =\frac{1}{5} k

A woman has 7 keys. only one of them will open her door. when seh arrives at the door there is no sufficient light for her to fi
Gala2k [10]
Since she has seven key the probability that the first one will open the door is
\frac{1}{7}
if it takes three attempts to open the door,the probability is
\frac{1}{3}
if the three attempts would not work
then the probability that the fourth attempt will open the door is
\frac{1}{4}
hope this helps
