6 0

Answer:

B. Step 4 is incorrect , it should be \frac{10}{8}

Step-by-step explanation:

6x-1= -2x+9

Step 1

Collect like terms and change signs if you move anything from one side to the other; 6x+2x = 9+1

Step 2: Add like terms on both sides

8x = 10

Step 3: To remain with just x on one side, divide both sides by 8 and it becomes;

\frac{8x}{8} = \frac{10}{8}

The two 8s cancel each other and you remain with x=\frac{10}{8}

Which is 2logx-6log(x-9) written as a single logarithm
Elena-2011 [213]

Answer: option c.

Step-by-step explanation:

 To solve the given exercise and write the expression as a single logarithm, you must keep on mind the following properties:

m*log(a)=log(a)^m

log(a)-log(b)=log(\frac{a}{b})

Therefore, by applying the properties shown above, you can rewrite the expression given, as following:

2logx-6log(x-9)=logx^2-log(x-9)^6=log(\frac{x^2}{(x-9)^6})

Then as you can see, the answer is the option c.

Distance
Slav-nsk [51]

Answer: 28 km

Step-by-step explanation: For the first 25 minutes, he drove 60 km/h. Since there is 60 minutes in an hour, we know that he drove 25 km. The rest of the journey is 15 minutes. 15 minutes is 1/4 of an hour, so get 1/4 of 12 km/h. This would be 3 km. Add 25 km and 3 km. The distance between the 2 malls is 28 km.

Step-by-step explanation:

Since there is a set up fee of $20 then you would have to add it to the value of what 0.25p will be. Since p represents every square foot of the walls and you would multiply p by 0.25 every square foot is $0.25 then 0.25p+20 would accurately represent the problem
