$log_{2}x -log_{4}x= -2 \\ \\ log_{2}x -\frac{log_{2}x}{log_{2}4}= -2 \\ \\ log_{2}x*(1-\frac{1}{log_{2}4})=-2 \\ \\ log_{2}x*(1-\frac{1}{2})=-2 \\ \\\frac{1}{2}*log_{2}x=-2 \\ \\ log_{2}x=-4, \\ \\ x=2^{-4} = \frac{1}{2^{4}}=0.0625$

Please help me with this one question! Any help is welcomed, thanks in advance!

Point slope form is y - y1 = m(x - x1)

so if the slope is m= 2 and (x1,y1) = (1,3) is a point on the line the equation is:-

y - 3 = 2(x - 1)

Sam and Paul started a business. Their investments were in the ratio 6:7, respectively. How much did Paul invest if Sam's invest

Pani-rosa [81]

Answer:

$966

Step-by-step explanation:

Sam's investment = 828

Paul's investment will be temporarily marked as x.

We need to divide 828 by 6 = 138 to find the result, x.

We multiply that by 7. 7 x 138 = 966.

We can write in 3 different ways:

828 : 966

828/966

(or in fraction form, I don't have a fraction line.
