Y + 2 =3 (x-6) find the slope and a point on the line​

Mathematics

Answer:

slope = 3, point = (6, -2)

Step-by-step explanation:

This is in point-slope form which looks like this : y-y1 = m(x-x1).

m is the slope, an x1 and y1 are the x and y coordinates of the point. Remember to flip the sign of the numbers for the points i.e. the y+2 in the equation becomes -2 for the point.

Maggie was doing research for her Ph.D. in physics when a 12 mg sample of radioactive material decayed to 3 mg in 26 minutes. De
netineya [11]

The general way to work this out is to solve the general expression for
the remaining quantity versus half-life, using logarithms.  But that's not
necessary with these numbers.

Look at the numbers:

-- 3 mg is  1/4  of  12 mg.

-- 1/4  is the product of  (1/2) x (1/2).

-- So the  3 mg is what's left of  12 mg after  2  half-lives.
The  26  minutes must be two half-lives.

-- The half-life of that substance is  26/2 = <em>13 minutes</em>.

Go Maggie !

Hi, can someone please help me out with this problem? thanks in advance.
kiruha [24]

Answer:

The following is an income statement using the Contribution format.

...........................Income Statement for Rivieremia Corp................................

Sales ........................................................................$1,500,000

Less Variable Costs................................................<u>($1,200,000)</u>

Contribution Margin..............................................$300,000

Less Fixed Costs....................................................<u>($200,000)</u>

Operating Income .................................................$100,000

Less Tax...................................................................<u>.($10,000)</u>

Net Income...............................................................$90,000

Tax = 10% * 100,000 = $10,000

Proving breakeven is $1,000,000.

The breakeven point for a company can be calculated by dividing the Fixed cost by the contribution margin ratio.

Contribution margin ratio = Contribution margin / Sales

= 300,000/1,500,000

= 20%

= Fixed Cost/ Contribution Margin ratio

= 200,000/20%

= $1,000,000

Degree of Operating Leverage = Contribution Margin/ Operating Income

= 300,000/100,000

= 3
