First step is to label at the top for the first pair as x1 and y1...then the next pair x2 and y2. ..so what u do is u subtract y2 from y1...and then draw a division line under as if u would divide..and x2 minus x1...and what that answer is for both while still the y answer over top and the x answer under u divide it..once u get the answer u have to put it in a point slope form...which is y-y1 =m(x-x1)..m is slope...u can pick any points which ever is best..and solve..also if u didn't know the y1 gets brought to the other side of the equal sign to go with x1,adding or subtracting depending on the number...it will end up being in slope intercept form of a equation..P.S. if the y1 is a negative compared with the equation it will be positive...ex..y--1=y+1..same goes with x

What percent of 60 is 51

vova2212 [387]

51=?
60 100

Then you cross-multiply the 51 and the 100 and get 5,100.

Next you take the 5,100 and divide it by the 60 which gives you your final answer of 85%.

Write in slope-intercept form an equation of the line that passes through the points (−5,−9) and (5,1).

o-na [289]

Answer:

y=x-4

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

m = (1--9)/(5--5)

m = (1+9)/(5+5)

= 10/10

= 1

The slope is 1

We have the slope and a point,so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1(x-5)

y-1 = x-5

Add 1 to each side

y-1+1 = x-5+1

y=x-4

This is slope intercept form (y= mx+b)

laiz [17]

We have been given that Avril invested $60,000 in a partnership with lane, Jules, Ray, Ravi and petra. The total investment of all partners was 320,000.

To find percentage of the business Avril owns we will find 60,000 is what percent of 320,000.

$\text{Percentage of business that Avril owns }=\frac{60,000}{320,000}\cdot100$

$\text{Percentage of business that Avril owns }=\frac{6}{32}\cdot100$

$\text{Percentage of business that Avril owns }=0.1875\cdot100$

$\text{Percentage of business that Avril owns }=18.75$

Therefore, Avril owns 18.75% of the business.

Wat the Pythagorean theorem

alexandr402 [8]

The Pythagorean theorem:

The theorem that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

<h2>The Pythagorean Theorem</h2><h3>Discoverer: Pythagoras</h3>

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. These calculations were discovered just as a tool of the ancient civilization of Babylonians who used it to divide up farmland; this was roughly 1,000 years before the birth of the discoverer, Pythagoras, a Greek philosopher.

The formula comes like this:
$a^2+b^2=c^2$
