Find the slope of the line that passes through the pair of points

Mathematics

Answer:

\frac{5,805}{2812}

Step-by-step explanation:

To find the slope from two points you can use the following formula:

m = \frac{y -y_{1} }{x -x_{1} }

Now substitute the two sets of points (\frac{7}{20}, \frac{5}{19} ) and (\frac{5}{9}, \frac{11}{16})

Substitute the values like this:

y = \frac{5}{19}, y_{1} = \frac{11}{16}, x = \frac{7}{20} and x_{1} =\frac{5}{9}

Now you will need to simplify the following expression:

m = \frac{\frac{5}{19} -\frac{11}{16} }{\frac{7}{20}-\frac{5}{9} }

Make sure that denominators are the same before substracting:

m = \frac{\frac{-129}{304} }{\frac{-37}{180} }

when you divide with a fractional number you only need to flip the second fraction over (find its reciprocal). Then just multiply:

m = (\frac{-129}{304} })({\frac{-180}{37} } ) = \frac{5805}{2812}

How would you "remove the discontinuity" of f ? In other words, how would you define
balu736 [363]
There is a hole at x=4 because the top factors to (x-4)(x+3)
in the end we get

f(x)=(x-4)(x+3)/(x-4)
the (x-4) cancels out and we get
f(x)=x+3
so baiscally f(x) is y=x+3 but with a hole at (4,7)


one way is to make a piecewise function defined as(x^2-x-12)/(x-4) for all x≠4 and defined as 7 for x=4

or, to just do f(x)=x+3

Mary weighs n kg while her sister weighs 15 kg less. How many times is Mary heavier than her sister?
kari74 [83]

Answer:

Mary is  \frac{n}{n-15}  times heavier than her sister

Step-by-step explanation:

Mary's Weight = n

Sister's Weight = n - 15

To find how many times mary is heavier, we need to multiply "that many time" [let it be x] with sister's weight to get Mary's weight.

<u>e.g. </u>If someone weighs 100 and another person 50, 50 * 2 = 100, thus, 100 kg person is 2 times heaving. We do same for this:

(n - 15) * x = n

x = n/(n - 15)
