Slope: \frac{-7-2}{13+2}

-7 - 2 = -9

13 + 2 = 15

Slope = -\frac{9}{15}

Slope is change in y over change in x.
So in this case, it would be 2- -7/-2-13 = 9/-15 = -3/5.

The answer is -3/5.

What is 7/25 in decimal form
timama [110]

Every fraction is just a short way to write a division.
Whenever you see a fraction, it means

            the top number
divided by
            the bottom number.

When you actually do the division, like with a pencil or a calculator,
the quotient you get is the decimal form of the fraction.

I won't insult your intelligence by giving you  7  divided by  25 .
I'm sure you can do that easily.

I also won't insult your intelligence by sending you to a web site.
I assume that if you were on a desert island without your phone
or any 4G coverage, you'd be able to figure out a way to divide
7 by 25.

I am currently working on Trigonometry, but unfortunately I am having a hard time. Here are some of my questions I've answered s
Novosadov [1.4K]
\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}\\\\
-------------------------------\\\\
cos(\theta)=\cfrac{\sqrt{3}}{3}\cfrac{\leftarrow adjacent=a}{\leftarrow hypotenuse=c}
\\\\\\
\textit{using the pythagorean theorem}\implies c^2=a^2+b^2\implies \pm\sqrt{c^2-a^2}=b
\\\\\\
\pm\sqrt{3^2-(\sqrt{3})^2}=b\implies \pm\sqrt{6}=b

now the root gives us the +/-, which is it? well, we know the sine is negative, so the "b" value must be negative, so it has to be -√6 = b

thus  \bf sin(\theta)=\cfrac{opposite}{hypotenuse}\implies sin(\theta)=-\cfrac{\sqrt{6}}{3}

–6m –8 = 24 what is m
GuDViN [60]
Hi there....

-6m - 8 = 24
-6m = 24 + 8
-6m = 32
m = 32/-6
m = -16/3
or if they ask you for decimal, it will be m= -5.33
