What is the slope of A(8,-3) B(-4,-12)

allochka39001 [22]

Answer:

$m=\frac{3}{4}$

Step-by-step explanation:

In order to solve for a slope, you must in the formula,

$slope=\frac{rise}{run} = (\frac{y_{2} -y_{1} }{x_{2} -x_{1} } )\\ \\where...\\(x_{1} ,y_{1} )and(x_{2} ,y_{2} )$

<u><em>(In this case, you can choose which point can have the x(1) and y(1) and which can have the x(2) and y(2)</em></u> )

1.) Plug the numbers for x(1), x(2), y(1) and y(2)

2.) Solve and simplify the number, which you should get

$m=\frac{3}{4}$

Half of a herd of deer are grazing in the field and three-fourths of the remaining are playing nearby. The rest 9 are drinking w

aksik [14]

Answer:

Step-by-step explanation:

We'll work through this part by part. Half are grazing, and half are not. The half that are not are then cut into fourths. 3/4 of this non grazing half are playing so that leaves 1/4 drinking, which it tells us is 9.

so, if 9 is 1/4, 18 is 2/4 and so on. So 36 is the full number of the half not grazing. So if 36 is one half, the whole group is 72.
