Answer:

(-10, 0) and (0,-5)

Step-by-step explanation:

For the function $f(x)=-\dfrac{1}{2}x-5,$ find x-intercept and y-intercept:

1. when y=0, then

$0=-\dfrac{1}{2}x-5,\\ \\\dfrac{1}{2}x=-5,\\ \\x=-10;$

2. when x=0, then

$y=-\dfrac{1}{2}\cdot 0-5,\\ \\y=-5.$

You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function $f(x)=-\dfrac{1}{2}x-5.$

A2+b2 = C2solve for a

lesantik [10]

$a^2+b*2=c^2$

$a^2+2b=c^2

$ $\text{Regroup terms}$

$a^2=c^2-2b
$ $\text{Subtract 2b from both sides}$

$a=\pm \sqrt{c^2-2b}$ $\text{Take the square root of both sides}$

How do I find mean median range iqr and standard deviation

ycow [4]

Answer: to find the mean add the numbers that were given then Divine by the amount of numbers you added. To find the median put all the numbers in numerical order and pick the middle one if it is an even amount of numbers than you pick the number exactly halfway between the two middle. To find the range you see how many numbers are repeated in which ever number is repeated the most amount of times that is the range.
