First, find the distance between (-4, 0) and (-1, -3) by using the distance formula, you will get the √18
second, find the distance between (-4, 0) and (-3, 1), the result is √2
so the area is the √18*√2=6

Please refer to this website for the distance formula:

Statements are all TRUE

sinA = \frac{a}{c} and cosB = \frac{a}{c}


cscA = 1/sinA = 1/(a/c) = \frac{c}{a} and secB = 1/cosB = 1/(a/c) = \frac{c}{a}

tanA = \frac{a}{b} and cotB= 1/tanB = 1/ (b/a) = \frac{a}{b}

Tashia ate 1/3 of a pizza, and Jay ate 3/8 of the same pizza. What fraction of the pizza was eaten?
Sauron [17]
This is basically saying how much of the pizza did Tashia and Jay both ate, thus combining their portions together.

1/3 + 3/8 = fraction of pizza eaten

To add fractions, you must have a common denominator. Which is 24 in this case because 3*8 = 24.

So you multiply 1/3 with 8 and multiply 3/8 with 3.

1/3*8= 8/24
3/8*3= 9/24

Now you add the fractions.
8/24+9/24= 17/24. You add the numerator, the denominator stays the same.

17/24 of the pizza was eaten.

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.
