Answer: B
Step-by-step explanation:
Domain is x values
Range is y values
Domain you look from left to right. You can see it starts at -3, and it goes all the way to 2. NOT 4 BUT 2!! Since we are looking at the X.
Range.. WE ARE LOOKING AT THE LOWEST POINT!! LOWEST POINT FIRST!1 I cannot stress enough. The lowest y-value is -2, and it's maximum point is 4!
REMEMBER:
DOMAIN = X LEFT TO RIGHT
RANGE= Y LOWEST POINT TO HIGHEST
Answer:
Area = 21/2 = 10.5 area units
Step-by-step explanation:
Two of the points are on the same line (the y-axis) as they both have x-coordinates of 0. This can thus be the base of your triangle.
Two more are on the same line (y= -9) as they both have the same y-coordinate of -9. This can be the height of your triangle.
So you have a base which is between -2 and -9 (7 units) and a height which is between 0 and 3 (3 units) so now just use the equation for area of a triangle
If this is just a question to simply this equation, then here's the answer.
-10 + 4n -3t +2t +n
First, add together the n's: 4n+n = 5n
Then, the "t's": 2t - 3t = -t
Since there are no other numbers, you have:
-10 + 5n - t
