I can’t really help you too much with the graphing but what you do with ordered pairs is whatever is the first number (example for point A it’s -2) you go and find it on the horizontal line. Once you find it on the horizontal line you either go up or down the graph by how many units the second number is (4 so you would go up four in the graph) and then you plot the point
Just answer each one to the best of your ability... study the graph and say what’s happening, like so many gallons per hour or something like that
Answer:
-6
Step-by-step explanation:
Plug in (-1) for y: -3(-1) - 9
Simplify: Negative x Negative = Positive
-3(-1) = 3 so... 3-9
3 - 9 = -6
-3y - 9 is equivalent to -6
Answer:
To the first picture: it's 9
To the second: its sin3/5
Step-by-step explanation:
This would take some time to explain so I'll keep it brief
Pic 1) process of elimination through cos
Pic 2) You divide the opposite by the hypotenuse to get the degree of angle x
C. volume
a pint is a unit of fluid volume equal to one-eighth of a gallon
