Answer:
Domain: [-2, 2]
Range: [-3, 3]
Step-by-step explanation:
Domain (x) is the left and right. Range (y) is the up and down.
It's a bracket if it is included, meaning, there is no gap or hole.
If it weren't included, it'd be a parentheses instead "( )". For example, if there was an open circle.
It would go to -infinty or +infinity if it were to go on forever, and that would be in parentheses.
EX: (-∞,∞) or (-∞, 8]
You can mix and match the brackets and parentheses depending on whether or not it touches/includes the number, like I've mentioned.
Answer:
i think it's 15 because if you use 5 and you have to do it by 3 it should be 15
The answers are in slope-intercept form, so you can see that the slope (coefficient of x) is only correct for choices b and c.
When you substitute x=3/2 into those equations, you find that b gives y=6 (correct) and c gives y=0 (incorrect).
The appropriate choice is ...
... b.) y = 2x+3
Answer:
25/72
Step-by-step explanation:
P( blue) = blue / total = 4/12 = 1/3
P ( blue, blue) = 1/3 * 1/3 = 1/9
P ( red) = red / total = 5/12
P ( red, red) = 5/12 * 5/12 = 25/144
P ( green) = green /total = 3/12 =1/4
P ( green , green) = 1/4 * 1/4 = 1/16
Add these together to get
P( same colour twice) = 1/9+ 25/144 + 1/16
=16/144 + 25/144 + 9/144
=50/144
=25/72
