The answer to this is to try the hardest you can! I believe in you :)
Answer:
C.
Step-by-step explanation:
In a function, one x-value must have just one y-value assigned to it. So in short, C is the only table that does not represent a function because it has two values of Y (-3, and -1) for one value of x (1).
Answer
9/20
Step-by-step explanation:
This is a probabilty, problem
firstly, let us bring out the sample space and size
the sample space is
9 apples,
5 bananas,
1 orange, and
5 peaches
The sample size is (9+5+1+5)= 20
The probability of picking a banana is
Pr(banana) =5/20
=1/4
The probability of picking an apple
Pr(apple) = 9/20
The probability of picking up a banana and an apple with replacement is
=1/4+9/20
=9/80
Answer:
x = 9
Step-by-step explanation:
1) Subsitute! You have to replace y with 2x - 2 in 3x -y = 7, b/c they already gave you the equation for y (in the second part: y = 2x - 2)
So, your equation would look like this : 3x - (2x - 2) = 7
3) Solve suing PEMDAS!
There's a negative outside the parenthesis of 2x -2 -> - (2x-2). Multiply the negative individually inside the parenthesis so you will get (-2x + 2)
3x - 2x - 2 = 7 subtract the same variable; x
1x - 2 = 7 you don't need to put 1 to x, only if you want!
+ 2 + 2 add 2 on both sides
x = 9
Answer:
The Y values RANGE from -9 through 9, so the range is 18
