Answer:
symmetry about the y-axis is shown
Step-by-step explanation:
Points on the right of the line of symmetry (x=0, the y-axis) are the same distance from that line as the corresponding points on the left. (That is what makes it a line of symmetry.)
There is no point of rotation that will map one figure to the other after rotation, hence no point or rotational symmetry.
Answer:
2.5
Step-by-step explanation:
Basically, you take your total of $9.25 and subtract $1.75. That gives you $7.5 so then you divide by 3 which gives you your answer: $2.5
Answer:
1.) Yes, it is a function
2.) No, it is not a function.
Step-by-step explanation:
1.) It is a function because none of the numbers in the x-axis repeat.
2.) It is not a function because the numbers in the x-axis repeats 0 three times.
To do the mean of the numbers, you have to add them all together and divide them by the number of numbers:
65 + 125 + 90 + 100 = 380
There are 4 numbers, so you have to do
380 ÷ 4 = 95
The mean of those numbers is 95
How many times does 2 go into 7. find that out and you will know
