Answer: (x, y) transforms into (-x, y)
Step-by-step explanation:
When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.
So if we do a reflection over the y-axis, then the value of y must be fixed.
So if we start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)
So the rule is, the y value remains equal and the x changes of sign.
1-
number 2) is correct
2- 3) is true
11) Jacob is not correct. because 6radical 5 is irrational
12) radical 20 is an irrational number but
so a+b is irrational
but

so b+c is rational
good luck
Events
• A: an even number is rolled in the first time
,
• B: a number greater than 3 is rolled the second time
The probability of rolling an even number is:

The probability of rolling a number greater than 3 is:

Events A and B are independent, then the probability of one happening after the other is:
Answer:
a=24000/120=200
Step-by-step explanation:
area= a*b
Area=24000
a=120
b=200
