Answer:
Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis
Step-by-step explanation:
we know that
The rule of the reflection of a point across the x-axis is equal to
(x,y) -----> (x,-y)
That means ----> The reflected point will be located equidistant from the x-axis
so
Construct a line from A perpendicular to the x-axis
Determine the distance from A to the x-axis along this perpendicular line
Find a new point on the other side of the x-axis that is equidistant from the x-axis
therefore
A(-2,1) --------> A'(-2,-1)
The reflection point is A'
The distance of point A to the x-axis is equal to 1 unit
The distance from point A' to the x-axis is also 1 unit
Answer:
4
Step-by-step explanation:
3x-12=24
-12 to both sides
3x-12-12=24-12
3x=12
3x/3=12/3x
x=4
Answer: 5:15:23 pm
Step-by-step explanation:
There are different time zones in the world due to the Earth's rotation as this results in different parts of the Earth receiving sunlight at different times.
GMT is used as a basis to find the times of other zones.
In this instance, EDT time is -4 that of GMT.
This means that EDT is 4 hours behind GMT.
Time in GMT is therefore:
= 1:15:23 + 4 hours
= 5:15:23 pm
Answer:
y = 80+ 15*x
Step-by-step explanation:
members = initial membership + growth* months
y = 80+ 15*x
If you would like to know how many students will be allowed to attend recess on Friday, you can calculate this using the following steps:
7/8 of 24 students = 7/8 * 24 = 7 * 3 = 21 students
Result: 21 students will be allowed to attend recess on Friday.
