Answer:
n = 5.75
Step-by-step explanation:
original equation
n - 31/4 = 2
multiply everything by 4
n * 4 - 31/4 * 4 = 2 * 4
simplify
4n - 31 = 8
add 31 to both sides
4n - 31 + 31 = 8 + -31
simplify
4n = -23
divide both sides by 4
4n/4 = -23/4
simplify
n = 5.75
Answer:
X=-6
Step-by-step explanation:
Subtract 9 on both sides
Add -9 and -15 You get -24
Divide -24 by 4 you get x=-6
Radius is half of diameter so the diameter would be so 1.5 and 6. And circumference is 2(pi)(radius). So that's around 9.4 for the first question and 38 for the second
44-36=8

Answer:
In x-axis:
, In y-axis: 
Step-by-step explanation:
The rule of the reflection of a point across the x-axis is as shown:
The reflection of the point
across the x-axis is given by
.
The point given to us is
, when reflected across the x-axis we get:

Now, when a point
is reflected across the y-axis we get the point
.
So when the point
is reflected across the y-axis we get:
.
