Umm.. I have to see the problems, we might not have the same textbooks so
{y=3x+1 |*5
{y=5x-3 |*(-3)
{5y=15x+5
{-3y=-15x+9
+___________
2y=14
{y=7
{7=3x+1
{3x=6
{y=7
{x=2
{y=7
The answer: C
:)
If it's a regular octahedron, then you can calculate it using the formula
where
is the length of the edge.
If it's not regular, you have to calculate the area of each side individually.
Answer:
Both the mean and median will increase, but the mean will increase by more than the median.
Step-by-step explanation:
We have that Options That are correct are given as
From the question we are told
Which of the following is true for this image?
a. CD is the perpendicular bisector of AB
b. Neither line segment is a perpendicular bisector.
c. AB is the perpendicular bisector of CD
d. both line segments are perpendicular bisectors.
Generally
- CD is the perpendicular bisector of AB
This is True Because CD Cuts Across AB at angle 90 in the middle
- Neither line segment is a perpendicular bisector.
This is Untrue Because CD Cuts Across AB at angle 90 in the middle
- AB is the perpendicular bisector of CD
This is True Because AB Cuts Across CD at angle 90 in the middle
- Both line segments are perpendicular bisectors.
This is True
