-2(1-7n)-5n=34
Multiply the bracket by -2
(-2)(1)=-2
(-2)(-7n)=14n
-2+14n-5n=34
-2+9n=34
Move -2 to the other side. Sign changes from -2 to +2.
-2+2+9n=34+2
9n=34+2
9n=36
Divide by 9 for both sides
9n/9=36/9
n=4
Answer: n=4
This is what the graph looks like hope this helps:)
Answer:
The other endpoint of the segment is
.
Step-by-step explanation:
The midpoint of the points
and
is given by the following formula:

where
= coordinates of the midpoint.
We know that the midpoint is (-15, 2) and an endpoint is (-12, 11). Substituting the information we have gives:

To find
we need to solve this equation:

and to find
we need to solve this equation:

The other endpoint of the segment is
.
Answer:
y=5/2
Step-by-step explanation:
the length of the bottom side is 17-3 = 10
to be a square all sides need to be 10 units.
