Answer:
5
Step-by-step explanation:
Answer:
B. C is parallel to D.
Step-by-step explanation:
since lines 1 and 3 are congruent it means they have the same shape and size, They lie in the same plane and they are both lines. However lines 1 and 3 which is C and D never intersect, therefore they are parallel.
The expression is an illustration of the summation notation
The expanded form of the summation notation
is 0^4 + 1^4 + 2^4 + 3^4+4^4
<h3>How to determine the expanded form</h3>
The summation notation is given as:

The above summation notation represents the sum of the numbers raise to the power of 4, from 0 to 4
So, we have:

Hence, the expanded form of
is 0^4 + 1^4 + 2^4 + 3^4+4^4

Answer:
x=7, y=-1. (7, -1).
Step-by-step explanation:
2x+4y=10
-2x+y=-15
-----------------
5y=-5
y=-5/5
y=-1
2x+4(-1)=10
2x-4=10
2x=10+4
2x=14
x=14/2
x=7
