the term relies on a product, meaning is a geometric sequence, and the product relies on a term's ordinal value to be plugged in, namely n = 7, you simply get the term by 
, when all it needs is the ordinal value to be plugged in, is called an explicit formula.
Any one shirt out of 4 can combine with any of the 4 socks
Number of combinations = 4 * 4 = 16
Answer:
x = -2, y = -3
Step-by-step explanation:
y - 3x = 3
x - 2y = 4
-3x + y = 3
x - 2y = 4
-6x + 2y = 6
x - 2y = 4
Add the equations.
-5x = 10
x = -2
Substitute -2 for x in the first original equation and solve for y.
y - 3x = 3
y - 3(-2) = 3
y + 6 = 3
y = -3
Answer: x = -2, y = -3
Answer:
- PQRS - a parallelogram
- GHJI - not necessarily
- RSUT - a parallelogram
- ABDC - a parallelogram
Step-by-step explanation:
A parallelogram has these characteristics that can be useful for answering this question:
- opposite sides are the same length
- opposite sides are parallel
- the diagonals bisect each other
__
<h3>PQRS</h3>
Opposite sides are the same length: a parallelogram
__
<h3>GHJI</h3>
Two isosceles triangles share a base segment. Not necessarily a parallelogram.
__
<h3>RSUT</h3>
The diagonals bisect each other: a parallelogram
__
<h3>ABDC</h3>
Opposite sides are parallel: a parallelogram. We know BD║AC from the converse of the alternate interior angles theorem. AB and CD are marked parallel.
