Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.
Hope this helps.
Step by ... 8*x^2+7*x-15-(-7)=0 ... 3.2<span>Solving 8x2</span>+7x<span>-8 = 0 by Completing The Square .</span>
X + 2y = 6
2y = -x + 6
y = -1/2 x + 3 so slope = -1/2
parallel lines has same slope = -1/2
perpendicular lines slope is opposite and reciprocal so slope = 2
if slope not equal either -1/2 or 2 then neither.
y = -1/2 x - 5 ....m= - 1/2.... parallel
-2x + y = -4
y = 2x - 4...m = 2 ....perpendicular
-x + 2y = 2
2y = x + 2
y = 1/2 x + 1 ...m = 1/2 ...neither
x + 2y = -2
2y = -x - 2
y = -1/2 x - 1 ...m = -1/2 .....parallel
hope it helps
Answer:
201
Step-by-step explanation:
First you need to know the position to term rule and to find this you use a formula which is:
tn = an + b
Where tn is the term number, a is the difference between the other terms.
So the tposition to term rule here is 4n+1.
Then we substitute n for the value 50 making it 4(50) + 1 = 201.
201 is the 50th term
It will be d at least i think
