Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term 
can be obtained as the previous term 
by a constant value called the common ratio.
or equivalently
Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6
Answer:
Step-by-step explanation:
d(x)=√((x-2)2+(y-0)²)
=√((x-2)²+y²)
=√((x-2)²+(x-1)²)
=√(x²-4x+4+x²-2x+1)
=√(2x²-6x+5)
D=d²(x)=2x²-6x+5
Answer:
The first step to solve the equation below is to first distribute the 2 to (x+7)
Step-by-step explanation:
2 (x+7) = -4x + 14
2x + 14 = -4x + 14
Hey friend!
Let's figure this out!
P(−5, −6)
reflect about y axis
Q(5, -6)
reflect about x axis
R(5,6)
So that gives you the answer!
3. Q(−5, 6) and R(5, −6)
Hope this helped!
