8X+5Y=23
8X=23-5Y
-8X+9Y= -19 multiple all by -1
8X-9Y=19
8x=23-5y
Plug that in
23-5Y-9Y=19
-14Y=19-23
-14Y= -4
Y=1
8X=23-5Y
8X=23-5•1
8X=23-5
8X=18
X=18/8
X=9/4
Answer:
Its 4
Step-by-step explanation:
-4/3 ÷2/-6
first step is to keep -4/3 switch the division sign into a multiplication sign and reverse the second fraction from numerator/denominator to denominator/numerator.
so -4/3*-6/2=24/6=4
Answer:
a(8) = -0.0027
Step-by-step explanation:
The most general formula for a geometric sequence is a(n) = a(1)*r^(n-1), where a(1) is the first term and r is the common ratio.
Here, the formula becomes a(n) = 6*(-1/3)^(n-1).
Substitute 8 for n to find the eighth term:
a(8) = 6*(-1/3)^(8-1), or a(8) = 6(-1/3)^7, or a(8) = -0.0027
