Answer:
The common ratio is
The next term in the sequence is 2
Step-by-step explanation:
In a geometric sequence, the common ratio is the constant value you multiply a term by in order to find the value of the following term. Therefore, it is mathematically calculated as the quotient between a term and the term immediately before it. And it is in fact That is:
common ratio
This quotient should be true for any two consecutive terms in the sequence.
so using the first two terms, we find:
You can test that this common ratio is true for all other terms listed:
So now, in order to find the term that follows, all we need to do is to multiply the last term given (8) by this common ratio:
Answer:
D. It has a single solution: x=-3, y= 26.
Step-by-step explanation:
3x + y=17
Subtract 3x so it is in y=mx+b form. So now it is y= -3x +17
Now plug in
x + 2 (-3x+17) = 49
x + -6x + 34 = 49 (distribute)
-5x = 15 (combine the x terms and subtract 34 on both sides)
x = -3 (divide -5 on both sides to get x alone)
now plug in x into any other equation to get y
x + 2y = 49
-3 + 2y = 49
2y = 52 (add 3 on both sides)
y = 17 (divide 2 on both sides to get y alone)
(-3, 26)

to estimate round the numbers to the closest values
21 can round to 20
118 can round to 120
120*20 = 2400 x 2 = 4800
Answer is A
