Answer:
8/54 or 4/27
Step-by-step explanation:
(8/9)/6 =
8/9 ÷ 6 when divide turn the division sign into multiplication and flip the second fraction ( reciprocal))
8/9*1/6 = 8/54 if simplified =4/27
Answer:
Step-by-step explanation:
The common ratio of a geometric sequence can be found dividing the current term in the sequence by the previous term in the sequence. In other words, where:
is the common ratio of the geometric sequence
is the current term in the sequence
is the previous term in the sequence
- For and
- For and
Since the ratio is the same for both pair of number in the geometric sequence, we can conclude that 5 is the common ratio of the sequence.
<u>Answer:</u>
Option C. The solution for the system of equations is (-1,7) and (-4,13)
<u>Solution:
</u>
The equation for the system given is,
Now we can write,
(//simplifying)
When
When
So, solution is C, (-4,13) and (-1,7)
Answer:
R(-2,0)
S(0,-4)
T(-4,-3)
Step-by-step explanation:
So first you gotta subtract 2 from each x value and 1 from each y value. After you do that, you get:
R(0,2)
S(-4,0)
T(-3,4)
then i put it all onto a graph, and rotated it 90* counterclockwise, from the origin, which puts it in quadrant 3, with the final coordinates above.
The expression is
5x + 5y
We are to prove that it is an odd integer when x and y are integers of opposite parity
First, we can assume
x = 2a (even)
y = 2b + 1(odd)
subsituting
10(a + b) + 5
5 [(2(a + b) + 1]
The term
2(a + b) + 1 is odd and the result of an odd number multiplied by an odd number is odd
