x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

The sequence which follows the rule that " each number in the sequence is three times as big as the previous number" is 9, 27, 81.
What is sequence?A sequence is an arrangement of any objects or a set of numbers in a particular order followed by some rule.
According to the given question.
We have some sequences
A. 36, 18, 9
Here, the first term of the given sequence is 36 and the second term is 18.
Which means the succesive term of the given sequence is half to the previous term i.e.
\(a_{n} = \frac{a_{n-1} }{2}\)
B. 9, 27, 81
Here, the first term of the given sequence is 9. And the second term of the sequence is 27.
Which means that "each number in the given sequence is three times as big as previous number" i.e.
\(a_{n} = 3a_{n-1}\)
C. 81, 27, 9
Here, the first term is 81 and the second term is 21. Which means that the previous term is 3 times to the sucessive term i.e.
\(a_{n} = \frac{a_{n-1} }{3}\)
D. 9, 18, 36
Here, the first term of the given sequence is 9 and the second term of the sequence is 18
Which means the succesive term of the given sequence is twice to the previous term i.e
\(a_{n} = 2a_{n-1}\)
Hence, the sequence which follows the rule that " each number in the sequence is three times as big as the previous number" is 9, 27, 81.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

The third angle measures 70°
It is an acute triangle.
i know that because eat triangle is 180°, so
if we subtract 40° and 70° from 180°, we get
70°, meaning the three angles in the
triangle are 40°, 70°, and 70°. Because all of

34/9 as a mixed number
Answers
\(\dfrac{34}{9}\) as mixed number
Divide numerator by denominator:
\(34\div9=3R7\)
The 3 becomes a whole number and the remainder becomes the new numerator and the denominator stays the same.
\(\fbox{3$\dfrac{7}{9} $}\)
The mixed number representation of fraction 34/9 is \(3\frac{7}{9}\).
To express the fraction 34/9 as a mixed number.
we need to find the whole number part and the fractional part.
Divide the numerator (34) by the denominator (9):
34 ÷ 9
= 3 remainder 7
The quotient 3 represents the whole number part, and the remainder 7 represents the fractional part.
Therefore, the mixed number representation of 34/9 is \(3\frac{7}{9}\).
