Answer:
y = 6
Step-by-step explanation:
-4x - 9y = -26
substitute -7 for x
-4 (-7) - 9y = -26
28 - 9y = -26
-28 -28
-9y = -54
/-9 /-9
y = 6
hope this helps :)
17) 1800, 900, 450, 225,
Your answer
The third missing term in the series 1800, 900, 450, 225 is 112.5, since each term in the series is half of the previous term.
The third missing term in the series 1800, 900, 450, 225 is 112.5. It appears that each term in this series is half the size of the previous term. So if you are looking to increase through the series:
So the next term should be 112.5.

Answer:
, , and
Step-by-step explanation:
1.
Let's find a common denominator:
=
2/(x-1)x(x+1)
2.
Distribute exponents:
2^3(y^2)^3
__________
8^2(y)^2
Numerator:
2 to the power of 3 equals (2 · 2 · 2) = 8
y to the power of 2 to the power of 3 equals, y to the power of 6 (this is because when exponents in parenthesis are held to the power of another number outside of the parenthesis, you multiply them)
Now let's simplify the denominator:
8 to the power of 2 equals (8 · 8) = 64
y to the power of 2 is just y to the power of 2, so our new expression is:
Let's cancel the terms further:
8/64 can be simplified to 1/8
And when you cancel exponents, you subtract the denominator's exponent from the numerator's exponent ( = )
Now put them together:
Which is,
=
y^4/8
3.
The common denominator for both fractions is 3t, so let's make -1/3's denominator 3t by multiplying t to both the numerator and the denominator:
-1 · t
_____ = -1(t)/3t = -t/3t
3 · t
Now let's solve for the numerator:
(t + 2) - t, the t's cancel out, t - t + 2 = 2
And the denominator stays the same, so it will still equal 3t
Finally, you'll get an answer of
=
2/3^2
Answer:
-8.25
Step-by-step explanation:
-16.5/2
Answer: Joey's answer should be a square.
Step-by-step explanation: Given that Joey is asked to name a quadrilateral which is also a rhombus. We are to find Joey's answer.
Rhombus : a quadrilateral having all the four sides equal and diagonals bisect each other perpendicularly.
We know that the only quadrilateral having four equal sides and diagonals bisecting each other perpendicularly is a SQUARE.
Also, a square has all angles as right-angles in addition.
Therefore, Joey's answer should be a square.
