Answer:
Step-by-step explanation:
2x - 3 is a linear expression. y = 2x - 3 is the equation describing y.
If x = 1, y = 2(1) - 3 = -1
If x = 2, y = 2(2) - 3 = 1
and so on.
Isn't there more to this problem that merely "2x - 3"?
Answer:
x = 4
Step-by-step explanation:
WX = WY
9x - 11 = 7x - 3..........Then subtract 7x to the other side such that
2x - 11 = -3..........Then add 11 to both sides such that
2x = 8...........Then divide 2 such that
x = 4
Answer:
(x + 5)²
Step-by-step explanation:
Given
x² + 10x
To complete the square
add ( half the coefficient of the x- term )² to x² + 10x
x² + 2(5)x + 25
Then
x² + 10x + 25 = (x + 5)²
<span>3(a+(6x)y) was clearly multiplied out as seen by the 3a and 18xy, so the distributive property was used there. In addition, the commutative and associative properties state that you can rearrange sums, so those were used too </span><span />
Let
be the common ratio between terms. Then
Now denote the
th partial sum of the series by
Multiply both sides by
, then subtract from the above to get
As
, you're left with
