It's helpful to choose letters to represent the measures of these complementary angles.  Let x represent one and y the other.

What does "complementary angle" mean?  x + y = ??

Let x be the smaller angle.  First, we take "half the measure of the larger angle," or (y/2).  Then we subtract 6 degrees from this result (y/2).  The result is the xmaller angle, x.

Now you have two equations in x and y.  Solve for one of these angles, and then find the other.  Please show your work.

f(x) = (x -  \dfrac{2}{9} )(x +  \dfrac{1}{2} )

\text {When } f(x) = 0 :

(x -  \dfrac{2}{9} )(x +  \dfrac{1}{2} ) = 0

(x -  \dfrac{2}{9} ) = 0  \text { or }  (x +  \dfrac{1}{2} ) = 0

x =  \dfrac{2}{9}  \text { or } x =  -\dfrac{1}{2}

I need help please quiz
Anon25 [30]

Answer:

f(x - 4) = x^2 - 6x+ 8

Step-by-step explanation:

Given

f(x) = x^2 + 2x

Required

Find f(x - 4)

Substitute x - 4 for x

f(x - 4) = (x- 4)^2 + 2(x - 4)

Expand

f(x - 4) = x^2 - 8x + 16 + 2x - 8

Collect like terms

f(x - 4) = x^2 - 8x + 2x+ 16  - 8

f(x - 4) = x^2 - 6x+ 8

Mary, Chau, and David have a total of $87 i their wallets. Marry has 9$ more than Chau. David has two times what Mary has. How m
Pavel [41]

Answer:

Mary = 24

Chau = 15

David = 48

Step-by-step explanation:

The formula is

Mary + Chau + David = 87

And we know that

Chau = Mary - 9

David = Mary * 2

So when we fill this in

Mary + Mary - 9 + Mary * 2 = 87

4Mary - 9 = 87

4Mary = 96

Mary = 24

Chau = Mary - 9 = 15

David = Mary * 2 = 48
