Can I please get help with this question?
Nimfa-mama [501]

Answer:

-4x + 3 (2x - 5) = 31<br><br> Please help &amp; explain how you got to the answer
denis23 [38]
-4x + 3(2x - 5) = 31          (use distributive property to remove parentheses)
-4x + 6x - 15 = 31            (combine like terms)
2x - 15 = 31                    (add 15 to both sides)
     +15    +15
2x = 46                          (divide both sides by 2)
x = 23

If sin(x) = cos(y) for acute angles x and y, how are the angles related?
Vesnalui [34]

Answer:

b. complementary

Step-by-step explanation:

-Complementary angles are angles that add up to 90°.

-These are usually the two acute angles in the right triangle.

#To verify, lets take the two angles 30° and 60°:

Cos \ 60\textdegree=0.5\\\\Sin \ 30\textdegree=0.5\\\\\therefore Sin \ 30\textdegree=Cos \ 60 \textdegree=0.5

#We can reverse as:

Sin \ 60\textdegree=0.86603\\\\Cos \ 30\textdegree=0.86603\\\\\therefore Sin \ 60\textdegree=Cos \ 30\textdegree=0.86603

Hence, two angles are said to be complimentary if they sum up to 90°.
