step 1
x-6 = 5(x + 2) equation/Question
step 2
x-6 = 5(x + 2) simplify
x+(-)6=5x+10
x-6=5x+10
step 3
x-6=5x+10 subtract 5x
-4x-6=10
step 4
-4x-6=10 add 6
-4x=16
step 5
answer
x=-4
Answer:

are 
and 
, respectively.
Step-by-step explanation:
The sine function is positive in the first and second quadrants, that is, 
. Then, there are two solutions for the given value by means of the following inverse trigonometrical function:
and
The two solutions for are and , respectively.
This is a picture of the answer.
<span>The correlation
r between the age of a car x , and the cars mileage, y is 0.768. this means
that 76.8 % of the variation in mileage can be explained by the differences in
the cars ages, 100 – 76.8 = 23.2% of the variation cannot be explained</span>
