Answer:

Step-by-step explanation:
Given: sin x + cos x
To change the given trigonometry expression in term of sine only.
Trigonometry identity:-
Expression: 
We get rid of cos x from expression and write as sine form.
Expression:

Hence, The final expression is only sine function.
7x + 15 = 38
7x = 38 - 15
7x = 23
x = 23/7 (twenty- three sevenths)

Answer:
g(x) = -2|x+1| -3
Step-by-step explanation:
f(x) = |x|
y = f(x) + C C < 0 moves it down
y = |x| -3 for shifting down 3
y = f(x + C) C > 0 moves it left
y = |x+1| -3 for move it left 1
y = Cf(x) C > 1 stretches it in the y-direction
y = 2|x+1| -3 to stretch it 2 vertically
y = −f(x) Reflects it about x-axis
y = -2|x+1| -3
1. We will multiply 2 * 27 = 54 and then divide by 3, 54/3 = 18
2. We can multiply across 1/2 * 2/3 = 2/6 = 1/3
3. We can multiply across 2/9 * 3/5 = 6/45 = 2/15
4. We can multiply across and get 6
5. 1 3/4 is equal to 7/4
We can multiply across 7/4 * 5/7 = 35/28
