Is that supposed to be y=-2x+1?
i cannot solve without the proper equation lol
The answer is D they are proportional equal to negative 4<span />
Add 3.2 to both sides
Simplify -20.7 + 3.2 to -17.5
Multiply both sides by 7
Simplify -17.5 x 7 to -122.5
Switch sides
Answer: y = -122.5.
Answer:

Step-by-step explanation:
The sine function has the general equation
where
- A is the amplitude or vertical stretch
- k is the period factor
- b is the horizontal shift
- h is the vertical stretch
We start with
were A=1 and h=0. We transform the function by multiplying A by 2 for a vertical stretch. A=1(2)=2. A is now 2.
We finish transforming the function by shifting it up 3 units. This means h=0 becomes 0+3=3. H is now 3.
Our new function is
