Answer:
Im not sure if this is what your looking for but
Step-by-step explanation:
(-2)(-18)=36
or
(x)(y)=36
But the first one should be right.
Standard form is ax+by=c
mnus 7y both sides
6x-7y=0
Answer: A = 4 P = π PS = -π/2
<u>Step-by-step explanation:</u>
y = A sin(Bx - C) + D where
- A is the amplitude
- Period = 2π/B
- Phase Shift = C/B
- D is the vertical shift
Given: y = -4 sin(2x + π) - 3
- A (amplitude) = 4 <em>the negative sign is a reflection, not amplitude</em>
- B = 2
- C = -π
- D = -3
Amplitude = 4
