x = 50
Answer:
it's 6
Step-by-step explanation:
2*3 is 6 and I*I is i^2 which equals to 1 so overall 6
-7x + 6 =27
subtract 6 from both sides
-7x =21
divide both sides by -7
x= -3
Answer:
-2pi/3
Step-by-step explanation:
y = 2 cos 3(x + 2π∕3) +1
y = A sin(B(x + C)) + D
amplitude is A
period is 2π/B
phase shift is C (positive is to the left)
vertical shift is D
We have a shift to the left of 2 pi /3
