That's a little messy :)
If that is: -1/[3^(n-1)]
-1, -1/3, -1/9, -1/27, -1/81
If you follow the steps of PEMDAS it should be Multiply by 3,subtract 2.
<span>The general formula for sine function is y(x) = A sin(2πx/t). Here, x = displacement = 4 , time period , t = 10 and Amplitude, A = 0.75, then, y(4) = 0.75 sin( 2π*4/10) = 0.75*0.04 =0.03. Thus, the value of y(4) wll be 0.03</span>
Answer:
The answer is 15x+10b-45y+50 which is the choices C.
Step-by-step explanation:
5(3x+2b-9y+10)
15x+10b-45y+50
