3x-4(2x-6)+9

And not just answer an explanation too

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x

If on=8x-8,lm=7x+4,nm=x-5,and ol=3y-6

Solve the system of equations. x=-2y+1 and x+2y=9. show work
