How do i find the numerical value if x=9 and y=4 of he equation 3(x+8y)

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

Simplify each expression. use positive exponents. show work . (x –2 y –4 x 3 ) –2

Solve the equation for y. -1 = 1/3y + 11. will give 5 stars if answered correctly!
