X+ y = 8
y = x - 2
i'm not really sure what to do here but it says i can use substitution or elimination method.

Evaluate-27 ^4/3/8 a) - 81/16 b) 81/16 c) 16/81

For what value of (y) is 3^3/3^y =1/9

Match each whole number with a rational, exponential expression 3 square root 27^2find the domain and range of the exponential function h(x)=125^x. explain your findings. as x decreases does h increase or decrease? explain. as x increases does h increase or decrease? explain.
