Find the minimum and maximum values of k=-x +3y subject to the constraints. 2x -y> 4 -x+2y< 4 y< 6 x> 0, y> 0
note: the question accompanies a graph too.

The square root of 9x plus 7 plus the square rot of 2x equall to 7

Write an equation of the line that passes through the point (2, 3) and is perpendicular to the line x = -1. a) y = 1 b) y = 3 c) y = 0 eliminate d) y = -3

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.
