Gary is baking pretzels for his sister's party. some pretzels will be regular and some pretzels will be whole grain. let x represent the number of dozens of regular pretzels. let y represent the number of dozens of whole grain pretzels. gary needs to bake at least 14 dozen pretzels in all. gary has 20 cups of flour. he needs 2 cups of flour for each batch of 12 whole grain pretzels, and 1 cup of flour for each batch of 12 regular pretzels. select the constraints that correctly model the inequality. x≤0 x≥0 y≤0 y≥0 x+2y≤20 x+2y≥20 x+y≥14

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

Can someone me out here number 4 plz

Plot the intercepts to graph the equation
