2. Mr. Alvarez if buying tacos for his fellow teachers. The price is $5 for fish tacos and $3.50 for chicken tacos. The total bill for 25 tacos came to $96.50 a. What variables are in the problem
b. Make a system of linear equations based on the information in the problem (hint: are there any rates of change?)
c. Solve the system of linear equations from part b. how many of each taco did Mr. Alvarez buy?

7x+8y=-18, 4x-9y=-3 solve the system of equations

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

To prove that def ~ gfh by the sss similarity theorem using the information provided in the diagram, it would be enough additional information to know that
