Kiersten wants to eat more fruit, so she buys apples and bananas at the farmers' market. She bought 14 pieces of fruit and paid $3.21. If x represents the number of apples and y represents the number of bananas, which system of equations best represents the kinds of fruit and the cost of the fruit Kiersten bought? A)x+y=14
24x+19y=321
B)x+y=14
24a+19y=3.21
C)x+y=321
24x+19y=14
D)x+y=3.21
.24x+.19y=14

Line cd passes through points c(1, 3) and d(4, –3). if the equation of the line is written in slope-intercept form, y = mx + b, what is the value of b? –5 –2 1 5

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
