Barry’s mountain bike weighs 6 pounds more than andy’s.

if their bikes weigh 42 pounds altogether, how much does barry’s bike weigh?

if we let a represent the weight in pounds of andys bike then a+6 will represent the weight in pounds of barry's bike

a+(a+6)=42

solve for a.

(a.) 18

(b.) 24

(c.) 6

(d.) 40

The ratio of two numbers is 5 to 4. the sum of the numbers is 99. what number is the greater of the two numbers?

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

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?
