Where to Dig: The dinosaur's
hip and legs are at another
point on the grid - the
solution to the system of
equations below. This time, use
the substitution method to find
the fossil!
x = 43
-5x + y = -210

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
