12. Use the numbers in the box to write the solution to the system of linear equations. Numbers can be used more than once. Write each number in the appropriate box.
9x + y = 30
y = 6x - 15
-3 -1 0
3 4
-6
1
Solution:

The sum of two numbers is 12 and their difference is 18 what are the two numbers

If g^-1(x) is the inverse of g (x) which statement must be true

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
