To calculate:
Solve the system by the method of elimination. Label each line with its equation.
Answer to Problem 12E
There are infinite solutions for this pair of equations as they are consistent.
Explanation of Solution
Given information:
The given pair of equations are
Concept used:
These equations can be solved graphically and algebraically. We can use the method of elimination to solve it.
Calculation:
As per the given equations we can see that there are two variables and by adding these two equations we can eliminate one variable.
Before adding we need to multiply second equation with 3 so that we can cancel y variable.
By simplifying these equations we get,
Now let us add both the equations.
From this we can know that these two equations lie on the same line.
Conclusion:
There are infinite solutions for this pair of equations as they are consistent.

If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach.
