Tina wrote the equations 3 x minus y = 9 and 4 x + y = 5. What can Tina conclude about the solution to this system of equations? A. (–3, 2) is a solution to the system of linear equations. B.(–2, 3) is a solution to the system of linear equations. C. (2, –3) is a solution to the system of linear equations. D. (3, –2) is a solution to the system of linear equations.

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
