Solve each system by the equation: 1.-x-5y=-19
y=-6x-2

2.3x+7y=24
y=6

3.-x-6y=-2
y=4x+17

4.-5x+y=-2
-4x+6y=-12

5.2x+y=8
4x-y=-8

6.-6x+4y=2
x+y=-7

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.
