Answer:

Step-by-step explanation:

-5x-y=5 since its substitution, take the equation that has the variables on

x=7y-1 opposite sides(x-7y-1) and sub in whats on the opposite side of the

-5(7y -1)-y=5 equal sign (7y-1) in for the x variable in the first equation

-35y+5-y=5. then you distribute the -5 to every value in the parenthesis

-36y=0 then you isolate the remaining variable on one side

y=0 then divide until the variable has no coefficiant

-5x-0=5 then you plug that value back in to the first equation

-5x=5 isolate the variable again

x=-1 then divide again. your y value is 0 and your x value is -1

Plz help me!! Identify the domain and range of each function

Travka [436]

Answer:

Does this help I hope it does :D

How to find the domain and range of a function?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
