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!!<br><br>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.

What is the equation of the asymptote? f (x) = 3^x-5+1<br> y=?
Natasha_Volkova [10]

The equation of the asymptote is y=1

Explanation:

The given equation is f(x)=3^{x-5}+1

We need to determine the horizontal asymptote of the equation.

The given equation is of the exponential function of the form f(x)=c \cdot n^{a x+b}+k and has a horizontal asymptote y=k

Hence, from the above equation, the value of k is 1.

Therefore, we have,

k=1

Thus, the horizontal asymptote is y=1

Therefore, the asymptote of the equation is y=1
