Answer:
in its simplest form a domain is all the values that can go into a function and the range is all the values that come out
Basically they want you to move the variables around so that it matches the standard form which is Ax+By=C.A,B,and C are just coefficients/constants.
so the original equation is
y=x-4
Minus x from both sides to move x to the left hand side.
-x+y=-4
so thats the final answer
-4x + 7 = 11
First, subtract 7 from both sides. / Your problem should look like:
Second, subtract 11 - 7. / Your problem should look like:
Third, divide both sides by -4. / Your problem should look like:
Fourth, change the fraction to a negative. / Your problem should look like:
Fifth, cancel 4 out. / Your problem should look like:

Answer:
x = -1
