The domain x ∈ {-5; 0; 5}
the relation: 2x + y + =1 → y = 1 - 2x
Put the values of x from domain to the equation of the relation:
for x = -5 → y = 1 - 2(-5) = 1 + 10 = 11for x = 0 → y = 1 - 2(0) = 1 - 0 = 1for x = 5 → y = 1 - 2(5) = 1 - 10 = -9
Answer: {-9; 1; 11}

I think it's 9:5 sorry if I'm wrong.
Answer:
4
Step-by-step explanation:
because you do 2-1 and then 3 * 3 the equation would look like this
1 + (3*3) /
1+9/ 3
1 + 3
4
Answer:
After 5 additional days it will be equal
Step-by-step explanation:
1st special: 6x + 50
2nd special: 12x + 20
6x + 50 = 12x + 20
Subtract 20 from both sides;
6x + 30 = 12x
Subtract 6x from both sides;
30 = 6x
Divide both sides by 6;
x = 5
