Step-by-step explanation:
2x +8y = 54
x + 9y = 67
x = 67 - 9y
2(67-9y) + 8y = 54
434 - 18y + 8y = 54
434 - 10y = 54
10y = 54 - 434
10y = -380
y = -38
Answer:
f(2.5)=30

Answer:
Step-by-step explanation:
A proportional relationship has equation:
where k is the constant of proportionality.
Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.
We substitute k=-10 into the equation to get:
Therefore the correct choice is
