Yes it is linear, you go up my fours in the y side and go down by two on the x side. The equation is y=2x+19
Answer:
x = -3; substitute it to the other equation.
2(-3) - 7y = 30
-6 - 7y = 30
-7y = 30 + 6
-7y = 36
y = -36/7
we will not round the number because the question is asking for an improper fraction at its simplest form.
Answer:
1.4 hrs or 84 minutes
Step-by-step explanation:
