That's a line:
g(x)=0.5*x-1, pick up some x, and get the y.
For instace: x=0, g(0)=y=-1, x=2, g(2)=y=0.
Two pints are enough for a line.
For this case we have the following expression:
To verify the answer we have:
Multiplying both sides of the equation by -14:
Thus, the answer can be verified with:
Answer:
Answer:
4:6 but if you reduce it is 2:3
Step-by-step explanation:
Answer:
1 gallon of paint will paint 400 ft² of the wall
Unit rate = 400 ft² per gallon
Step-by-step explanation:
From the graph, when 1 gallon of paint was used, (x = 1), an area of 400 ft² of the wall was painted (y = 400).
Unit rate = y/x. That is, the amount of square feet of wall that would be painted using 1 gallon of paint.
Unit rate = 400 ft²/1 gallon = 400 ft²/gallon.
