Answer:
5X + 8Y >= 300; intersection at (-20, 50)
Step-by-step explanation:
let t = work hours
0 < t < 30
X = time lawn mowing
Y = time babysitting.
X + Y < 30
5X + 8Y >= 300
We could solve...
X < 30 - Y
5(30 - Y) + 8Y >=300
150 - 5Y + 8Y >= 300
3Y >=150
Y >=50
then X < -20
intersection at (-20, 50)
Answer: 
Step-by-step explanation:
given data:
T = 58 degree Celsius.
changes in temperature = 3dregres every hour = 4.
solution:
substitute the value for h into the equation.
the set with 
best represents the function range.
4 because 2cups of 1/2 cups=1cup
2x2=4
