it represents that the angle forms at the vertex E
Answer:
30,000 is your answer for ur math problem
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:
Simplify —————
b - a
1.1 Rewrite (b-a) as (-1) • (a-b)
Canceling Out :
1.2 Cancel out (a-b) which now appears on both sides of the fraction line.
Final result :
-1
