Answer:
The best way to show and explain direct proportional relationships is by graphing two sets of related quantities. If the relation is proportional, the graph will form a straight line that passes through the origin.
-8+b2-(5+b2). Since the - is outside the paranthesis the signs inside change: -8+b2-5-b2. -8-5=-3, b2-b2=0. Your answer: -3 :)
Answer:
6574900
Step-by-step explanation:
Answer:
a = 15, b = 7, c = 5, d = 10, e = 12
Step-by-step explanation:
You only need to find d.
22+d=32, d=10
Only one choice has d=10
Don't waste time checking the others.
1. x/9+10=11 (x=89)
2. 3x-5=-2 (x=1)
3. 2x+15=-23 (x=19)
4. 5x-4=16 (x=4)
5. -8x+9=-7 (x=2)
6. 10x-12=-28 (x=1.6)
7. 3x+7=52 (x=15)
8. 5x-11=19 (x=6)
9. 4x+13=-91 (x=-26)
10. 2x-7=43 (x=-19)
