Answer:
1. 2
2. -9
3. 2+-9
4. -7
5. -15 + 8 = -7
Step-by-step explanation:
The surface of the water is 0. If Paula is above the surface of the water than she is positive. If she is below or heading down she is negative. She starts 2 feet above which is 2. She descends a total of -9 from 2 to -7. She ends up -7 or 7 feet below surface. So she travels from 2+-9 = -7.
Yolanda owes her friend $15 or -15. She earns $8 a week or +8. If she earns 8 dollars this week and pays Yolanda back then -15+8=-7. She now owes $7.
Answer:

4/10= ?/15
cross multiply 4 and 15 = 60
60/10 = 6
He won 6 races

Answer:
x=-1
Step-by-step explanation:
-15 = 22x + 7
-7 -7
----------------------
-22+22x
x=-1
Answer:
x < 7.5
Step-by-step explanation:
Divide by 2 on both sides to find x
2x/2 < 15/2
x <15/2
x<7.5
<span>1) The two functions are straight lines. 2) The two functions have the same y-intercept, i.e. y=1. then both graphs cross each other at (0,1), 3) the graph of y = 2x + 1 has slope 2, while graph of y = 1/2 x + 1 has slope 1/2, then both are growing functions, but the former is steeper, this is its rate of change is greater than the rate of change of the second. </span>
