Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle
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:
(-7, 8)
step-by-step explanation:
- original coordinates of B: (-9, -8)
if translated two units horizontally, there will be change in x axis
- new coordinates: (-9+2, -8) → (-7,-8)
if reflected over x-axis, use the formula: (x,y) → (x, -y)
- new coordinates: (-7, -(-8)) → (-7, 8)
