Answer:
GCF = 5
Step-by-step explanation:
15x² - 10x + 5
x is not contained in all 3 terms thus is not a factor
15 has factors 1, 3, 5, 15
- 10 has factors ± 1, ± 2, ± 5 , ± 10
5 has factors 1, 5
The common factors are 1, 5
Then GCF = 5
Answer:
The answer should be 69°
Step-by-step explanation:
Each line is being cut by a transversal, that means that the degree on the other side of it, added with the given degree will add up to 180°
1. On the right, you need to find the interior angle where 160° is outside so you subtract 180° from 160° to find the angle inside. That gives you 20°
2. On the top left you have 131° so 180°-131°=49°
Next you add the angles you have and then subtract it from 180 to get the interior angle with n° outside.
3. 20°+49°=69°
4. 180°-69°=111°
Then you do the same thing as the beginning which would be n°+111°=180°
5. n°+111°=180°, that means n=69°
Hopefully that clears it up for you :)
Each dive goes further down, so it represents -50 ft (not positive which would represnt going up).
y= -125-50x
We know that there are 3 dives so plug that in for x
y= -125-50(3)
y= -125-150
y= -275
Final answer: -275 ft
