Answer:
-2x³ + x² - 3x - 15
Step-by-step explanation:
Simply combine like terms together:
-5x² - 3x - 7 - 2x³ + 6x² - 8
-2x³ + (-5x² + 6x²) - 3x + (-7 - 8)
-2x³ + x² - 3x + (-7 - 8)
-2x³ + x² - 3x - 15
The vertex is 10
Basically, 10 is the lowest value for any given set of values for x
Answer:
9/10
Step-by-step explanation:
To solve this, we simply need to find the common denominator, which in this case, is 10
5 x 2 = 20
1/5 = 2/10
7/10 + 2/10 = 9/10
Thus, our answer is 9/10
Answer:
y = 0.1491x + 0.7556
R² = 0.6943
r^2 at .69 ≅ .7 is somewhat strong
y = 0.1491(15) + 0.7556
