Step-by-step explanation:
4.35 / 5 = 0.87
0.87 x 11 = 9.57
Answer:
<h2>x² - 14x - 15 = (x − 7)² − 64</h2><h2>Then the coordinates of the vertex are (7 , -64)</h2>
Step-by-step explanation:
x² - 14x - 15 = x² - 14x + (49 - 49) - 15
= (x² - 14x + 49) - 49 - 15
= (x² - 14x + 7²) - 49 - 15
= (x − 7)² − (49 + 15)
= (x − 7)² − 64
x² - 14x - 15 = (x − 7)² − 64
Then the coordinates of the vertex are (7 , -64)
