BEGGING PLEASEE HELP Parent function of a quadratic equation is y = x²

Which equation shows a transformation of a reflection across the x-axis, a vertical stretch of 3, a horizontal shift to the left by 4, and a vertical shift up by 7

y =-3 (x - 4)² - 7
y =-3 (x - 4)² - 7

y = -3(x + 4)² +7
y = -3(x + 4)² +7

y = 3(x + 4)² + 7
y = 3(x + 4)² + 7

y = -3(x - 4)² +7

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
