The grid shows figure Q and its image figure Q' after a transformation: Figure Q is a pentagon drawn on a 4 quadrant grid with v

kumpel [21]

Check the picture.

we notice that for every pair (x, y) in Q, there is a point (-y, x) in Q',

this means that the transformation is a 90° counterclockwise rotation around the origin.

The transformation can be also noticed by sight in the figure.

Answer: 90° counterclockwise rotation

Solve the equation<br> 9x² – 29x – 28 = 0<br> Give your answers to 2 decimal places when appropriate

andrew-mc [135]

Answer:

x = 4 or x = 0.78

Step-by-step explanation:

9x² – 29x – 28 = 0

2 roots: x = ((-(-29) ± √(-29)² - 4 x 9 x (-28)) / (2 x 9)

= (29 ± √841 + 1008) / 18

= (29 ± 43) /18

x = 72 /18 = 4 or

x = -14 /18 = - 0.78
