Please answer all four

1. Vertical shift down by 10 units

2. Horizontal shift right by 4 units; reflect over x-axis

3. Vertical compression by a factor of 1/3; vertical shift up by 6 units

4. Vertical stretch by a factor of 2; horizontal shift left by 3 units; vertical shift down by 9 units

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
