You move left 4 units. You end at (-5, -5). Where did you start?
Triss [41]

Answer:

(-1,-5)

Step-by-step explanation:

To understand where this point was before the transformation you must first understand the transformation itself. Shifting left is a horizontal translation, this means that it will affect the x-coordinate. The x-coordinate is the first digit in the pair. Therefore, in the case of (3,5), 3 would be the x-coordinate. Additionally, moving left is moving towards the negative, so it is the same as subtracting. Thus, to find where you started, work backward. Do this by adding 4 to the x-coordinate. This means the beginning coordinate was (-1,-5).

Please help i’m doing trying to do my gf work please i’ll give you brainliest
otez555 [7]

Answer:

t = 5 seconds h = 128 feet

Step-by-step explanation:

The given equation of the object is :

h(t)=-16t^2+64t+80 .....1

When it hits the ground,

h(t) = 0

So,

-16t^2+64t+80=0\\\\t=-1\ s\ and\ t=5\ s

The object will hit the ground in 5 seconds.

Now, put t = 1 s in equation (1).

h(1)=-16(1)^2+64(1)+80\\\\h(t)=128\ ft

The object is at a height of 128 ft at 1 second.
