Graph -3x + 9y = -27​
Svetllana [295]

Answer:

Step-by-step explanation:

The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.

-3x + 9y = -27

9y = 3x - 27

y = 1/3x - 3

By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.

suppose the distnace in feet that an object travels t seconds is given by the formula d=64t^2 how far would the object travel af
Darya [45]

Answer:

The object travels 144,000,000 feet.

Step-by-step explanation:

The distance the object travel after t seconds is given by:

d(t) = 64t^2

How far would the object travel after 1.5 * 10^3 seconds

This is d when t = 1.5 \times 10^3 = 1500, so d(1500)

d(1500) = 64*1500^2 = 144000000

The object travels 144,000,000 feet.
