Answer:

First choice: 58 seconds.

Step-by-step explanation:

27.8 is approximately 28 seconds, because 8 ≥ 5, so the number rounds up.

30.12 is approximately 30 seconds, since 1 < 5.

So, 28 + 30 is 58. Therefore, 27.8 + 30.12 ≈ 58.

Find the equation of the line shown below...
vovangra [49]

Answer:

y = -1/4x+2

Step-by-step explanation:

We can find the slope by finding two points on the line, and doing (y1-y2) ÷ (x1-x2). The two points I chose were (0,2), and (4,1). We can plug this into the equation to get (2-1) ÷ (0-4), to get -1/4, which is our slope. We can see on the graph, that the line intersects with the y axis when the y coordinate is 2, making the y-int 2.
