Answer: spencer left after 14 days
Step-by-step explanation:
Answer:
B choice.
Step-by-step explanation:
The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.
It is very obvious to tell because of steepness. Low steepness = low value
High steepness = high value.
We can also find the slope by using rise/run.

The change of y over the change of x.
Given the coordinate points (0,1) and (4,0). Both points are part of the graph.


Therefore the value of m is - 1/4
We can use 3 facts:



So, to find our x and our y we can do:
So, now that we know our x and our y we can find our r.

You'll notice, though, that there were two solutions for
, which means we have a positive and a negative for our x. So:

Answer:
<u>-12</u>
Step-by-step explanation:
12 - 15 = -3
4 ( -3 )
= -12
Step-by-step explanation:
35. 1000 m / 1 km = 10³
Move the decimal point 3 places to the right.
36. 100 cm / 1 m = 10²
Move the decimal point 2 places to the right.
37. 1 mm / 1000 μm = 10⁻³
Move the decimal point 3 places to the left.
38. 1 km / 1000 m × 1 m / 100 cm = 10⁻⁵
Move the decimal point 5 places to the left.
39. 1 Mm / 10⁶ m × 1 m / 10⁶ μm = 10⁻¹²
Move the decimal point 12 places to the left.
40. 100 cm / m × 1000 m / km = 10⁵
Move the decimal point 5 places to the right.
