Answer:
c. In 2 seconds, the commuter train travels 120 feet.
Step-by-step explanation:
Given
The attached graph
Required
What does x-coordinate of 2 represents
Represent this coordinate with (x,y)
From the graph:
when 
Note that:
x = time and y = distance
So:

Which means:
At 2 seconds, the train has travelled a distance of 120ft
<em>From the list of options, (c) is correct</em>
Distribute the negative b and negative one to he terms in the parentheses
In an expression, if there area brackets, you always have to expand THEN solve it
Answer:
93°, 89°, 93°
Step-by-step explanation:
∠1 and ∠4 are supplementary angles:
m∠1 + m∠4 = 180°; m∠1 = 93°
∠2 and ∠4 are vertical angles:
m∠2 = m∠4 = 87°
∠3 and ∠4 are supplementary angles:
m∠3 + m∠4 = 180°; m∠3 = 93°
Answer:
0
Step-by-step explanation:
Given the points J (1,-10) and K (7, 2)
From the section formula

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is obtained using the formula:

The y-coordinates of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.
Use ratio and proportion
5.25/x= 82/100
cross multiply
82 x= 525
x= 6.4 miles
Hope this helps
