Answer: the slope is -1/15 and it means that the distance from home decreases 1/15 units per minute of walk, which indicates the your are going home.
Explanation:
The equation d = 4 - (1/5)t has these features:
d = 0 = 4 - (1/15)t ⇒ t = 4×15 = 60 min.
The given equation, d = 4 - (1/5)t is a linear equation, whose y-intercept form is y = mx + b.
The domain of the function is the interval [0, 60], meaning that those are the minutes of the walk.
The range of the function is the interval [4, 0] meaning that the distance goes from 4 to 0 units.
You have plenty information to do the graph:
You can see the graph in the image attached.
The answer to the above question can be determined as -
Let the point on the left side of P be Q, thus coordinates of Q are (a,1) and point on the right side of P be R, thus coordinates of R will be, (a+4, 1).
Now, it given that, between x coordinates of Q and R is 4, and it can be seen that they are getting divided into half.
So, the x coordinate of P will be - a + i.e. a + 2
<u>Thus, the x coordinate of P will be a +2.</u>
Answer:
y = − (7 /2) x + 60 equation could represent the line of best fit for the temperatures, in degrees Fahrenheit, based on the altitudes, in thousands of feet
Step-by-step explanation:
Given:
A plot for temperature and altitude
(Refer the attachment) .......FOR GRAPH
To Find:
Correct relationship between them
Solution:
By using given relationship as we can conclude.
1)y=-5x+70:
Put y=0 then
5x=70
x=70/5
x=14
This value dont corresponds when y=0 in graph
2) y=-10x+70
put y=0 then
10x=70
x=7
This value dont corresponds when y=0 in graph very less than original value.
3)y=-(7/2)x+60
put y=0 then
(7/2)x=60
7x=120
x=120/7
x=17.14
This value corresponds when y=0 in graph
4)y=-(9/2)x+60
Put y=0 then
(9/2)x=60
9x=120
x=120/9
x=13.33
This value dont corresponds when y=0 in graph which much less than original value.
