Answer:
Step-by-step explanation:
1st use the two points to find the slope of the line that passes thru those two points
m = y2 - y1 / x2 - x1
where point1 = ( x1, y1 ) and point2 = (x2, y2 )
your are given P1 = ( -2,10) and P2 = (1,1)
find the slope
m = 1-(-2) / 1-10
m = 1+2 / -9
m = 3 / -9
m = - 1/3
then use the point-slope formula [y-y1 = m(x-x1)] with either of the two points, I'll use P2 b/c it seems easier (1,1) , you get the same results with either point and work the problem to the slope-intercept form [y = mx +b ]
y -y1 = m(x-x1)
y-1 = -1/3(x-1)
y-1 = -1/3x + 1/3
y = -1/3x + 1/3 + 1
y = -1/3x + 4/3
:) got it ?
Answer is A. it’s being scaled by 4, so divide 5 by 4.
Answer:
2.8592933268
Step-by-step explanation:
tan(72) = 8.8/x
=> x = 8.8/tan(72) = 2.859293326849
Answer:
30 minutes to 40 minutes.
Step-by-step explanation:
From the graph attached,
Distance of Sabrina from her home has been given on y-axis and time taken is on x-axis.
Sabrina's walked 2 miles to reach the library in the duration = 30 - 0
= 30 minutes
She stayed at the library from 30 minutes to 40 minutes (Represented by the straight horizontal line).
Then the third segment represents the journey of Sabrina from library to home.
Therefore, Sabrina was at the library between 30 minutes to 40 minutes.
