Step-by-step explanation:
15 = |x| - 5
|x| - 5 = 15
|x| = 15 + 5
|x| = 20
x = ±20
x = -20 or 20
Option → B
Okay, what are you asking?

Step-by-step explanation:
A. We must consider that Marisa is walking a straight trail
so that the time required to cover a distance is persistent or constant.
B. The slope of the line is: y = m x + b
Where in this problem, y is the distance, m is the slope or
the time it takes for each block, x is the time, and b would be the y intercept
or the initial location of Marisa.
C. The slope m can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (8 – 12) / (6 – 0)
m = -0.67
The negative sign is the space between Marisa and Sanjay’s
home is declining by time. It further means that there is a cut in 0.67 blocks
per minute.
D. y = - 0.67 x + b
The starting point of Marisa is at 12 blocks away from
Sanjay’s home, therefore let b be 12.
Finding for time when distance is y = 0:
0 = -0.67 x + 12
x = 17.9 minutes
Therefore it takes approximately 17.9 minutes to go to Sanjay’s
home.
