Answer:
Sally ends at 3 feet below zero point.
Step-by-step explanation:
Let be
the height with respect to zero point, which is represented by the following sum:

Where:
- i-th travelled height, measured in feet.
In addition, positive sign means ascension, whereas negative sign means descent.
The statement can be translated into the following mathematical identity:



Sally ends at 3 feet below zero point.
9the equation of a line in ' slope- intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
y = 3x + 1 is in this form
with slope = 3 and y-intercept = 1
the graph crosses the y- axis at ( 0, 1 )
from this point moving 3 units vertically up and 1 unit horizontally right gives the point (1, 4 ) . Repeating this gives the point (2, 7 )
Plot the points (0, 1 ), (1, 4 ) and (2, 7 )
Draw a straight line through them for graph of y = 3x + 1
Answer:
$491.25 and 0.15xx + 300
Step-by-step explanation:
15%=0.15
$1275×0.15=$191.25 in sales
$191.25+$300=$491.25
He would make $491.25 a week in which he made 1275 in sales.
0.15xx + 300 = total earnings
He would make 0.15xx + 300 if he made xx dollars in sales
