Answer:
The approximate cost during the year 1987 was $7,533
Step-by-step explanation:
The complete question in the attached figure
we have
y -----> is the cost in dollars
x -----> is the year
Looking at the graph we have the points
(1983,5,047) and (1991, 10,019)
To determine the cost in the year 1987, find out the midpoint between the two given points
The formula to calculate the midpoint between two points is equal to

substitute the values


therefore
The approximate cost during the year 1987 was $7,533
Answer:
Option C) y + 4 = x
Step-by-step explanation:
We are given the following information in the question:
Line AB goes through the points A (0, –4) and B (6, 2).
We can use the two-point form of equation of straight line.
The equation of line is given by:
where,
is the point through which the line passes.
The equation of line is:
Thus, the equation of line AB is given by Option C) y + 4 = x
Answer:
80%
Step-by-step explanation:
50 x 50 would be 100 and 50kg=100% and 10 x 2 = 20 so you used 20% therefore you have 80% left.
