Answer:
y=2x-4
Step-by-step explanation:
If a line is parallel to another line, the only thing that's different in the equation is the y-intercept. Therefore we can solve for the y-intercept using the point (4,4)...
Note that the slope-intercept equation is y=mx+b where b is the y-intercept and m is the slope. x and y are the x and y coordinate pairs.
y=2x+b
4=2(4)+b
4=8+b
b=-4
Therefore the equation of the line that is parallel to y=2x+4 and passes through (4,4) is...
y=2x-4

Answer:
Step-by-step explanation:
the first graph has points (-1, -1) and (2, -2)
slope m = (y2-y1) / (x2-x1) = (-1+2)/ (-1-2) = 1/-3 = -1/3
the second graph has points (0, -3) and (2, 0)
slope m = (y2-y1) / (x2-x1) = (-3-0)/ (0-2) = -3/-2 = 3/2
for the table
x. y
-3. 4
0. 1
slope m = dierence in y /diference in x = 4-1 / -3-0 = 3/-3= -1
Answer:
B. 8.66%
Step-by-step explanation:
In this case we have to evaluate the following formula:
n = e ^ (k * t)
where n would be the growth rate, we are told that it doubles therefore it is 2.
k is the monthly rate and time, 8 months.
Solved for k, we are left with:
ln (n) = k * t
k = ln (n) / t
replacing we have:
k = ln (2) / t = 0.693 / 8
k = 0.0866
If we take this to a percentage it would be 0.0866 * 100 = 8.66%
Therefore the answer is B.
