Given:
Line a is perpendicular to line b
.
Line a passes through the points (1,-8) and (9,-12)
.
Line b passes through the point (-8, -16).
To find:
The equation of b.
Solution:
Line a passes through the points (1,-8) and (9,-12)
. So, slope of line a is
Product of slopes of two perpendicular lines is -1.
Slope of line b is 2.
If a line passing through a point 
with slope m, then equation of line is
Line b passing through (-8,-16) with slope 2. So, equation of line b is
Subtract 16 from both sides.
Therefore, the equation of line b is .
Given that loan amount P=20000
Interest rate r=5% = 0.05
Time of loan t=4 years
Now to find the interest amount we just plug those values into formula
simple interest = P × r × t
simple interest = 20000* 0.05* 4
simple interest = 1000 * 4
simple interest = 4000
Hence final answer is choice b. $4000.
Answer:
45
Step-by-step explanation:
200 divided by 2 = 100-55=45
Answer:
The correct answer is option B.
Step-by-step explanation:
Two point form of the equation:
