Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
Yes, they are. They cannot happen both. Every time that you roll a cube you can get only one number, then if you roll a 4 you cannot roll a 3 at the same tiem, and if you roll a 3 you cannot roll a 4 at the same time.
Mutually exclusive events cannot happen at the same time.
Answer:
not enough information
Step-by-step explanation:
Looks like the two lines meet at (1,-1) so B is the answer.
price of cycle = 3600 Rs
if the price is reduced by 20%, the price will be:
3600 - (20/100*3600) = 3600 - (20*36)
= 3600 - 720
= 2880 Rs
if the price is further reduced by 1/4 (25%),
2880 - (25/100*2880) = 2880 - 720
= 2160 Rs
Therefore, if the price is reduced first by 20% and this is further reduced by 25%, the final price after reduction will be 2160 Rs.
