Answer:
A. -2
B. -10
Step-by-step explanation:
The slope of a perpendicular line will be the negative reciprocal of the slope of the given line:
-1/(1/2) = -2 . . . . slope of the perpendicular line
__
The y-intercept will let the given point satisfy the equation ...
y = -2x +b
2 = -2(-6) +b
-10 = b . . . . . . . subtract 12. This is the y-intercept.
_____
The graph shows the two lines and the points they go through.
Answer:
Intersecting but not perpendicular
Step-by-step explanation:
Assuming you forgot to add the = between y+5 and 2(1)
Since there is a opposite single variable in either equation the lines will intersect but not be perpendicular
Answer:
here is how you do it
Step-by-step explanation:
first you must solve 1% of 20 which is .2
then you solve for 10% which is 2
then you double it which is 4
so you would take 4 dollars of the original price
the cost is $16
