Answer:
A. Y = -6X + 9
Step-by-step explanation:
Solving for y, we can find the slope of the given line. It is the coefficient of x, 1/6.
-12y = -2x -1
y = 1/6x +1/12
The perpendicular line will have a slope that is the negative reciprocal of this:
m = -1/(1/6) = -6
The y-intercept will be the y-value corresponding to x=0. That value is b=9, given to us by the point the line is to go through. So, we have the slope-intercept form ...
y = mx + b
y = -6x + 9
Answer:
y=-11
Step-by-step explanation:
Answer: The director can choose two singers from the 20 singers in 190 different ways.
Step-by-step explanation:
Given : The total number pf singers auditioning for the musical= 20
The number of singers looking director for = 2
We use combinations here because order of selecting singers does not matter.
(If order matters then we use permutations.)
The number of combinations of to select r things of n things =
So the number of ways can the director choose two singers from the 20 singers=
Therefore , the director can choose two singers from the 20 singers in 190 different ways.
