Answer:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Step-by-step explanation:
Isolate the y variables in both equations
Equation 1:
y - 7x = 6
y = 7x + 6
Equation 2:
y + 7x = 8
y = -7x + 8
So, the equations in slope intercept form are:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Answer: hey check out the image
Step-by-step explanation:
<h2>m=(2xw)-6</h2>
Step-by-step explanation:
Let the number of women in the committee be .
Let the number of men in the committee be .
Since it is given that the number of men are 6 less than twice the number of women,
Twice the number of women is
Twice the number less six is
Since it is given that the committee has a total of 45 members,
the total number of men and women is 45.
So,
using (i) and (ii),
Answer: The radius is
r
=
3
.
Explanation:
If the point

−
r

=
0
then its coordinates must verify that equation. That is, if we substitute in the equation of the circle
x
by
−
3
and
y
by
2
we must obtain a true equality. Then, it is enough to clear
r
of that equation:

then:
r
=

.
(Remember
r
is a distance, then it's always a positive number).
