72 months=6 years
6×12=72
14 months 0% so evelyn be charged interest after 14 months
72-14=58 months evelyn be charged interest?
Since there are 26 students in Mr. Carson's class, and each kid gets 3 pencils, that means we will multiply 26 and 3, in which we get 78. Now, since boxes of pencils only contain a dozen, which is 12 pencils, we will divide 78 by twelve, in which we get 6.5 boxes. You can't buy half a box, so he will need 7 boxes, since having 6 boxes means that you don't have enough pencils.
Hope this helps!

Explanation:
Write the standard form of the line that goes through
(
3
,
1
)
and is perpendicular to
y
=
−
2
3
x
+
4
.
The equation
y
=
−
2
3
x
+
4
is in slope intercept form
y
=
m
x
+
b
where
m
= slope and
b
= the
y
intercept.
The slope of this line is then
m
=
−
2
3
A perpendicular slope is the opposite sign reciprocal. So, we change the sign of
−
2
3
and switch the numerator and denominator.
Perpendicular slope
m
=
3

To find the equation of the new line, use the point slope equation
y
−
y

=
m
(
x
−
x

)
where
m
=
slope and
(
x
1
,
y

)
is a point.
The slope is
3

and the point is the given point
(

)
.

I think the answer is 2/3 +3 but I’m not entirely sure
X+y=-4
2x-y=1
—————
3x=-3
X=-1
Now replace x in one of the equations to find y
Y=2(-1)-1= -3
Final answer =
X= -1
Y= -3
