Answer:
$4.5
Step-by-step explanation:
Hot dogs=h
Cheese burgers=c
2h+3c=20
2h+5c=29
There are two ways to solve-
1. Elimination- multiply the bottom by -1.
2h+3c=20
-2h-5c=-29
-2c=-9
c=4.5
2. Just move 2h, and you get 2c=9, 4.5
Answer:
The standard form of the equation for this line can be:
l: 2x + 5y = -15.
Step-by-step explanation:
Start by finding the slope of this line.
For a line that goes through the two points
and
,
.
For this line,
.
Find the slope-point form of this line's equation using
, and- The point
(using the point
should also work.)
The slope-point form of the equation of a line
- with slope
and - point
should be
.
For this line,
The equation in slope-point form will be
.
The standard form of the equation of a line in a cartesian plane is
where
,
, and
are integers.
.
Multiply both sides of the slope-point form equation of this line by
:
.
Add
to both sides of the equation:
.
Therefore, the equation of this line in standard form is
.
Answer:
4
Step-by-step explanation:
The cardinality of a set is the number of members in the set. So besides the numbers in between the 18 and 58 you currently have 4.
