Make y the subject in both equations



For the second equation

The two equations are parallel because they have the same gradient or slope but different y intercepts.
This type of equations have no solution because they will never intersect.

The correct answer is C
Answer:
4/6
Step-by-step explanation:
<u>Answer:</u>
$14
<u>Step-by-step explanation:</u>
Assuming the cost of folder to be
, then the cost of notebook will be
and the cost of set of pencils will be
.
Cost of the folder = $2
Cost of notebook = 4 × 2 = $8
Cost of pencil = 2 × 2 = $4
Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14
Since z is the midpoint, rz and zt must be equal
4x - 15 = 25
4x = 40
X = 10
Plug the answer in and rz equals 40-15 which is 25.
25 + 25 = 50
Or if you really wanted, since you know 25 is half, just add them together right off the bat. (25 and 25, I mean)
