If the value of b is 6 then the system will have an infinite number of solutions since they will be the same lines.
Answer:
option-A
Step-by-step explanation:
For company-1:
d=3m+5
so, the rate of change =3
For company-2:
we can find rate of change
rate of change is
now, we can use point slope form of line
y1=12 , x1=0
We can see that
rate of change of first company(3) is greater than rate of change of second company(1)
It should be noted that a pantograph consists of four rods that are joined together in order to form a parallelogram with the joints varying in relation to the scale of reproduction.
<h3>
Pantograph</h3>
In a pantograph, the mechanical assembly is based on the shape of a parallelogram.
It should be noted that the operation of a pantograph can be related to dilation as it has a fixed center and two points which are a drypoint that follows the contour of the original drawing, as well as a pen point that traces the reproduction in an enlarged or reduced form.
In order to enlarge a drawing, the index is positioned between the fixed center and the pen. Therefore, to reduce it, the pen is set between the fixed center and the index.
Lastly, to copy a drawing on the same scale, it can be deduced that the index and the pen are equidistant from the fixed center.
