5× the first equation + the second equation will give an equation of 'a' to its value.
The correct option regarding the system of equations is given as follows:
B. The solution is nonviable because the time cannot be negative.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The systems use linear equations, and the solution is the intersection of the lines. In this problem, the curves intersect at (-4,0), that is, they have the same percentage at a time of -4 seconds, which is nonviable, as the time cannot be negative, hence option B is correct.

Given:
The base is a rectangle of dimension 7 cm×6 cm.
The length of each diagonal side = 10 cm
To find the height of MT.
Formula
By Pythagoras theorem we get,
where, h be the hypotenuse
b be the base and
l be the height.
Now, in this diagram,
The perpendicular distance of M from BC = 3 cm
Slant height = 10 cm
Taking, b = 3 and h = 10 we get,
or,
or,
or,
Hence,
The height of MT is 9.5 cm.
