Answer:
option D is rational
Step-by-step explanation:
A rational number is a number that can be written in the form of fraction or integer
here in the given question
A) 1.5 + √1.5
now,
√1.5 is not rational as √1.5 = 1.2247448713915890490986420373529
hence A is not rational
b) 12 - √12
√12 is not rational as √12 = 3.4641016151377545870548926830117
hence B is not rational
c) 
here,
is not rational
D) 
now,
√25 = 5
hence,
=
= 5
therefore,
option D is rational
Answer:
- there are no solutions (lines do not intersect)
- there is one solution (lines intersect at one point)
- there are an infinite number of solutions (lines overlap—are the same line)
Step-by-step explanation:
"A system of linear equations" covers a lot of territory. In Algebra 1, it usually means two linear equations in two unknowns. Each of those equations will graph as a line on a coordinate plane.
A solution is a point that satisfies all the equations. That is, it is a point that is on all the lines described by the system of equations.
The geometry of lines on a plane comes into play with regard to solutions.
- The lines may be parallel, hence never intersect. (<em>No points</em> will be on all the lines.)
- The lines may intersect at <em>one point</em>.
- The lines may be the same line, overlapping, identical, coincident, consisting of <em>all the same points, an infinite number</em>.
