In golf, scores that are under the expected score are represented
by negative numbers. calvin played three games of golf during
a tournament. his score for each game is shown in the table.

part a

a

b
calvin's score changed from game 1 to game 3 by -1.

c

depends on how many days you are talking about

step-by-step explanation:

but there’s no any figure there!

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
