Answer:
the system of equations has infinite solution
Step-by-step explanation:
Reese states that the system of equations has no solution because the slopes are the same. Describe Reese’s error. ( y=−3x−1 ), ( 3x+y=−1 )
Solution:
The equation of a straight line graph is given by:
y = mx + b, where m is the slope of the line and b is the y intercept.
A system of linear equations has no solution when the graphs are parallel, that is they have the same slope and different y intercept.
A system of linear equations has infinite solutions when the graphs are the exact same line, that is they have the equal slope and equal y intercept.
The first equation: y = -3x - 1 has a slope of -3 and y intercept of -1.
The second equation: 3x + y = - 1; i.e. y = -3x - 1 has a slope of -3 and y intercept of -1.
Since both equations have equal slope and equal y intercept, hence both equations are infinite solutions.
Therefore the statement that the system of equations has no solution is wrong.

Answer:
Step-by-step explanation:
Since we do not know the base of the logarithm, then we must take the area of permissible expressions, then we denote n as the base ; then n ≠1 ; n>0
