Answer:
A) 5
Step-by-step explanation:
The coefficients of the second equation are 1/3 of those of the first equation. If the constant of the second equation is also 1/3 of the constant of the first equation, then the equations are <em>dependent</em>, and will have an infinite number of solutions.
The constant must be something other than 1/3·15 = 5 to make the equations <em>inconsistent</em>, having no solutions.
Answer:
c
Step-by-step explanation:
I think its c because there is no relation between 2x-1 and 4-x ,it is not equals its + because there is no equals in a straight angle
Two lines are "inconsistent" if they are parallel. They are "equivalent" if they are the same line. Otherwise, they are "consistent."
Your first 3 graphs show "consistent" equations.
The 4th graph shows "inconsistent" equations.
The solution shown on the 5th graph is where the lines intersect, near point
(5, 3)
Determinant = b² - 4ac = (-10)² + 4*1*25 = 100 - 100 = 0
So it has 1 solution.
Answer is D
