Answer:
Option c) is correct.
That is x-5y=12 and 3x+2y=-15 are the system of linear equations satisfies the point (-3,3) so this is the solution.
Step-by-step explanation:
To verify that which system of linear equations having the solution (-3,-3)
Let
and
To solve it we have to use elimination method
First multiply the equation(1) into 3 we get
Now subtracting the equations (2)and (3) the signs may vary in the second equation we get
________________
_______________
Now substitue the value y=-3 in equation (1) we get
Therefore x=-3
Therefore the solution is (-3,-3)
Therefore Option c) is correct.
That is x-5y=12 and 3x+2y=-15 are the system of linear equations satisfies the point (-3,3) so the solution is (-3,-3).
Answer:
Step-by-step explanation:
The sum of two even numbers is an even number
Answer:
228,000
Step-by-step explanation:
I = PRT / 100
- I = Interest
- P = principle = 200,000
- T = time = 1.75 yr
- R= rate = 8
I = (200,000 * 8 * 1.75 ) / 100
I = 28,000
Amount to be paid = 228,000
