Answer:
None
Step-by-step explanation:
We can eliminate the x's by add the 2 equations :
2y = 18
Divide both sides by 2 :
y = 9
Substitute this value into equation 1 to solve for x :
-3x + (9) = 6
Subtract 9 from both sides :
-3x = -3
Divide both sides by -3 :
x = 1
Substitute these values into equation 2 to check :
-3(1) + 6 = 12 ❌❌
So it has no solution
I think y is always 3 less than x. So for the first blank it would be 3 less than -1, that is -4. That makes the second blank -3. The third -8. And the last, -5.
The equation might be x-3=y
I might be wrong, please tell me if this is correct.
Answer:
a) The arithmetic sequence with common difference 2 that has 8 as the first term.
b) The arithmetic sequence of common difference -5 and first term 15.
Step-by-step explanation:
Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:
8, and (8+2) = 10 Therefore the second term is 10.
Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:
15, and (15 - 5) = 10. Therefore again a 10 as second term.
Answer:
B
Step-by-step explanation:
A linear equation represents a straight line.Thus, the solution of the system of linear equation depends on whether the lines intersect, not intersect or same line.
We have below cases:-
- The lines are non parallel and intersect at exactly one point. In this case we have one solution.
- The lines are parallel and hence never intersect. There is no solution in this case.
- The two lines represents the same line. Hence, infinitely many solutions.
We never got exactly two solutions because two lines can intersect at a single point.
