Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
3x - 6y = - 12 → (1)
x - 2y = 10 → (2)
Rearrange (2) expressing x in terms of y by adding 2y to both sides
x = 10 + 2y
Substitute x = 10 + 2y into (1)
3(10 + 2y) - 6y = - 12 ← distribute left side
30 + 6y - 6y = - 12 ( subtract 30 from both sides )
0 + 6y - 6y = - 12 - 30 , that is
0 = - 42 ← not possible
This indicates that the system of equations has no solution.
The 2 lines must therefore be parallel with no intersection
70 degrees, hope this helped.
Answer:
sarah is incorrect.
Step-by-step explanation:
She is incorrect because a fraction of a fraction is never going to lead to a whole number. For example, 1/3 times 1/3, you will get 1/6. The fraction will always get smaller, not bigger.
Answer: A=-2
Step-by-step explanation:
AB=11
B=9
B-11=A
9-11=A
A=-2
