<span>The factors of 12 are : 1, 2, 3, 4, 6, 12.
The factors of 15 are : 1, 3, 5, 15.
1 and 3 are the only common factors (numbers which are factors of both 12 and 15).</span>
<span>Therefore, the highest common factor of 12 and 15 is 3.</span>
Answer:
Option D
Step-by-step explanation:
To check whether (-2,2) is a solution to the system, let us substitute these values and check.
A. 3x − y = −4
5x − y = −8
3(-2)-2=-8 is left side not equal to right side.
B. 3x − y = −4
5x + y = −8
Since I equation is not satisfied not the matching system
C.3x + y = −4
5x − y = −8
I equation gives 3(-2)+2=-4
5(-2)-2 =-12
Since I equation is not satisfied not the matching system
Since II equation is not satisfied not the matching system
D. 3x + y = −4
5x + y = −8
3(-2)+2=-4
5(-2)+2=-8
Thus D is the system which has solution (-2,2)
