An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
Answer:
-2/3
Step-by-step explanation:
Where 2 lines are perpendicular, the slope of one = - 1 / slope of the other.
Thus the slope of the red line is - 1 / 3/2
= -2/3

Answer:
what is the question
Step-by-step explanation:
Answer:
5/12 + 8/12 = 13/12 = 1 1/12
Step-by-step explanation:
This is the answer because:
1) You have to add the fractions, in order to add the fractions you have to find the common denominato.
2) The common denominato is 12 because 2 x 4 = 8 and 3 x 4 = 12. Therefore, 2/3 = 8/12.
3) Finally, once you add 5/12 and 8/12, you should get 13/12 which is also equal to 1 1/12.
Hope this helps! :D
