Answer:
12
Step-by-step explanation:
Answer:
x=-15, y=25. (-15, 25).
Step-by-step explanation:
2x+3y=45
x+y=10
--------------
x=10-y
2(10-y)+3y=45
20-2y+3y=45
20+y=45
y=45-20
y=25
x+25=10
x=10-25
x=-15
Answer:
C. 4
Step-by-step explanation:
Since this one is already graphed and we can see it clearely we can just count, but you can also do change in y over change in x (aka "rise over run") to find the slope.
So, we count and find it is four up and one over. 4/1 = 4 = c
Hope this helps, have a nice day! :)
