Plug in -8 for x to get 8(-8)+8y=-48. then you have -64+8y=-48. add 64 to the right side of the equation to get 16. now you have 8y=16. divide by 8 to have the variable by itself so y=2.
All you need to do is find (f+g)x = (12x) + (10(1.2)X) which = 24x
then in the multiple choice, see which one equals 24x, in this case its C.
5*1.2=6, 6x+6x = 12x*2 = 24x
Answer:
No, because one x-value corresponds to two different y-value.
Step-by-step explanation:
On the X side of the table you can see two sixes but the two sixes corresponds to two different numbers on the Y side of the table.
