Since the 4 is a smaller digit than a 5, the 6 in the tens place would stay the same while the 4 would become a 0.
Answer:
C
Step-by-step explanation:
We have the expression:
Rewriting this yields:
Therefore, our answer is C.
Answer: only (x-y=4) and (x+y=4).
Step-by-step explanation:
Notice target point has y=0, so all terms with y are zero. Then all 6 equations reduce to m x = k, for various m and k. So calculate 4×m and compare to k six times.
x - y = 4 4=4 yes
-x - y = 4 -4=4 no
2x - y = 7 8=7 no
x + y = 4 4=4 yes
2x + y = 7 8=7 no
2x + y = -7 8=-7 no.
