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.
Answer:
3000
Step-by-step explanation:
640x3 = 1920
90x12 = 1080
Answer:
35°
Step-by-step explanation:
The important information is that the angle is complementary to the angle 55°. A complementary angle is and angle plus another that equal 90°.
55° + x° = 90°
x = 35°
Commutative property of multiplication is just mixing up the order but the answer stays the same.
Examples: 4 + 5 + 6 = 6 + 4 + 5 ; (a)(d) = (d)(a) ;
Answer:
(-16)(y) or/and (y)(-16)
If you look at the hundereds place you see it is under the number 5 which means you would drop 1, 5, & 9 and the answer would be 105,000. If the number was above 5 you would have had to make it 106,000.
