Answer - c </= 4 or c >/= -3
2c - 1 </ 7
2c - 1 + 1 </= 7 +1
2c </= 8
2c/2 </= 8/2
c </= 4
2c - 1 >/= - 7
2c - 1 + 1 >/= -7 + 1
2c >/= -6
2c/2 >/= -6/2
c >/= -3
Answer:2(xy-7)= -20
Step-by-step explanation:
Plug in -1 for x and 3 for 3, as the question says that x and y represent those values.
2(xy-7) = ?
2((-1)(3) - 7) = ?
2(-3-7)=?
2(-10)
-20
2(xy - 7) = -20
Answer:
10
Step-by-step explanation:
