Answer:
a. 2
b. -2
c. 0
Explanation:
An inequality is an equation with more than one solution. In this problem, c should be a value that maintains the initial relationship.
- c(-4)<c(7) let c=2 so 2(-4)<2(7) which is -8<14 and is true.
- c(-4)>c(7) let c=-2 so -2(-4)>-2(7) which is 8>-14 and is true.
- c(-4)=c(7) let c=0 so 0(-4)=0(7) which is 0=0 and is true.
