Question

How do you solve and graph `-4z+13>=29` and `10<6a-14`?

Answer 1

`-4z + 13 >= 29`

isolate the variable

`-4z >= 29-13`

not that the sign changes, because we divided by a negative number

`z <= 16/-4`

`z <= -4`

graph{y <= -4}

`* * * * * * * * * * * * * * * * *`

`10<6a-14`

`10 +14 < 6a`

`24/6 < a`

`4 < a`

graph{y < 4}
