Answer:
John I did my phone in a while and my mom did it I was so
Step-by-step explanation:
F(x)=2X/3+4
f(x)=-1X/4+5/2
For this case we have the following inequations:
1.5x-1> 6.5
7x + 3 <-25
Clearing x from each one we have:
For 1.5x-1> 6.5:
1.5x> 6.5 + 1
1.5x> 7.5
x> 7.5 / 1.5
x> 5
For 7x + 3 <-25:
7x <-25-3
7x <-28
x <-28/7
x <-4
The solution set is:
(inf, -4) U (5, inf)
Answer:
See attached image
15. 55x + 125
14. .90x + 2.50
