Both sides are the same so they are equal so...
4x+13=5x-15
x=28
A because 1.6 is less than 2.4, 2.2, and 2.6

A parabola opening up has a positive a value while a parabola opening down has a negative a value
Answer:
for (−4/5)x + 3/10 < 8/10: solution is x > -5/8
for −4/(5x) + 3/10 < 8/10: solution is x > -8/5
Step-by-step explanation:
I'm not exactly sure if you mean -4 divided by 5x or (-4/5)x, so I've done both! :)

subtract 3/10 from both sides: 
Divide both sides by 4/5: 
Divide both sides by -1 (reverse sign): 

subtract 3/10 from both sides: 
Multiply both sides by 5x: 
Divide both sides by 5/2:
