Answer:

No solution, D

Step-by-step explanation:

If you rewrite the second one to be the y=mx+b form then you get

8x-14= -2y

Divide by -2 and get

-4x+7=y

Because the slopes are the same the lines will never intersect which means there is no solution

2x – 5 > 3 or 11 – 3x > -2
IRISSAK [1]

Answer:

x > 4 and x <3

Step-by-step explanation:

Given the system of inequalities

2x – 5 > 3 or 11 – 3x > -2

for 2x – 5 > 3

2x > 3+5

2x>8

x>8/2

x> 4

For 11-3x > -2

-3x > 2-11

-3x > -9

x < -9/-3

x<3

hence the result will be x > 4 and x <3
