: pleae help me solve and graph 6x+8 _>8x-10...note the line should be under the greater than sign...:O) This question is from textbook
You can put this solution on YOUR website! 6x+8 >=8x-10
6x+8-8 >= 8x-10-8
6x >=8x-18
6x-8x >= 8x-8x-18
-2x >= -18
-2x/-2<=-18/-2 [Switch the signs when dividing or multiplying by a negative]
x<=9
.
Check by plugging-in a number that is <= 9.
6x+8 >=8x-10 [Original inequality]
(6)(9)+8 >(8)(9)-10 [Try 9]
62>=62 [Checks out]
.
Check by plugging-in a number that is <= 9.
6x+8 >=8x-10 [Original inequality]
(6)(8)+8 >= (8)(8)-10 [Try 10]
56>=54 [This also checks out]
