PLEASE HELPP its solving and graphing inequalities
2 answers:
Answer:
1) x>4
2)x≤3
3)x<3
Step-by-step explanation:
1)2x+5>13
2x+5-5>13-5 subtract 5 from both sides
2x>8 results from the previous step
2x/2>8/2 divide 2 from both sides
x>4 final answer
for graphing on the number line it is a closed circle so draw anything bigger than 4 so an open circle and arrow going on forever from four on
2) 5x-7≤8 add seven to both sides
5x≤15 divide both sides by 5
x≤3
for number line, it will be a closed circle at 3 and an arrow pointing forever into the smaller than 3
3)5>4x-7 add 7 to both sides
12>4x divide by 4 on both sides
3>x
for number line 3 is bigger then x so x will be anything smaller then 3 o a open circle on three and the arrow going smaller them 3
4)5x-1<9 add 1 to both sides
5x<10 divide by 5
x<2
xis smaller then 10 so open circle and on forever lower then 10
