Could someone help me plzz :) solve and graph each inequality.
2 answers:
Sorry I wasn't able to do more than one because I don't have time but you can look at my example.< means open cycle and the one I did is less than or equal to so its a close cycle.if you are still confused you can ask me. Hope this helps. please add brainlist
4.
3 + v < -5
Isolate v by subtracting 3 to both sides
(3-3) + v < -5 - 3
v < -8
For the line graph the pic is below (circle is open because it is not an "equal to value" and doesn't include -8 in the answer. It goes to the left because v is anything less then -8)
5.
7 + x ≤ 10
Isolate x by subtracting 7 to both sides
(7 -7)+ x ≤ (10 - 7)
x ≤ 3
For the line graph the pic is below (circle is closed because it is an "equal to value" and does include 3 in the answer. It goes to the left because x is anything less then or equal to 3)
6.
s - 4 < -10
Isolate s by adding 4 to both sides
s + (-4 + 4) < -10 + 4
s < -6
For the line graph the pic is below (circle is open because it is not an "equal to value" and doesn't include -6 in the answer. It goes to the left because s is anything less - 6)
The other person already did #7 so one to 8--->
8.
7 + n > - 2
Isolate n by subtracting 7 to both sides
(7-7) + n > - 2 - 7
n > - 9
For the line graph the pic is below (circle is open because it is not an "equal to value" and doesn't include -9 in the answer. It goes to the right because n is anything greater than -9)
last one I'll do 9.
r + 6 ≥ -1
Isolate r by subtracting 6 to both sides
r + (6-6) ≥ -1 - 6
r ≥ - 7
For the line graph the pic is below (circle is closed because it is an "equal to value" and does include -7 in the answer. It goes to the right because r is anything greater than or equal to -7)
Hope this helped! And good night! I will be logging off for the day!
