Let "per month" = m
The inequality is
1.5m + 4 ≥ 7
+ 4: Her hair right now is 4 cm long
1.5m: Her hair grows 1.5 per month (m)
≥ 7: She wants it to be at least 7 or more.
1.5m + 4 ≥ 7 is your answer

Answer:
sorry kid idontknow
Step-by-step explanation:
{ 3x-2y=2
{ y=2x+8
{ -2y=2-3x
{ y=2x+8
{ y= -1+3/2x
{ y= 2x+8
-1+3/2x = 2x+8
x=-18
y= 2(-18)+8
y= -28
(x,y) = ( -18,-28)
——
Solution check
{ 3(-18)-2(-28)=2
{ -28=2(-18)+8
{ 2=2
{ -28=-28
