Answer:
D) x + y ≤ -4
3x + 2y ≤ -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
we will choose the system of inequalities
x + y ≤ -4
3x + 2y ≤ -5
x + y = -4 ...(i)
3x + 2y = -5..(ii)
Multiply equation (i) with '3'
3x + 3y = -12
3x + 2 y = -5
<u> - - +</u>
<u> 0 + y = -7 </u>
<u>Step(ii):- </u>
Substitute y = -7 in equation (i)
x + y = -4
x - 7 = -4
x = -4 + 7
x = 3
<em>The solution of the given inequalities is ( 3, -7)</em>

Answer:
I got 7%
Step-by-step explanation:
110 x .15 = 16.5
110-16.5=93.5
93.5 x .10 = 9.35
93.5 + 9.35= $102.82
Thats the discount price
110 - 102.82 + 7.18
7.18/102 = .0698
.0698 x 100 = 6.98
7%
