Answer:

Interval notation: 
Step-by-step explanation:
<u>First inequality:</u>
<u />
Therefore, this inequality restricts:

<u>Second inequality:</u>

Therefore, this inequality restricts:

Therefore, with both of these restrictions together, we have:
.
Step-by-step explanation:
replace the value of x with 1
y + 0.5 × 1 × y = 1 + 2
do the maths
y + 0.5y = 3
here the value of y is equal to 1. same goes for x, if we have no given value for them.
1.5y = 3
y = 3/1.5
y = 2
S=4P+4Q
S=4(P+Q)
S/4=P+Q
S/4-P=Q
Q=S/4-P
