X>44
.25(x)-3-4>4
.25(x)-7>4
.25(x)>11
x>11
Answer: 
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[switch x and y]
[subtract both sides by 3]
[multiply both sides by 2]

Now, we know that
.
Answer:
1(x - 2xz - 2xy + 4y²)
Step-by-step explanation:
I notice that no term all of them have. which means itbwill be factorised via 1.
1(x - 2xz - 2xy + 4y²)
(5q2 − r2s)(25q^4+5q^2r^2s+1r^4s^2)
