Answer:
(-1,2)
Step-by-step explanation:
I think 5X+1x. Sorry if it's wrong.
First find the length of the room by dividing the area by the width:
99 / 9 = 11
2 walls would be 9 feet and 2 walls would be 11 feet.
Perimeter is the sum of the 4 walls:
11 + 11 + 9 + 9 = 40 feet
Domain of y = sqrt(x + 6) - 7 <br><br>
Finding domain is trying to check the following valid conditions <br>
<br>
condition 1: check for x such that the value in square root must greater or equal to 0 <br>(applicable here) <br>x + 6 >= 0<br>x > -6 ... this is the answer<br><br>
condition 2: check for x such that the divisor must not be zero <br>(not applicable here) <br><br>
condition 3(misc) : check some functions <br>for example ... log(0) is invalid...<br>
The value H makes the equation true
