Answer:
Step-by-step explanation:
For |x|=5, x can be either 5 or -5.
For |x|=-5, absolute value cannot be negative, so it is no solutions.

Answer:
(-6, -7)
Step-by-step explanation:
Given the equations:
y = -1/6x - 8
y = 2x + 5
When graphed, we get a solution, or point of intersection, at (-6, -7). This is the point at which the two equations are equal to each other. This can even be proven:
-7 = -1/6(-6) - 8
-7 = 1 - 8
-7 = -7
----------------------
-7 = 2(-6) + 5
-7 = -12 + 5
-7 = -7
Thus, proving graphically and algebraically, the solution is at (-6, -7).
Hey there! :)
The formula for finding area of a circle is: π · r²
<em>Remember that diameter is 2x the radius. To find radius when given diameter, divide by 2.</em>
d = 26
26 ÷ 2 = 13
_____________________________________________________________
r = 13
13² = 13 × 13 = 169
169 × 3.14 = 530.66
The area of the swimming pool is 530.66 ft
Hope this helps :)
