Answer:
can i have brainliest? :) hope this helpeddd
Step-by-step explanation:
i don't know what im supposed to match it too but im just gonna solve the equation
2x + 5 = 19
isolate the variable
2x + 5 = 19
-5 -5
2x = 14

Answer: Approximately 112.86 miles in any direction away from the radio station
Step-by-step explanation: If the radio signal of the radio station can cover a circular area of 40,000 square miles, it simply means any direction away from the radio station that is within the coverage area. With the radio station as the center, we would have a radius that can reach any point within the area, and any distance beyond the radius would be out of coverage area. If the area has been given as 40000, then we have;
Area of a circle = pi x r^2
40000 = 3.14 x r^2
By cross multiplication we now have
40000/3.14 = r^2
Add the square root sign to both sides of the equation
112.8665 = r
Therefore, the farthest a person can live away from the radio station is approximately 112.86 miles
wich realation its a function ? A.(6,5)(1,1)(6,4) B.(0,1)(2,3)(2,5) C.(8,-2)(-2,5)(6,0) D.(-2,3)(-5,9)(-5,3)

<span>C. (8, -2) (-2, 5) (6, 0)?
I'm not totally sure.</span><span />
8x+6-9x= 2-x+4
8x+6+-9x=2+-x+4
(8x + -9x) + (6) = (-x) + (2+4) (combine like terms)
-x+6= -x+6
-x+6+x=-x+6+x
6-6=6-6
0=0
here it is :)
do check properly, I have given step by step instructions:)
do give feedback on my answer, would appreciate it!
