(Correct me if I am wrong)
Answer:
8000
Step-by-step explanation:
To solve the equation, it is necessary to isolate the unknown variable "x" first. This is done as shown below:
2x - 3 = 15
Adding 3 to both sides of the equation:
2x - 3 + 3 = 15 + 3
2x = 18
Dividing 2 from both sides:
2x/2 = 18/2
x = 9
Among the choices, the correct answer is B.
X=3. if u want me to explain it i will. yw
Answer:
(x-7)^2 + (y-2) ^2 = 130
Step-by-step explanation:
We need to find the length of the radius
the length of the radius is found by using the distance formula
r = sqrt( ( -2-7)^2+( -5 -2)^2)
sqrt( ( -9)^2+( -7)^2)
sqrt( 81+49)
sqrt(130)
The formula for a circle is
(x-h)^2 + (y-h) ^2 = r^2
where (h,k) is the center and r is the radius
(x-7)^2 + (y-2) ^2 = 130
