Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 9 from both sides
x + 9 (-9) = -4 (-9)
x = -4 - 9
x = -13
-13 is your solution
hope this helps
Answer:
A.
(x - 5)^2 + (y + 8)^2 = 4
Step-by-step explanation:
The equation for a circle in center radius form is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We need to determine the radius, from the two points which is the distance
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (5-5)^2+( -8--6)^2)
= sqrt(0+ (-8+6)^2)
= sqrt( 0+(-2)^2)
= sqrt(4)
= 2
The radius is 2 and the center is (5,-8)
(x-5)^2 + (y--8)^2 = 2^2
(x-5)^2 + (y+8)^2 = 4
Answer:
Step-by-step explanation:
First sequence : 10,9.5,9,8.5,...
Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5
So on and so on. So, the common difference between these numbers are 0.5
Next sequence : 200,100,50,25, ...
We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.
200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25
So on and so on. So, the common ratio of these numbers are 1/2.
Answer:
5.8%
Step-by-step explanation:
4 L = 4,000 mL
232 mL/ 4000 mL = .058 = 5.8%
