Answer: square root of 10
Step-by-step explanation:
Step-by-step explanation:
Hey there!
The equation is;
Shifting "2x" to left side and "2" to right side.
Simplify them to get answer.
Therefore the value of x is -7.
<u>Check</u><u>;</u>
3 × -7 + 2 = 2 × -7 -5
-19 = -19 ( True ).
So, your answer is option B.

Answer:
(x - 3)^2 + (y + 1) = 25
Step-by-step explanation:
First find the midpoint of the diameter, because that represents the center of the circle.
-1 + 7
The x-coordinate of the midpoint is xm = ---------- = 3
2
2 - 4
and the y-coordinate is ym = ---------- = -1
2
And so the center of this circle is at (3, -1).
Use the Pythagorean Theorem to determine the square of the radius:
square of radius = 4^2 + (-3)^2 = 16 + 9 = 25
And so the equation of this circle is (x - 3)^2 + (y + 1) = 25
What is GH and DE? is there a picture lol
x^2 = 81/100
Let's take the square root of each side
x = 0.9 and -0.9
