Considering the given equation of the circle, the true statements are given as follows:
- The radius of the circle is of 3 units.
- The center of the circle lies on the x-axis.
- The circle has the same radius as the circle with equation x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center 
and radius r is given by:
The equation given is:
x2 + y² - 2x - 8 = 0.
Completing the squares, the equation is given as follows:
(x - 1)² + y² = 8 + 1
(x - 1)² + y² = 9.
Researching the problem on the internet, the true statements are:
- The radius of the circle is of 3 units.
- The center of the circle lies on the x-axis(
).
- The circle has the same radius as the circle with equation x² + y² = 9.

Step-by-step explanation:
2x - 3y - 2z = 4
[2] x + 3y + 2z = -7
[3] -4x - 4y - 2z = 10
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -3y - 2z - 7
// Plug this in for variable x in equation [1]
[1] 2•(-3y-2z-7) - 3y - 2z = 4
[1] - 9y - 6z = 18
// Plug this in for variable x in equation [3]
[3] -4•(-3y-2z-7) - 4y - 2z = 10
[3] 8y + 6z = -18
// Solve equation [3] for the variable z
[3] 6z = -8y - 18
[3] z = -4y/3 - 3
// Plug this in for variable z in equation [1]
[1] - 9y - 6•(-4y/3-3) = 18
[1] - y = 0
// Solve equation [1] for the variable y
[1] y = 0
// By now we know this much :
x = -3y-2z-7
y = 0
z = -4y/3-3
// Use the y value to solve for z
z = -(4/3)(0)-3 = -3
// Use the y and z values to solve for x
x = -3(0)-2(-3)-7 = -1
Solution :
{x,y,z} = {-1,0,-3}

it might be b and d
Step-by-step explanation:
Finance charge is a fee that represents the cost of borrowing or credit.
In this equation, it shows the total amount paid through credit subtracted by the cost of vehicle.
let x be the finance charge
x = $4,100 + 36 months ($251.34/month) - <span>$11,578
</span>x = $4,100 + $9,048.24 - <span>$11,578 </span>
x = ($4,100 + $9,048.24) - $11,578
x = $13,148.24 - $11,578
x = $1,570.24.
The finance charge is $1,570.24
