Question

multiple choice 1 point
the triangle has been reflected over the x - axis. find x.
2x + 1
11
x = 6
x = 5
x = 11
not enough information to determine

Explanation:

Step1: Use reflection property

When a point or a shape is reflected over the x - axis, the distance of a corresponding vertical line segment from the x - axis remains the same in magnitude. So, \(2x + 1=11\).

Step2: Solve the equation for x

Subtract 1 from both sides: \(2x=11 - 1\), so \(2x = 10\). Then divide both sides by 2: \(x=\frac{10}{2}=5\).

Answer:

x = 5
