Answer:
-162
Step-by-step explanation:
x²+24x-18=x²+24x+12²-12²-18=(x+12)²-162
(x+12)²≥0
(x+12)²-162≥-162
⇒ the minimum value of the function is -162
It’s going to be C because it’s false on all the other ones so yeah
The system has a unique solution. Because the augmented matrix can be reduced to the form of the identity matrix.
<h3>What exactly is a linear system?</h3>
It is an equation system in which the maximum power of the variable is always 1. A figure with only one dimension and no breadth. It is made up of infinite dots placed side by side.
The augmented matrix must be reduced to the form of the identity matrix since there are three pivots one in each row.
Whatever is on the opposite side of the equal sign, there is a solution that is specific and exists.
Hence, the system has a unique solution.

y= -3x - 1
Step-by-step explanation:
Answer:
Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle.
Explanation:
A line intersecting a circle in two places is referred to as a secant. The portion of the secant contained within the circle is called a chord.
This means that both chords and secants intersect the perimeter of a circle twice, chords are entirely inside the circle, and secants extend through a circle to the outside.
