Answer:
![\left[\begin{array}{cc}6&18\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D6%2618%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
To find the product of the matrices: ![\left[\begin{array}{cc}4&2\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D4%262%5C%5C%5Cend%7Barray%7D%5Cright%5D)
× ![\left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%265%5C%5C7%26-1%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply rows of the first matrix by the columns of the second matrix.
(4 × (–2) + 2 × 7 4 × 5 + 2 × (–1))
After simplifying this, we get the product
Hence, × =
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 1) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m = 
= 
=
Answer:
True - The above statement is true
A circle is the collection of points in a plane that are the same distance from a given point in the plane.
Step-by-step explanation:
- <em><u>A circle is the set of points in a plane that are a given distance from a given point in the plane. The given point is the center of the circle, and the given distance is the radius.</u></em>
- In other words; A circle is the set of points in a plane that are equidistant from a given center point. Therefore; the locus of points at a fixed distance, d, from the point, P is a circle with the given point P as its center and d as its radius.
