Given:
Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).
To find:
The y-coordinate of the midpoint of line segment YZ.
Solution:
Midpoint formula:

The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:



Therefore, the y-coordinate of the midpoint of line segment YZ is -1.
Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2
Answer:To find 85% of a number multiply the number by .85
Step-by-step explanation: .85 = 85%
Answer:
Dimensions of a matrix:
r × c
Where r is the no. of rows and c is the no. of columns
If A has 4 rows (horizontal) and 3 columns (vertical),
Dimensions are: 4 × 3
If A has 3 rows (horizontal) and 4 columns (vertical),
Dimensions are: 3 × 4
