-11
Step-by-step explanation:
The Midpoints of the line segment is (2, 5/2)
Step-by-step explanation:
The line is defined by starting and ending coordinates.
As given in the question starting coordinates are given as (3,-2) and the ending coordinates are provided as (1,7)
The midpoint of the life segment-
The midpoint of the line can be found by individually finding of each “x” and “y” coordinate from both ends.
Thus, x coordinate of the midpoint is (3+1)/2= 2
Similarly, the Y coordinate of the midpoint is (-2+7)/2 = 5/2
Hence the Midpoint of the life segment- (2, 5/2)
Answer:
<h2>x² - 14x - 15 = (x − 7)² − 64</h2><h2>Then the coordinates of the vertex are (7 , -64)</h2>
Step-by-step explanation:
x² - 14x - 15 = x² - 14x + (49 - 49) - 15
= (x² - 14x + 49) - 49 - 15
= (x² - 14x + 7²) - 49 - 15
= (x − 7)² − (49 + 15)
= (x − 7)² − 64
x² - 14x - 15 = (x − 7)² − 64
Then the coordinates of the vertex are (7 , -64)
Answer:
^algebra^
#1). a - b=4
a=4 + b .....(equation 1)
#2) a + b=12
(4 + b) + b= 12
4 + b + b=12
4 + 2b=12
2b= 12 - 4
2b =8
b= 8:2
b=4
subtituted b in equation 1
a= 4 + b
a= 4 + 4
a=8
so, the number is 8 and 4
