Answer:
x = 7
Step-by-step explanation:
The point-slope equation of the line is ...
y -(-13) = -3(x -3)
Substituting -25 for y, we can solve for x:
-25 +13 = -3x +9
-21 = -3x . . . . add -9
7 = x . . . . . . . divide by -3
-2x + x/4 + 1 = 5
-2x + x/4 = 4
-7x/4 = 4 (By using the same denominator)
x = -16/7
Answer:
so the distance between two points is (2√13)
Step-by-step explanation:
we have to find the distance between two points
d=√(x2-x1)²+(y2-y1)²
putting the values of coordinates
d=√(4--2)²+(-1-3)²
d=√(6)²+(-4)²
d=√36+16
d=√52
d=2√13
i hope this will help you :)
Answer:
7
down
3x-6
Step-by-step explanation:
g(x)=3x-6
f(x)=3x+1
Thus, g(x) is just f(x)-7
Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.
