Answer:
y=-5x+4
Step-by-step explanation:
First lets find the midpoint of the points (-5,3) and (5,5).
(0,4) is the midpoint by the midpoint formula.
Next we find the slope of the 2 points.
2/10 or 1/5
To find the perpendicular bisector, we need to find the negative reciprocal of the slope, which is -5x. However, we want the line to pass through (0,4), so we make the y-intercept 4.
Therfore, the answer is y=-5x+4

Answer:
322.24 meters
Step-by-step explanation:
The scale is 4 meter per centimeter. Multiply 5.3 by 4 to get 21.2 meters. Multiply 5.3 by 4 to get 15.2 meters. Multiply 21.2 by 15.2 to get 322.24
Answer:
7 girls can go in the first place, 6 in the second, etc.
7! ways is the number of ways to arrange the girls.
likewise the boys can be arranged in 7! ways
The total number of ways becomes 7! * 7!
7! * 7! = 25,401 600 ways
I honestly don't know any of this so
