Answer:
16.1km
Step-by-step explanation:
All you need is his total distance (10 miles). Then you use dimensional analysis (or unit multiplying).
Answer:
the slope of the line passing through the points (-4,-4) and (2, 5) m=3/2.
Step-by-step explanation:
Hello!
To find the slope between two points use the formula
- m=(y₂-y₁)/(x₂-x₁)... substitute values
- m=(5-(-4))/(2-(-4))
- m=9/6
- m=3/2

x - y = - 11 .............( 1 )
y + 7 = - 2x ...............( 2 )
from equation ( 1 )
x - y = - 11
x = -11 + y ...........( 3)
putting x in equation ( 2 )
y + 7 = - 2 x
y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7
3 y = 15 y = 15 / 3
putting value of y in equation 3
x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)
x = -17 / 5
check
x = -11 + y
- 17 / 5 = -11 + 13 / 5
-17 /5 = -17 / 5
Answer:
Step-by-step explanation:
A=L^2
4-4x+x^2m^2=L^2
L=√4-4x+x^2
L=2-2x+xm
