Simple...
you have: (-2,20) and (3,-10,)
Using
to find slope--->>>
=-6
m=-6
Using y=mx+b to find the equation of the line-->>>(Use any of the coordinates)
(-2,20)
20=-6(-2)+b
20=12+b
20=12+b
-12 -12
8=b
y=-6x+8
Thus, your answer.
Answer:
800m
Step-by-step explanation:
this would be solved using Pythagoras theorem
we are to find the base
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
600² + b² = 100²
b² = 10000 - 3600
b² = 6400
take the square root of both sides
b = 800m
Answer:
Step-by-step explanation:
Step-by-step explanation:
let age of jeff be x, age of keisha be 2x(since keisha is twice as old as jeff) and age of jessica be x+4 (since jessica is 4 years older than jeff)
Now,
x+2x+x+4=60( since sum of all their ages is 60)
or 4x=60-4
or 4x=56
or x=56/4
or x=14
therefore age of jeff=14
age of keisha=2x=2×14=28
age of jessica=x+4=14+4=18
