Step-by-step explanation:
A (-3 , 4) and C ( 2 , -6 ) and ratio of AB : AC is 4:5
now , let AB be 4x and AC be 5x such that
AC = AB + BC
AC - AB = BC
5x - 4x = BC
x = BC
ratio of AB : BC = 4:1
by using section formula
( mx2 + nx1 / m+n , my2 + ny1 / m+n )
where m = 4 and n = 1
B = ( 4×2 + 1×-3 / 4+1. ,. 4× -6. + 1× 4 / 4+1 )
B = ( 8 -3 / 5. ,. -24 + 4 / 5)
B = ( 5/5. ,. -20/5 )
B = ( 1. , -4 )
Answer:
(0,-1)
Step-by-step explanation:
Total amount she wants to raise = $3200
Amount she'll get for each kilometer = $35
So, number of kilometers she need to run
= Total amount she wants to raise/Amount she'll get for each kilometer
= $3200/$35
= 91.42....
Since her sponser is will donate only for whole kilometers she'll have to run 92 km.
5 x (4 x 3) = (5 x 4) x 3
7 x (3 x 6) = (7 x 3) x 6
(30 x 5) x 12 = (30 x 12) x 5
first half
Answer:
-12 and -4
Step-by-step explanation:
-12 + (-4) = -16
-12 x -4 = 48
