On a map, there are 3 centimeters between two cities. the actual distance between the cities is 45 kilometers.
what was the scale used for the map?
1 cm = 15 km
1 cm = 135 km
1cm = 10 km
15 cm = 1 km
next question
ask for
turn it

1 cm = 15 km

Step-by-step explanation:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
