Answer:
15:10
Step-by-step explanation:
Method 1: 5 lots of 3:2 →5 × (3:2) = (5×3) : (5×2) = 15:10
 Method 2: 3/2 × 1 → 3/2 ×5/5 = 3×5 2×5= 15:10

Answer:
C
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = E(- 2, 2) and (x₂, y₂ ) = F(4, - 6)
EF = 
     = 
     = 
     =  = 10 → C
 = 10 → C

Answer:
y+1=5/2(x+2)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-6-(-1))/(-4-(-2))
m=(-6+1)/(-4+2)
m=-5/-2
m=5/2
y-y1=m(x-x1)
y-(-1)=5/2(x-(-2))
y+1=5/2(x+2)
