Answer:
B
Step-by-step explanation:
We see that the line intersects the y-axis at -1.  As a result, we need to choose an equation with -1, either B or C.  We see that the different is the slope.  For choice B, the slope is  , meaning that every unit up equates to 3 blocks to the right.  Counting along the line, we see that this is correct.

Answer:
aₙ = 1/2 x aₙ₋₁     n≥2 
Step-by-step explanation:
aₙ = 1/2 x aₙ₋₁     n≥2  
a₁ = 64
a₂ = 1/2 x 64 = 32
a₃ = 1/2 x 32 = 16
 
        
             
        
        
        
Answer:
Janies' monthly pocket money is $180.
Step-by-step explanation:
Janies' adjusted monthly pocket money:
Initial pocket money = $150
Ratio of new pocket money = 6:5
Let his new pocket money be represented by x,
x:$150 = 6:5
$150 x 6 = x (5)
$900 = 5x
x = 
x = $180
Therefore, Janies' monthly pocket money is $180.
