Nx1.5+1.5
+1.5 +1.5 +1.5
3, 4.5, 6, 7.5
Answer:
A
Step-by-step explanation:
To calculate the scale factor k, find the ratio of corresponding sides
= 
= 6
= 
= 6
Hence the scale factor k = 6 → A

Answer:
$7.10
Step-by-step explanation:
Step 1: We make the assumption that 35.5 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=35.5$.
Step 4: In the same vein, $x\%=20$.
Step 5: This gives us a pair of simple equations:
$100\%=35.5(1)$.
$x\%=20(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
Step 7: Taking the inverse (or reciprocal) of both sides yields

No. To test whether a graph is a function or not you do the vertical line test where if a vertical line touches more than one point it is not a function
