Answer:
k = 1/2
Step-by-step explanation:
direct variation equation is y = kx where 'k' is the constant of variation
substitute 36 for 'y' and 72 for 'x' to get:
36 = 72k
solve for 'k' to get:
k = 36/72 or k = 1/2
Answer:
Step-by-step explanation:
(9x700)+(9x80)+(9x7)

Answer:
Step-by-step explanation:
Actually, none of these represent direct proportion, because each one involves adding or subtracting an offset.
The last answer is closest to being a proportional relationship:
$1.75 per pound → Total cost = ($1.75/lb)x, where x is the number of pounds. This line would go through the origin, as it must, for the relationship to be proportional. But as soon as we add in or subtract that $1 coupon, this is no longer a proportional relationship.
Note that 3 is located on the left, and is in the tens place.
Note that 4 is located on the right, and is in the ones place.
Therefore, 8 being in the ones place will be located on the right, and because there is only one digit, the tens place would have a 0.
D) 0|8 is your answer
