Determine whether y varies directly with x. If so, find the constant of variation and write the equation.
kotykmax [81]

Answer: B. No

Step-by-step explanation:

Direct variation has the following form:

y=kx

Where the constant of variation is "k".

By definition, in direct variation, when the variable "x" changes, tha variable "y" changes in proportion to the variable "x".

As you can observe in the table, when the value of the variable "x" increase, the values of the variable "y" decrease, therefore we can conclude that it is not a direct variation.

Then the answer is the option B.

Estimate the sum of 23 and 71
Natali [406]
Estimation:

23 --> rounded to 20
71 --> rounded to 70
70 + 20 = 90. I rounded both numbers down so the exact sum must be only a little greater than my estimate.
