2 Stephanie adds pennies and nickels to a scale until the mass of the combined coins is 75 grams. Each penny has a mass of 2.5 grams and each nickel has a
mass of 5 grams
Create an equation to model this situation, where is the number of pennies and y is the number of nickels that Stephanie can put on the scale so that the
mass of the combined coins is exactly 75 grams

answer

a the answer hopes this

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
