2x+3y=6, what is the rate of change
ankoles [38]

Answer:

-2/3

Step-by-step explanation:

rate of change is slope

so rearrange the equation to get in y = mx + b format

2x + 3y = 6

move the 2x over by subtraction

3y = -2x + 6

The original cost of a necklace is $32. The jewelry store is having a sale and every item is 30% off. A 6.75% tax rate is charge
madam [21]

Answer:

Step-by-step explanation:

Original cost = $32

Discount = 30% of 32

=\frac{30}{100}*32\\\\=\frac{3*32}{10}\\\\=\frac{96}{10}\\\\=9.6\\

Selling price =  32 - 9.60 = $22.40

Tax = 6.75% of 22.40

=\frac{6.75}{100}*22.40\\\\= 1.512

= $ 1.51

Total cost with discount and tax = 22.40 - 1.51 = $ 20.89
