Answer:
sales tax rate = 4%
Step-by-step explanation:
In this problem formula to express one term in percentage is used
To express x as percentage of y is given by (x/y*100) %
______________________________________________
Cost of item = $480
sales tax = $19.20
we have to find sales tax rate.
sales tax rate is percentage of cost price which will levied as tax .
thus, we have to find sales tax as percentage of cost price.
using the percentage cost as given above
sales tax as percentage = sales tax/ cost of item *100
sales tax as percentage = 19.20/480 *100 = 4%
Thus, sales tax rate is 4%.
It means that if cost price of item is $100 then $4 will be the sales tax for the item.
Factor and set each factor equal to zero:
x = -3, 3, 2i, -2i
Answer:
y + 4 = -2(x - 3)
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h). Substitute -2 for k and 3 for h, as well as -2 for m:
y + 4 = -2(x - 3).
