Here are the prices of some items and the amount of sales tax charged on each in Nevada Cost of item:
10$. Sales tax: 0.46

50$ sales tax: 2.30

5$ sales tax: 0.23

Write an expression for the amount of sales tax charged, in dollars, or an item that costs c dollars.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

just took the test and my answers down below!

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
