Turn 5% into a decimal which is 0.05, then multiply by 2.95 = 0.1475
round it off, which is 0.15
so $0.15 is the tax and if ur looking for the total price then add $2.95 to $0.15
Subtract c and then x = y - c
And that's it!
Answer:
2√2
Step-by-step explanation:
compare this equation with the standard equation of a circle centered at (h, k) with radius r:
(x - h)^2 + (y - k)^2 = r^2
(x - 5)^2 + (y + 7)^2=8
Clearly, r^2 = (radius)^2 = 8, and so the radius, r, is √8, or 2√2
