The capital of Wyoming is Cheyenne
Multiply $14.89 by 0.05 to find the tax.
Use $15 to estimate the sales tax: divide $15 by 20 to get 75c, which is 15/20=3/4 of 100 cents.
The estimate for the total price is therefore $15.75.
Equations
• x² + y = 0 ... (1)
• x² - 4x - y = 0 ... (2)
Answer -> (x, y) = (2, -4)
Step-by-step solution:
From equation 2,
-> y = x² - 4x ... (3)
• Substitute y into equation 1
-> x² + (x² - 4x) = 0
-> 2x² - 4x = 0
-> 2x² = 4x
-> x²/x = 4/2
-> x = 2
• Put x = 2 in equation 3
-> y = (2)² - 4(2)
-> y = 4 - 8
-> y = -4
