Please don't just take my points I need help plzzz help me

1. Anakin is saving for a Xbox One. He currently has $165 saved and earns $40 per week doing chores around the house. If an Xbox costs $500 plus 10% sales tax, how long will it take for him to save that amount? Write your answer in a complete sentence.

2. Write an equation in slope-intercept form for the previous scenario. Define the domain and range for Anakin. Graph the equation on the coordinate plane. Circle the point at which he has saved enough to purchase the Xbox.

3. For the following system of equations, complete a table of at least 5 points for each equation, then graph the system on the coordinate plane. Describe the solution. y = -3x + 4 6x + 2y - 8 = 0

4. Solve the following system of equations: y - 3x + 15 = 10 6 - 4x = y

5. Create and solve a system of equations for the following scenario: Luke and Leia are selling hot dogs and hamburgers at a minor league baseball game. At the end of the day they determine they have sold a total of 45 items and earned $195. If hot dogs cost $4 and hamburgers cost $5, how many did they sell of each?

6. Graph the following system of linear inequalities. Identify at least two points in the solution:   y < 5 - 2x x + 5y > -7 ​

1) 10 weeks. The total will be $550 after tax, and then you subtract what he has already. You’re left with $385 left to have enough. He’ll have a bit more after the 10th week. It will take 10 weeks to save the amount.
Explanation:
The price of Xbox one = $500
Sales tax = 10%
The total cost of Xbox one = 500 + (10% × 500 )
= 500 + (0.010 × 500)
= 500 + 50
= $550
Anakin currently has = $165
He earns per week = $40
Let the time (in weeks) will take for him to save the amount be t
165 + (40t) = 550
40t = 550 - 165
40t = 385
t =
t = 9.625 ≈ 10 weeks
It will take 10 weeks to save the amount.
