Answer:
x = 10
Step-by-step explanation:
Step 1: Write equation
3x - 8 = 22
Step 2: Add 8 to both sides
3x = 30
Step 3: Divide both sides by 3
x = 10
 
        
             
        
        
        
Answer:
B. 55.10
Step-by-step explanation:
Given:
1 pair of Shoes for 1st year = $50
2 pair of Sock for 1st year = $2 each = 2 2= $4
2= $4
 CPI for year 1 = Price of shoes for 1st year + Price of Sock for 1st year= $50 + $4 = $54
 CPI for year 1 = Price of shoes for 1st year + Price of Sock for 1st year= $50 + $4 = $54
Now 
1 pair of Shoes for 2nd year = $51
2 pair of Sock for 2nd year = $2.05 each = 2  2.05 =$4.10
2.05 =$4.10 
 CPI for Year 2 = Price of shoes for 2nd year + Price of Sock for 2nd year= $51 + $4.1 = $55.10
 CPI for Year 2 = Price of shoes for 2nd year + Price of Sock for 2nd year= $51 + $4.1 = $55.10
Hence CPI for Year 2 is $55.10

Answer:
The points are (-1, 1), (2, 7), (1, -1), (3, 0)
Step-by-step explanation:
Let us solve the question
∵ f(x) = y
∴ The coordinates of the point are (x, y)
→ Let us use this fact to find the coordinates of each point
∵ f(-1) = 1
∴ x = -1 and y = 1
∴ The coordinates of the point are (-1, 1)
∵ f(2) = 7
∴ x = 2 and y = 7
∴ The coordinates of the point are (2, 7)
∵ f(1) = -1
∴ x = 1 and y = -1
∴ The coordinates of the point are (1, -1)
∵ f(3) = 0
∴ x = 3 and y = 0
∴ The coordinates of the point are (3, 0)
