Answer:
$522.49
Step-by-step explanation: 549.99*.05=27.50 (discount)
549.99-27.50=$522.49
 
        
                    
             
        
        
        
The answer is B because it’s not a straight line and x can not have an exponent of 2 bc it will make it nonlinear
        
             
        
        
        
Answer:
9
Step-by-step explanation:
To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2. Ax and Ay are the x and y coordinates for the vertex of A. The same applies for the x and y notations of the B and C vertices.
Fill in the numbers for each corresponding letter combination within the formula. 
Fill in your formula like this: 0(8-10) + 3(0-0) + 9(0-8).
Subtract the numbers within the parentheses.
0 from 8 = 8, 0 from 0 = 0 and 8 from 10 = 2.
Multiply that result by the number to the left of the parentheses.
0 by 8 = 0, 3 by 0 = 0 and 9 by 2 = 18.
Add the three products together. 
0 + 0 + 18 = 18
Divide the sum of the three products by 2.
18 ÷ 2 = 9
 
        
             
        
        
        
Y=mx+b This is the equation, now just plug in the numbers provided to you. 
m=slope        b=y-intercept
y=(-5)(x)+4
