Answer:

Step-by-step explanation:
Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is
f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49
g(- 4) = (- 4)² + 12 = 16 + 12 = 28
Then

Answer:
10* 299.99=2999.9
2999.9/100=29.999
this would round up to 30, so Brittany saved $30. : )
 
        
             
        
        
        
Answer:
5x - y = 27
Step-by-step explanation:
Slope is the direction of line and it is calculated as,

where (x₁, y₁) is any two points on the line.
Here, we have given that
Slope = 5  and (x₁, y₁) = (5, -2)
∴  
⇒ 5(x - 5) = y + 2
⇒ 5x - 25 = y + 2
⇒ 5x - y = 27
Hence, the equation of a line is: 5x - y = 27
