Answer:
x=12
Step-by-step explanation:
cause then when u add them it's bigger than 17
 
        
             
        
        
        
y = 25x + 50
$50 is a constant, whereas $25 is the daily rate and will vary
let x be the number of days rented, then
y = 25x + 50 ← in slope-intercept form
 
        
                    
             
        
        
        
Answer:
1/2
Step-by-step explanation:
Pick two points on the line
(2,0) and (4,1)
Use the slope formula
m= (y2-y1)/(x2-x1)
   = (1-0)/(4-2)
    = 1/2
 
        
                    
             
        
        
        
Answer:
10.31 pounds
Step-by-step explanation:
First, we multiply 1.3 x 2 because he is gaining 1.3 for the next TWO weeks.
1.3 x 2 = 2.6
Now, add 7.71 + 2.6 because that is the weight he started with.
7.71 + 2.6 = 10.31
Her brother will weight 10.31 pounds if he is 7.71 lbs and continues to gain 1.3 pounds each week for two weeks.
 
        
             
        
        
        
Cos(x°) = (√3)/2
cos⁻¹[(√3)/2] = x°, that means x° = 30°
