Answer: No 
Step-by-step explanation: it’s a no because. 19 - 15 does not equal out to 7 19 - 15 is 4 and that’s the wrong answer for 19 -15
hope this helps and is the right answer!
 
        
             
        
        
        
<u>Answer:</u>
4.5 foot is needed for a unit dozen bird house
<u>Explanation:</u>
Given Tina saw ¾ foot of wooden trim is being used for  first 1/6 dozen bird houses
Therefore, we can write as,4
1/6 dozen = ¾ foot
For 1 dozen bird houses, we have to use the unitary method
1/6 dozen = ¾ foot  
Therefore, 1 dozen or unit dozen = 
1 dozen = ¾ * 6 =  foot = 4.5 foot
 foot = 4.5 foot  
Therefore, 4.5 foot is needed for a unit dozen bird house

Answer:
C(x) = 12x + 1680
Slope = 12
Intercept = 1680
Step-by-step explanation:
Given that:
X1 = 60 chairs ; y1 = 2400
X2 = 260 chairs ; y2 = 4800
Obtain the slope ; m
m = y2 - y1 / x2 - x1
m = 4800 - 2400 / 260 - 60
m = 2400 / 200
m = 12
Using the point slope relation:
y - y1 = m(x - x1)
y - 2400 = 12(x - 60)
y - 2400 = 12x - 720
y = 12x - 720 + 2400
y = 12x + 1680
C(x) = 12x + 1680
From the general slope intercept equation :
y = mx + c
m = slope ; c = intercept
Hence, 
C(x) = 12x + 1680
Slope = 12
Intercept = 1680
