Yes, y = 7x-4 is a linear function because the slope is constant and it follows the y= mx + b format of linear equations. Hope this helps! :)
Answer:
x= -1/4
Step-by-step explanation:
suppose ,
The number is x
now,
twice a number = 2 . x = 2x
The product of twice a number and six = 2x . 6 = 12x
[ "product" means the result of multiplication]
Then,
Eleven times the number = 11 . x = 11x
The difference of eleven times the number and 1/4 = 11x - 1/4
= (44x-1)/4
Hence,
12x = (44x-1)/4
=>48x = 44x-1 [multiplied by 4 on both sides]
=>48x-44x=-1 [subtract 44x on both sides]
=>4x=-1 [divide both sides by 4]
=>x= -1/4
As it's already graphed their inetresection point is solution for both functions
- Red one is g(x) as it's linear
- Other one is f(x) as it's modulus
The solution is (1,5)
$771

Answer:
C(x) = 7x + 10
Step-by-step explanation:
If the delivery charge is $10 for any number of board feet ordered.
If the delivery charge is $10 for each board feet ordered, the function would
be C(x) = (7 + 10)x = 17x
