Answer:
10
Step-by-step explanation:
![8.25 + \frac{1}{4} w = 10.75](https://tex.z-dn.net/?f=8.25%20%2B%20%20%5Cfrac%7B1%7D%7B4%7D%20w%20%3D%2010.75)
Subtract 8.25 from both sides.
![\frac{1}{4} w = 2.5](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20w%20%3D%202.5)
Multiply by 4 in both sides.
![w = 10](https://tex.z-dn.net/?f=w%20%3D%2010)
The answer is $9.59 as one bag is $1.37 so time that by seven and you get that
Answer:
The point of intersection of the two functions is not on
the line y = x, therefore, the functions are not inverses of
each other
Step-by-step explanation:
For two functions to be inverse of each other, they must be a reflection of each other in the line y=x.
This means that there must be a point on both the line y=x where both functions will intersect.
From the given graph the two straight lines did not intersect on y=x.
Therefore the correct answer is the point of intersection of the two functions is not on
the line y = x, therefore, the functions are not inverses of
each other
Answer:
548
Step-by-step explanation:
it would be 578 - 30 which equals 548
Answer:
Step-by-step explanation:
a)![4x^3 -7x+2](https://tex.z-dn.net/?f=4x%5E3%20-7x%2B2)
This is not a rational expression.
This is a polynomial with 3 terms.
b)![3x^5+4x-6](https://tex.z-dn.net/?f=3x%5E5%2B4x-6)
This is not a rational expression because the denominator is constant =1
This is a polynomial with 3 terms.
c)![(7x^2+3)(5x+1)](https://tex.z-dn.net/?f=%287x%5E2%2B3%29%285x%2B1%29)
This is not a rational expression because the denominator =1, a constant. This is a polynomial with 4 terms.
d)![9x^2-6x+1 divided by 5x+7](https://tex.z-dn.net/?f=9x%5E2-6x%2B1%20divided%20by%205x%2B7)
This is a rational expression because the denominator contains a variable.
e) ![8x^4-x^3+6x^2-3x+9](https://tex.z-dn.net/?f=8x%5E4-x%5E3%2B6x%5E2-3x%2B9)
This is not a rational expression because the denominator contains a constant 1
This is a polynomial with 5 terms.
