Lorico [155]3 years ago
4 0

Answer:

The given expressions x+3(7-x) and x+21-3x  are equivalent by using the distributive property

Step-by-step explanation:

Given expressions are x+3(7-x) and x+21-3x and also given that they are equivalent

To find for what property the given two expressions are equivalent :

x+3(7-x)=x+3(7)+3(-x)

=x+21-3x ( here we are using the distributive property a(x+y)=ax+ay )

Therefore the given expressions x+3(7-x) and x+21-3x  are equivalent by using the distributive property

gayaneshka [121]

Answer:

1. a

2. f^{-1} (x)=\frac{x}{2} +2

Step-by-step explanation:

1. Since there is one value of y for every value of x in (−1,0),(−4,5),(3,2),(−3,5), this relation is a function.

2. To find the inverse, interchange the variables and solve for y.

f^{-1} (x)=\frac{x}{2} +2
