The area of the portion of S lying outside R is 63xy
<h3>What is a Rectangle ?</h3>
A rectangle is a polygon with four sides , four angles and four vertices , It has opposite sides parallel and equal.
It is given in the question that
A rectangle R has width x and length y.
A rectangle S is formed from R by multiplying each of the sides of rectangle R by 8
Area of R is xy
Area of S is 8x * 8y = 64xy
The area of the portion of S lying outside = 64xy - xy = 63xy

There are 45 pounds and 30 pounds of each type respectively.
Step-by-step explanation:
Since we have given that
Cost of first type = $2 per pound
Cost of second type = $7 per pound
Cost of mixture = $4 per pound
So, we need to find the quantity of each type to make 75 pounds of a blend.
We will use "Mixture and Allegations":
First type Second type
2 7
4
---------------------------------------------------
7 - 4 : 4 - 2
3 : 2
So, Quantity of first type would be

Quantity of second type would be

Hence, there are 45 pounds and 30 pounds of each type respectively.
Answer:
3 kilograms
Step-by-step explanation:
one is for liquids and the others are too small i think
by the inverse function definition, we will have that:
<h3>How to find the values of the inverse function?</h3>
Remember that, by definition, for an invertible function f(x) we have that:
f(x) = y
then:
f⁻¹(y) = x
Where f⁻¹(x) is the inverse function of f(x).
Now, we want to find:
f⁻¹(-2) and f⁻¹(1)
If you look at the given table, we can see that we have the points (3, -2) and (0, 1), which means that:
f(3)= -2
f(0) = 1
Then, by the inverse function definition, we will have that:
