Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation

2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8

The result is -8, so the pair (3,28) is a solution

Will ran the diagonal distance across a square field measuring 40 yards on each side. James ran the diagonal distance across a r

Oksi-84 [34.3K]

Answer: The distance across a rectangular field is longer distance.

Step-by-step explanation:

Since we have given that

Dimension of square = 40 yards

So, Dimensions of rectangle are :

Length = 25 yards

Width = 35 yards

So, Perimeter of rectangle would be

$2\times (l+b)\\\\=2\times (25+35)\\\\=2\times 60\\\\=120\ yards$

Diagonal of square would be

$\sqrt{40^2+40^2}\\\\=\sqrt{1600+1600}\\\\=\sqrt{3200}\\\\=56.56\ yards$

Hence, the distance across a rectangular field is longer distance.

You are planning on using circles to compare the populations of California 37,691,000, Texas 25,675,000, and New York 19,465,000

Aneli [31]

The areas of the circle will represent the population, so:
Area = πr²

5² : 19,465,000
C² : 37,691,000

California circle radius = 6.96 cm

For Texas:
5² : 19,465,000
T² : 25,675,000

Texas circle radius = 5.74 cm

Which relationship has a domain of real numbers?

babunello [35]

Answer:Domain: all x-values that are to be used (independent values).

Step-by-step explanation:The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).

Explain what terms and degrees are and how. How are they used to classify polynomials? Also explain why this polynomial (4x2y +

user100 [1]

When a polynomial has more than one variable, we need to look at each term. Terms are separated by + or - signs. Find the degree of each term by adding the exponents of each variable in it. The degree of the polynomial is found by looking at the term with the highest exponent on its variables.

Polynomials can be classified in two different ways - by the number of terms and by their degree. A monomial is an expression with a single term. It is a real number, a variable, or the product of real numbers and variables. A polynomial is a monomial or the sum or difference of monomials. A polynomial can be arranged in ascending order, in which the degree of each term is at least as large as the degree of the preceding term, or in descending order, in which the degree of each term is no larger than the degree of the preceding term.

The polynomial $(4x^2y + 5xy)$ is classified as a 3rd degree binomial, because the monomial $4x^2y$ has degree equal to 3 and the monomial 5xy has degree equal to 2. The highest degree is 3, therefore the polynomial $(4x^2y + 5xy)$ is classified as a 3rd degree polynomial. Since polynomial $(4x^2y + 5xy)$ has two terms, then it is classified as binomial.
