The solution set of the given system of equations is (-5, 1).

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that on a coordinate plane, a line goes through (negative 5, 1) and (0, 3) and another line goes through (negative 5, 1) and (negative 4, 0).

The point of intersection represents the solution set of the given set of equations.

Therefore, the solution set of the given system of equations is (-5, 1).

How do i measure the diameter of a circle?

Answers

Answer:

Step-by-step explanation:

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

there’s 2 basic cases you’ll see to find the diameter (a line that basically cuts the circle in half)

you’ll either be given the radius (the distance between the center of the circle to any point on the circle) or the circumference (the perimeter of the circle)

so you have two equations:

diameter= 2*radius

circumference= diameter * pi

if they gave you the radius, simply multiply by 2 as the first equation states. if they give you the circumference, divide the circumference by pi (which is approx. 3.14)

Answers

Answer:

See the answer below.

Step-by-step explanation:

The Pythagoras theorem for a right triangle is

c^2 = a^2 + b^2     where c = hypotenuse and a, b are the legs of the triangle.

3  positive integers which fit this formula  are called Pythagorean Triples.

3,4 5 are a triple because 5^2 = 3^2 + 4^2 ( 25 = 9 + 16).

and also  17^2 = 15^2 + 8^2  ( 289 = 225 + 64).

Step-by-step explanation:

Pythagorean theorem is [tex]a^{2} + b^{2} =c^{2}[/tex] (c being the largest number)

Pythagorean triples are 3 positive numbers that make this equation true.

let's start with 3,4,5

3²+4²=5²

9+16=25

25=25

Since it's true, it's a triple.

Now 8,15,17

8²+15²=17²

64+225=289

289=289

This is also true, so it's also a triple

Hope this helps!

A bag of pennies weighs 5.1 kilogram. Each penny weighs 2.5 grams. About how many pennies are in the bag?

A. 20
B. 200
C. 2,000
D. 20,000

Answers

Answer:2K

Step-by-step explanation:since one kilogram is 1,000 grams and there 5.1 kL it’s 5,100 grams so about 2,000 pennies

Answer:

C, 2000

Step-by-step explanation:

First convert kilo grams into grams, there are 1000 grams in 1 kilogram, the prefix "kilo" means thousand. if you multiply 5.1 times 1000 you will get 5100 grams in the bag. Divide this by the weight of the penny, 2.5, to get 204. The question asks "About how many pennies are in the bag?" so we know to round to the closest answer being c.
