What is the explicit formula of a1=-3,d=2

Mathematics
1 answer:
AVprozaik [17]3 years ago
7 0

Answer:

The explicit formula for the given expression is 2 n - 3

Step-by-step explanation:

Here, the first term of sequence  =  -1

The common difference  = 2

In a ARITHMETIC PROGRESSION:

The nth term of a sequence is given as

a(n) =  a + (n-1) d

⇒ Here, a(n)  = -1 + (n-1)(2)

                      = -1 + 2n -2

                       = 2n - 3

or,  a(n)  =  2n - 3

Hence, the explicit formula for the given expression is 2n - 3.

Simplify (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² - 5x + 3y).
prohojiy [21]

The simplified form for (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² -5x + 3y) is (5x² + 0y² - 10x + 4y - 2xy).

<h3>A quadratic equation is what?</h3>

At least one squared term must be present because a quadratic is a second-degree polynomial equation. It is also known as quadratic equations. The answers to the issue are the values of the x that satisfy the quadratic equation. These solutions are called the roots or zeros of the quadratic equations. The solutions to the given equation are any polynomial's roots. A polynomial equation with a maximum degree of two is known as a quadratic equation, or simply quadratics.

<h3>How is an equation made simpler?</h3>

The equation can be made simpler by adding up all of the coefficients for the specified correspondent term through constructive addition or subtraction of terms, as suggested in the question.

Given, the equation is (3x² + 2y² - 5x + y) + (2x² - 2xy - 2y² -5x + 3y)
Removing brackets and the adding we get,
3x² + 2x² + 2y² - 2y² + (- 5x) + (- 5x) + y + 3y + (- 2xy) = (5x² + 0y² - 10x + 4y - 2xy)

Answer:

(4, 4)

Step-by-step explanation:

y = 7/4 x - 3       graph (0, -3) (2, .5), (4, 4) (8, 11).  Draw the line

y = x                        graph (0,0)  (2, 2), (4, 4) , ( -2, -2).  Draw the line

The two lines intersect at point (4, 4)
