Mathematics
1 answer:
Usimov [2.4K]2 years ago
3 0

Constant: 1

Degree: 2

Coefficient : 3 and -4

Algebraic expression: 3x^2-4x + 1

Variable : x

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

3x^2-4x + 1

We have to find the constant, degree, coefficient , algebraic expression and varibale

<h3><u>Constant:</u></h3>

In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number like 1, 2

In the given expression, constant is 1

<h3><u>Degree:</u></h3>

The largest exponent the variable has in a polynomial with one variable

In the given expression, largest exponent is 2

Thus degree of polynomial is 2

<h3><u>Coefficient:</u></h3>

The coefficients are the numbers that multiply the variables or letters

In 3x^2-4x + 1 , coefficients are 3 and -4

<h3><u>Algebraic expression:</u></h3>

An algebraic expression is a mathematical expression that consists of variables, numbers and operations.

Here the algebraic expression is:

3x^2-4x + 1

<h3><u>Variable:</u></h3>

The letters x, y, and z are common generic symbols used for variables.

Thus the variable in given expression is x

zloy xaker [14]

Answer:

B

Step-by-step explanation:

We can divide using the calculator by entering in 59, 584 first followed by 14 before the division sign.

We can also perform long division:

A woman bought some large frames for $10 each and some small frames for $5 each add a closeout sale if she bought 20 frames for
vampirchik [111]

Answer:

The quantity of large frames is 7

The quantity of small frames is 13

Step-by-step explanation:

Given as :

The price of each large frames = $ 10

The price of each small frames = $ 5

The total number of both frames bought = 20

The price for both the frames = $ 135

Now,

Let the quantity of large frames = L

And The quantity of small frames = S

So , According to question

The total number of both frames bought = 20

Or, The quantity of large frames + the quantity of small frame = 135

Or, L + S = 20         ......A

And $ 10 L + $ 5 S = $ 135                         ................B

Or, $ 10× ( L + S ) = $ 10× 20

Or, $ 10 L + $ 10 S = $ 200

(  $ 10 L + $ 10 S ) - ( $ 10 L + $ 5 S ) = $ 200 - $ 135

Or , ( $ 10 L - $ 10 L ) + ( $ 10 S - $ 5 S ) = $ 65

Or, 0 + 5 S = 65

∴  S = \frac{65}{5}

I.e S = 13

So, The quantity of small frames = S = 13

Put the Value of S in eq A

So , L + S = 20

Or, L = 20 - S

Or, L = 20 - 13

∴   L = 7

So, The quantity of large frames = L = 7

Hence The quantity of large frames is 7

And   The quantity of small frames is 13   Answer

20 Points! Which ordered pair is the best estimate for the solution of the system of equations?
yan [13]

Answer:

The best estimate for the solution is the ordered pair  (-6.5,-3.5)

Step-by-step explanation:

we have

y=\frac{3}{2}x+6 ------> equation A

y=\frac{1}{4}x-2 ------> equation B

we know that

using a graphing tool, the solution of the system of equations is the intersection point both graphs

The intersection point is (-6.4,-3.6)

therefore

The best estimate for the solution is the ordered pair  (-6.5,-3.5)
