The answer is quadratic.
A quadratic equation takes this form:
<em>ax^2+ bx + c</em>
The "a,""b,"and "c" represent numerical coefficients.
This is how your equation looks:
3x + x^2 + 4
Now it is standard that we organize the polynomial in descending order so it will look like this:
x^ 2 + 3x + 4
(commutative property of addition says that the arrangement will not affect the result)
It matches the quadratic polynomial form.
<em>* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed. </em>
Answer:
Cost of one chair = Rs . 150
Cost of one table = Rs. 500
Step-by-step explanation:
Let number of chairs denote x and no of tables denote y
4x + 3y = 2100 --------------------(i)
5x +2y = 1750 ------------------(ii)
Multiply equation (i) by 2 and (ii) by (-3) and now y will be eliminated.
(i)*2 8x + 6y = 4200
(ii)*(-3) -<u>15x - 6y = - 5250</u> {Now, add}
- 7x = - 1050
x = -1050/-7
x = Rs. 150
Plug in the value of x inn equation (i)
4*150 + 3y = 2100
600 + 3y = 2100
3y = 2100 - 600
3y = 1500
y= 1500/3
y =Rs 500
0.27 because if you put it like a whole fraction it would be 3/11 and as a decimal it is 0.27
Okay, so his remaining money would have been 20.00 if he spent half of it (10.00) on his lunch. If one third of his money was 20.00, we need to add two thirds more to create the whole amount. 20 + 20 + 20 = 60.00.
At first, he had 60.00
Answer:
<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>
Step-by-step explanation:
Given that the functions f ad g are defined by
and 
respectively.
<h3>To show that the set of polynomials is closed under subtraction :</h3>
Now subtract the given polynomials
∴ 
- When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.
<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>
∴ are closed under subtraction,
Hence showed.
