The answer is the last choice. (a, b), in this question, means the domain or range is from a to b, exclusive. When you use ∞, you would always use the exclusive.

4. See if you can find "like-terms" in the expression and
WITCHER [35]

Answer:

After finding like terms and solving, we get \mathbf{3x^2+3x+16}

Step-by-step explanation:

We need to find like terms and simplify the expression 4- 2x + x^2 + 5x + 12 + 2x^2

Like terms: The terms who have same variable and exponent are called like terms.

So, Combining like terms and solving:

4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16

So, after finding like terms and solving, we get \mathbf{3x^2+3x+16}

<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2

I have solved using +5x, but if the term is -5x then the solution will be:

4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16

So, the answer will be: \mathbf{3x^2-7x+16}

In the following system of equations, what would you do to eliminate x? 2x + 4y = 10 x - 3y = 12
Anvisha [2.4K]
2x +4y =10x-3y =12

2x +4y =12 -----eq. 1

10x-3y =12 -------eq.2


2x =12 -4y [using eq. 1]
x = (12-4y)/ 2
= 6 -2y

Now, substitute the value of x in eq. 2
10 (6-2y)-3y =10
60 -20y -3y =10
-23 y = 10 -60
y = -50 / -23
y = 50/23


Now, substitute this value of y in any equations given above

10 x-3 (50/23) =12
10x - (150/23)= 12
x= 426/230
