That would be negative 1 for your answer to 8 - 9

there are 13 hearts in a deck so that would be

$\frac{13}{52} = \frac{1}{4}$

so if we draw for a second time that would be

$\frac{12}{51} = \frac{4}{17}$

hopefully this helps

Factor the expression 12x^2 +7x+1

Leona [35]

Answer:

$\boxed{\textsf{ The factorised form is \textbf{(4x+1)(3x+1)}.}}$

Step-by-step explanation:

A quadratic polynomial is given to us and we need to find its factorised form . The given quadratic polynomial is ,

$\sf\implies p(x)= 12x^2+7x+1$

And this equation is similar to the equation in ax² + bx + c form . So in order to factorise it .

Step 1: Multiply the coefficient of x² with the constant term .

Here the coefficient of x² is 12 and the constant term is 1 . So on multiplying them we get 12*1= 12 .

Step 2: Look out for the possible factors of the number .

Here the obtained number is 12 . So the possible factors of 12 is

1 *12
-1*-12
2*6
-2*-6
4*3
-4*-3

Step3: Choose the factor whose sum is equal to the coefficient of the middle term .

Here we can see that the middle term is 7 . And the sum of 4 and 3 is equal to 7 . Hence here we will break 7x as 4x + 3x .

Step 4: After proper arrangements take out the common term and then factorise.

After suitable rearrangment we get ,

$\sf\implies p(x)= 12x^2+4x+3x+1 \\\\\sf\implies p(x)= 4x(3x+1)+1(3x+1) \\\\\implies\boxed{\red{\sf p(x)= (4x+1)(3x+1)}}$

Please help me i’ll appreciate it

Answer:

Step-by-step explanation:

You can pick a point, such as the vertex at (2, -3) on f(x) and see which of the transformations gives you a point on the graph of g(x).

You will find that g(x) represents a vertical scaling by a factor of 1/3, so ...

g(x) = 1/3·f(x)

The point (2, -3) on f(x) corresponds to the point (2, -1) on g(x).
