Answer:

Answer is imaginary roots

Step-by-step explanation:

$({4x}^{3} - {5x}^{2} + 3x) + ( - {2x}^{3} - {x}^{2} + 6x) \\ 2 {x}^{3} - 6 {x}^{2} + 9x = 0 \\ dividing \: by \: x \\ 2 {x}^{2} - 6x + 9 = 0 \\ dividin g\: by \: 2 \\ {x}^{2} - 3x + \frac{9}{2} = 0 \\ shifting \: the \: constant \: term \: on \: right \: side \\ {x}^{2} - 3x = - \frac{9}{2} \\ adding \: \frac{1}{2} \times (coefficient \: of \: x) \: whole \: square \\$

On solving the above mentioned equation we get some imaginary values.

 HAVE A NICE DAY!

If there are 35 yellow books in the bookcase, then how many green books are in the bookcase

alukav5142 [94]

ANSWER

D. 14

EXPLANATION

The ratio of the books in the book case are:

Red:Yellow:Green=3:5:2

The number of yellow books in the book case is 35.

If 5 corresponds to 35, then 2 green books will correspond to a less number of books,

By proportion, because it is going to be less more will divide.

The number of green books in the book case is

$= \frac{35 \times 2}{5}$

$= 7 \times 2 = 14$

What is an equation in slope-intercept form for the line that passes through the points (1 -3) and (3 1)

Bas_tet [7]

Answer:
$y = 2x - 5$

Explanation:

Slope-intercept form formula:
$y = mx + b$
For this formula we need the slope to find the slope use the slope formula:
$\frac{y_{2} - y}{x_{2} - x}$
Plug in the two points (1,-3) and (3,1)
$\frac{1 - - 3}{3 - 1}$
$\frac{4}{2}$
=2
the slope is 2

Now use the slope-interpect formula and plug in the slope (m)
$y = 2x + b$
plug in one point I'll use (3,1)
$1 = 2(3) + b$
1 = 6 +b
1-6=6-6+b
-5 = b

The equation would be:
$y = 2x - 5$
