Which expression represents the word phrase 6 decreased by one-third of a number? a. 6+13−x b. 6+13+x c. 13⋅x−6 d. 6−13⋅x

1 answer:

6 0

The answer is D but it is written
$6 - \frac{1}{3} x$
The word decreased means to subtract but as the expression states 1/3 of a number, 6 is subtracted by 1/3 times whatever number X represents.

The simplified form of given expression is $2x^3-5x^2-17x+20$

Solution:

Given that we have to simplify the expression

Given expression is:

$(x-4)(2x^2+3x-5)$

We can simplify the expression by multiplying each term in first bracket with each term term in second bracket

$\rightarrow (x-4)(2x^2+3x-5)$

$\rightarrow (x)(2x^2)+(x)(3x)+(x)(-5)-4(2x^2)-4(3x)-4(-5)$

Simplify the above expression by multiplying the numbers in each term and adding the coefficients of like variables in each term

$\rightarrow 2x^3+3x^2-5x-8x^2-12x+20$

Combine the like terms

$\rightarrow 2x^3+3x^2-8x^2-5x-12x+20$

$\rightarrow 2x^3-5x^2-17x+20$

Thus the expression is simplified

A walking path across a park is represented by the equation y=-4x+10. A new path will be built perpendicular to this path. The p

Lera25 [3.4K]

Given:

The equation of a line is

$y=-4x+10$

A perpendicular line on the given line passes through the point (4,-6).

To find:

The equation of the perpendicular line.

Solution:

We have,

$y=-4x+10$

On comparing this equation with slope intercept form $y=mx+b$ , we get

$m=-4$

So, the slope of the given line is -4.

We know that the product of slopes of two perpendicular lines is always -1.

$m\times m_1=-1$

$(-4)\times m_1=-1$

$m_1=\dfrac{-1}{-4}$

$m_1=\dfrac{1}{4}$

The slope of the required line is $\dfrac{1}{4}$ and it passes through the point (4,-6). So, the equation of the line is

$y-y_1=m_1(x-x_1)$

$y-(-6)=\dfrac{1}{4}(x-4)$

$y+6=\dfrac{1}{4}x-1$

$y=\dfrac{1}{4}x-1-6$

$y=\dfrac{1}{4}x-7$

Therefore, the correct option is B.
