use the distributive property to remove parentheses. Simplify your answer as much as possible. 1/2(4y+7)

Anna007 [38]

1/2(4y+7)

Use the distributive property. a(b+c)= ab+ac

1/2*4y= 2y

1/2*7= 3.5

2y+3.5 <---- simplified expression

I hope this helps!

PLEASE HELP<br>L has y-intercept (0,5) and is perpendicular to the line with equation y=1/3x+1

marin [14]

Answer:

y=-3x+5

Explanation:

Given a line L such that:

• L has y-intercept (0,5); and

• L is perpendicular to the line with equation y=(1/3)x+1.

We want to find the equation of the line in the slope-intercept form.

The slope-intercept form of the equation of a straight line is given as:

$\begin{equation} y=mx+b\text{ where }\begin{cases}m={slope} \\ b={y-intercept}\end{cases} \end{equation}$

Comparing the given line with the form above:

$y=\frac{1}{3}x+1\implies Slope,m=\frac{1}{3}$

Next, we find the slope of the perpendicular line L.

• Two lines are perpendicular if the product of their slopes is -1.

Let the slope of L = m1.

Since L and y=(1/3)x+1 are perpendicular, therefore:

$\begin{gathered} m_1\times\frac{1}{3}=-1 \\ \implies Slope\text{ of line L}=-3 \end{gathered}$

The y-intercept of L is at (0,5), therefore:

$y-intercept,b=5$

Substitute the slope, m=-3, and y-intercept, b=5 into the slope-intercept form.

$\begin{gathered} y=mx+b \\ y=-3x+5 \end{gathered}$

The equation of line L is:

$y=-3x+5$

Lyrx [107]

Answer:

in a multicriteria decision problem the decision maker must evaluate each alternative with respect to each criterion.

Step-by-step explanation:

Multiple-criteria decision-making (MCDM) is a sub-discipline of operations research that explicitly evaluates multiple conflicting criteria in decision making (both in daily life and in settings such as business, government and medicine e.t.c)

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?

lesya [120]

Let us solve the inequality first

$2(x-1)\ge -12$

Dividing through by 2 gives

$(x-1)\ge -6$

Grouping like terms gives

$x\ge -6+1$

This implies that;

$x\ge -5$

This corresponds to option A in words

If we rewrite as

$-5\le x$

it will correspond to option C in words

Representing on diagram corresponds to option D (See attachment)

All are correct ways to represent the solution except B.

The correct answer is option B
