The value of the coefficient of xy is 0.

<h3>What is an algebraic expression?</h3>

It is an expression made of numbers and letters where the numbers are called coefficient.

Analysis:

(ax+by)(cx-dy)

ac $x^{2}$ -adxy +bcxy -bd $y^{2}$

But, ac = 18, ad=bc, bd = 50

18 $x^{2}$ -xy(bc -ad) - 50 $y^{2}$

since bc = ad, the coefficient of xy = 0

I need assistance :D, Instructions: Using the image, find the distance between the points given on the graph.

kogti [31]

Answer:

Step-by-step explanation:

You have to use the distance formula to find that distance. The formula is:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

Let's call the first point x1, y1 (4, -1) and the second point x2, y2 (0, -2). Plugging into our formula then gives us this:

$d=\sqrt{ (0-4)^2+(-2-(-1))^2}$

which simplifies to

$d=\sqrt{(-4)^2+(-1)^2}$ which is

$d=\sqrt{17}$ ≈ 4.123 units

Suppose the average yearly salary of an individual whose final degree is master's is $40 thousand less than twice that of an ind

Lostsunrise [7]

Answer:

<h2>x=50000 dollars ( the average salary of bachelor degree)</h2><h2>the average salary of Masters degree = 2x-40000</h2><h2>2(50000)-40000=60000 dollars</h2><h2></h2><h2>step by step explanation :</h2>

let x be the salary of individual with bachelor degree

Then the average salary of individual with Masters degree is:

(2x-40000)

the combined of two salaries is 110000:

x+(2x-40000)=110000

3x-40000=110000

3x=110000+40000

x=150000/3

<h2>x=50000 dollars ( the average salary of bachelor degree)</h2><h2>the average salary of Masters degree = 2x-40000</h2><h2>2(50000)-40000=60000 dollars</h2>

In the diagram below of parallelogram ABCD with diagonals AC and BD, m∠1=45° and m∠DCB=120°.Whatisthemeasureof∠2?

bixtya [17]

Answer:

15degrees

Step-by-step explanation:

From the given diagram

<1+<2 + <DCB = 180

<1+<2+120 = 180

<1+<2 = 180 - 120

<1+<2 = 60

<2 = 60 - <1

<2 = 60 - 45

<2 = 15degrees

Hence the measure <2 is 15degree
