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
-adxy +bcxy -bd
But, ac = 18, ad=bc, bd = 50
18
-xy(bc -ad) - 50
since bc = ad, the coefficient of xy = 0

Answer:
the arc length is 555.17 cm
Step-by-step explanation:
The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·
You want to find the distance the golf club travels when the golfer swings the club.
First you need to subtract 25° from 360°
360° - 25° = 335°
now you need to convert 335° into radians
radians = degrees ·
radians = 335° · you multiply 335° by
radians = 335/180 then you simplify
radians = 67/36
335° = 67
/36
Now we plug everything we know into the equation s = rΘ
s = rΘ
s = 95 (67
/36) first multiply 67 by 3.14
s = 95 (210.38/36) divide 210.38 by 36
s = 95 (5.843888889) and multiply 95 by 5.843888889
s = 555.1694444 *remember to simplify to the nearest hundredth
s = 555.17 cm
hope this helps! if u have any questions, let me know!
4. It cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.
5. The relationship in Tuesday's table can be described by a constant unit rate.
<h3>What is a Constant Unit rate Relationship?</h3>
A constant unit rate relationship can be described as a relationship between two input and output variables, x and y, in such a way that, k = y/x. "k" is the constant of proportionality of the relationship or the unit rate between the two variables.
4. We have the following:
5/20 = 1/4
10/40 = 1/4
12/60 = 1/5
14/80 = 7/40
16/100 = 4/25
Thus, this cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.
5. 4/20 = 1/5
8/40 = 1/5
12/60 = 1/5
16/80 = 1/5
20/100 = 1/5
Thus, the value of k is the same across all table values, therefore, the relationship in Tuesday's table can be described by a constant unit rate.
