Hello!
<span>The constant of variation is xy. XY=23. If X=7 then Y=23/7.
</span>
So as we can see, the stated inverse variation can be represented as the equation y = k/x. ===> k = 23 & x = 7 ⇒ y = 23/7. <====

The is answer E, you have to search for -3 in the x line than search for -2 in the y line
Answer:
General equation of line :
--1
Where m is the slope or unit rate
Table 1)
p d
1 3
2 6
4 12
d = Number of dollars (i.e.y axis)
p = number of pound(i.e. x axis)
First find the slope
First calculate the slope of given points
---A


Substitute values in A
Thus the unit rate is 3 dollars per pound.
So, It matches the box 1 (Refer the attached figure)
Equation 1 : 

Since p is the x coordinate and d is the y coordinate
On Comparing with 1

Thus the unit rate is
dollars per pound
So, It matches the box 2 (Refer the attached figure)
Equation 2 : 

Since p is the x coordinate and d is the y coordinate
On Comparing with 1

Thus the unit rate is 9 dollars per pound
So, It matches the box 3 (Refer the attached figure)
Table 2)
p d
1/9 1
1 9
2 18
d = Number of dollars (i.e.y axis)
p = number of pound(i.e. x axis)


Substitute values in A
Thus the unit rate is 9 dollars per pound
So, It matches the box 3 (Refer the attached figure)
Answer:
$2
Step-by-step explanation:
$18-$4=$14
$14/7=$2
So first, you want to find that top angle Y. You can do this by subracting 115 from 180 giving you 65. Next I started searching for K. After inserting numerous numbers into the equation I found that 10 gave me the answer as shown below.
180 - 115 = 65
4(10) + 5 = 45
6(10) + 10 = 70
70 + 65 + 45 = 180
Add those together and you get 180 degrees, which is always the total number of degrees for a triangle. So your answer is 10.
Hope this helps! <3
