The slope formula is
![\frac{Y2-Y1}{X2-X1}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7BY2-Y1%7D%7BX2-X1%7D)
. For the two points,
![(x,y)](https://tex.z-dn.net/?f=%28x%2Cy%29%20)
. You can pick any of the Y and X from these two points, but only once.
![\frac{9-15}{9-12}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B9-15%7D%7B9-12%7D)
=
![\frac{-6}{-3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-6%7D%7B-3%7D)
= 2 or
![\frac{15-9}{12-9}](https://tex.z-dn.net/?f=%20%5Cfrac%7B15-9%7D%7B12-9%7D)
=
![\frac{6}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B3%7D)
= 2 and both will equal to. The answer for the slope is 2.
Answer:
The answers are :
1. 5%.
2. 467.50 DKK.
Step-by-step explanation:
Given:
Discount on Monday of a good at 10 percent.
Increase discount on Friday would be 15 percent.
1. Difference between the percentage =
.
So, the percentage increase in discount is
.
2. First, the actual price means the price without discount should be calculated.
So,let the actual price be
:
According to question,
of![x=495 DKK](https://tex.z-dn.net/?f=x%3D495%20DKK)
=![\frac{90x}{100}=495](https://tex.z-dn.net/?f=%5Cfrac%7B90x%7D%7B100%7D%3D495)
Multiplying both sides by 100
![\frac{90x}{100}\times100=495\times100](https://tex.z-dn.net/?f=%5Cfrac%7B90x%7D%7B100%7D%5Ctimes100%3D495%5Ctimes100)
=![90x=495](https://tex.z-dn.net/?f=90x%3D495)
Dividing both sides by 90
![\frac{90x}{90} =\frac{49500}{90}](https://tex.z-dn.net/?f=%5Cfrac%7B90x%7D%7B90%7D%20%3D%5Cfrac%7B49500%7D%7B90%7D)
=
.
And, now the price after the announcement of the
discount
of ![550](https://tex.z-dn.net/?f=550)
=
% of ![550](https://tex.z-dn.net/?f=550)
=![\frac{85}{100}\times550](https://tex.z-dn.net/?f=%5Cfrac%7B85%7D%7B100%7D%5Ctimes550)
=![\frac{46750}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B46750%7D%7B100%7D)
=
.
So, the price after the announcement of the
percent discount is
DKK.
Therefore, the answers are :
1. 5%.
2. 467.50 DKK.
I don’t know the answer for sure but i do know for surface area you multiply all the sides together so maybe that will help you. (you would count how many units they go over for each line.)
Answer:
Smaller=18 degrees; larger= 162 degrees
Step-by-step explanation:
ok so first supplementary angles mean that the two angles added together will equal 180 degrees.
so 1x + 9x = 180 (combine like terms)
10x=180 (divide each side by 10)
x=18
so the smaller angle is 18 because its only 1x, and the larger angle is 162 because 18x9=162
check: 18 + 162 = 180
