To add 13% vat we can multiply by (100%+13%) = 113% = 1.13
To remove 13% vat divide by 1.13
339 / 1.13 = 300 the discounted price.
The amount of discount = 400 - 300 = 100
Discount rate = 100 / 400 = 1/4 = 25%
We can put in 6 - 2x for y:
2x + y = 6
2x +(6 - 2x) = 6
2x + 6 - 2x = 6
6 = 6
Since this statement is true:
x and y are all real numbers.
Hope this helps!
X^2 + y^2 = radius^2
Is that what your adking for? This is for a circle around the origin.
Answer:
x= -6
v= 1
v= 2
Step-by-step explanation:
-3= x+7-4, combine like terms by subtracting seven from four
-3= x+3, subtract three from both sides
-6= x
8v-3+3v= 8, combine like terms by adding 8v and 3v
11v-3= 8, add three to both sides
11v= 11, divide both sides by 11
v=1
-v+3v=4, combine like terms by adding -v and -3v
2v= 4, divide both sides by 2
v= 2
Answer:
y=(x^2 -2x-3)/3
Step-by-step explanation:
f(x)= √3x+4 -1
x=√3y+4 -1
(x+1)^2=(√3y+4)^2
3y+4=x^2 +2x+1
3y=x^2 +2x-3
y=(x^2 +2x-3)/3
