hi!
its not a function since it has a =5
this is an equation
Answer:
Step-by-step explanation:
Generally equation of a line is given as
y=mx+c
Then given the point (x, y)=(0,2)
Therefore x=0 and y=2
y=mx+c
2=m×0+c
2=0+c
Then, c=2
Then intercept is 2
Also given the point (x, y)=(3,4)
x=3 and y=4 and c=2
y=mx+c
4=m×3+2
4=3m+2
4-2=3m
2=3m
Then, m=2/3
Then, the slope of the graph is 2/3
y=mx+c
Now, m=2/3 and c=2
The general equation of the line becomes
y=2/3x+2
Multiply through by 3
3y=2x+6
Then this is the equation of the line
Answer:
(6x^2)(x^4 +x^2 + 1)
Step-by-step explanation:
6x^6 + 6x^4 + 6x^2
split it up into parts
6x^6 = (6x^2) * x^4
6x^4 = (6x^2) * x^2
6x^2 = (6x^2) * 1
so you can take out 6x^2 to get
(6x^2)(x^4 +x^2 + 1)
Vertex = (1/2,5/2) x= 1 + or - square root of 5-2y all over 2
Answer:
let's say the item bought costs £20
sales tax first
20/100 X 7.5 = 1.50. 20 + 1.50 = 21.50
21.50/100 X 20 = 4.30
21.50 - 4.30 = £17.20
discount first
20/100 X 20 = 4
20 - 4 = 16
16/100 X 7.5 = 1.20
16 + 1.20 = £17.20
it wouldn't matter
