Answer:
y=1.5x-8
Step-by-step explanation:
this is because you first need to fond the change in the x axis and the y axis which will give you the gradient. Then you will have to substitute any co-ordinate and gives you c.(Y=mx+c) is the equation of a straight line.
You can make it easier by replacing x^n with another variable, factoring, then putting x^n back in the end.
Using exponent and algebra rules, rewrite x^2n - 2x^n + 1 as
(x^n)^2 - (2 x x^2) + 1
Then, let x^n = m.
m^2 - 2m + 1
Now factor that: (m - 1)^2
And now put x^n back: (x^n - 1)^2
Answer:
Price of CD player = $96
Step-by-step explanation:
Given:
Sales tax = 5%
Amount of sales tax = $4.80
Find:
Price of CD player
Computation:
Price of CD player = Amount of sales tax / Sales tax
Price of CD player = 4.8 / 5%
Price of CD player = $96
Answer:38
Step-by-step explanation:if you take 24 and subtract the five she added, it gives you 19 and since she divided it by two you would multiply it by two to get the original number she was thinking of
