Answer: 0=5.00
5=6.25
8=7.50
10=8.75
30=10.00
Step-by-step explanation:
Y =mx+b
We first find the zeros of the function , the zeros of the function are those at which points the graph of the function crosses or touches the x axis
here we can see in the graph that graph crosses the x axis at two points , 1 and 7
So the zeros of the function are
x=1 and x=7
It means the factor are
(x-1) and (x-7)
So the factorization is given by
(x-1)(x-7)
Let n = the number of points
(x-1) + ... (x-x)
The last term will always be 0, when you reach that, stop.
ex. 1pt: 1-1=0
2pt: (2-1) + (2-2) = 1
3pt: (3-1) + (3-2) + (3-3) = 3
We are given that:
i- The store is having 20% off sale
ii- Trina has a 10% coupon
Therefore, Trina will be having a discount = 20 + 10 = 30% of the bike's price
This means that:
Trina will pay 100% - 30% = 70% of the price
We are given that:
The original price of the bike = <span>$89.75
We now know that:
Trina will pay 70% of its price
Therefore:
Final price = 70% * </span>89.75 = 0.7 * <span>89.75
Final price = $62.825
Hope this helps :)</span>
