1. A quadratic equation has the following form: ax²+bx+c.
2. The leading coefficient is the number that is attached to the variable with the highest exponent. Then, the "a" is the leading coefficient of the quadratic equation.
3. The problem says that the leading coefficient is 1 (a=1) and the roots of the quadratic equation are 5 and -3. Then, you have:
(x-5)(x+3)=0
4. When you apply the distributive property, you obtain:
x²+3x-5x-15=0
x²-2x-15=0
5. Therefore, the answer is:
x²-2x-15=0
Answer:
The total earning of commission on sales of 85, 000 will be:
Step-by-step explanation:
- Total sales earning = 85,000
As salesperson earns 5% commission the first 70,000.
As the salesperson earns 7% commission on the sales over 70,000.
As 15000 is the sales earning on which he will get commission 7%.
Because
So the 7% earning of salesperson will on 15000 will be:
Therefore, the total earning of commission on sales of 85, 000 will be:
Since the rate of the other store is not given, let us just get the sales price of the skirt Dima bought from the discount store.
Original price : $54
Discount rate : 30%
$54 x 30% = $16.20 value of the discount
$54 - 16.20 = $37.80 discounted price.
Since Dima's friend told her she could have had a better deal at a different store, this means that the discount rate is higher than 30%. Let us assume that the discount is 35%
$54 x 35% = $18.90 value of the discount
$54 - 18.90 = $35.10 discounted price.
Discount store: $37.80
Different store: $35.10
Different store sales price is cheaper by $2.70
