Answer:
The two options are:
-3x² - 11x + 11 and 5x² + 3x - 7
Step-by-step explanation:
When two polynomials are subtracted the difference is
-4x² - 7x + 9
One of the polynomials is
x² - 4x + 2
To get the second polynomial, we an either add x² - 4x + 2 to -4x² - 7x + 9 or subtract -4x² - 7x + 9 from x² - 4x + 2
First Option:
(x² - 4x + 2) + (-4x² - 7x + 9)
= x² - 4x + 2 - 4x² - 7x + 9
= x² - 4x² - 4x - 7x + 2 + 9
= -3x² - 11x + 11
Secons Option:
(x² - 4x + 2) - (-4x² - 7x + 9)
= x² - 4x + 2 + 4x² + 7x - 9
= x² + 4x² - 4x + 7x + 2 - 9
= 5x² + 3x - 7
Therefore, the two options are:
-3x² - 11x + 11 and 5x² + 3x - 7
Answer:
x = 3 days y = $7
Step-by-step explanation:
Answer:$5408
Step-by-step explanation:
The first company offers a straight commission of 5% of the sales. This means the salary or income is 5% of sales made.
The second company offers a salary of $260 per week plus 4% of the sales. This means salary or income
= $260 +4% of 260
= 260 + (4/100)×260
= 260 +(0.04×260)
=260+10.4 = $270.4
Let x = the amount of sales you would have to sell in a week in order for the straight commission offer to be at least as good
5% of x should be greater than or equal to $270.4
0.05x = 270.4
x = 270.4/0.05 =$5408
The sales should be greater than or equal to $5408
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1
Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63
Equation of our hyperbola will be:
x²/81 - y²/63 = 1
