Answer:
Explainion are shown in pictures above
The condition that must not be met before usage us that the coefficient of the x²-term must be positive.
<h3>Equations of quadratic function</h3>
The standard quadratic function is given as;
ax²+bx + c = 0
From the equation shown above, the leading degree of the equation is 2. The following are condition that must be met before you can use
the quadratic formula to find the solutions of an equation.
- There can be no term whose degree is higher than 2.
- The coefficient of the x²-term can't be zero.
The condition that must not be met before usage us that the coefficient of the x²-term must be positive.

Answer:
Step-by-step explanation:
We know that she will be selling bracelets for $2 each and earrings for $3 each. That means we will have 2x+3y, where x is the number of bracelets she sells and y is the number of earrings she sells. Then we will have because she wants to sell <u>at least $60</u> worth of earrings and bracelets. That means the amount she makes from bracelets and earrings combined has to equal 60 or more, thus we use the greater than or equal to sign.
Now we have , where x is still the number of bracelets sold. She said she will sell <u>more than 10</u>, which means we will just have . If she said she wanted to sell <u>at least 10</u>, then it would be .
Therefore the system of inequalities is:
