\boxed{x_{1}=3}\\ \\ \boxed{x_{2}=-0.5}

<h2>Explanation:</h2>

Hello! Recall that if you want to get correct and good answers, you need to post your question in a clear way. However, I'll try to help you, so let's get started:

The quadratic equation isn't clear, so let's assume that equation is as follows:

2x^{2}-5x-3=0

A quadratic equation is given by the form:

ax^2+bx+c=0

To find the solutions, we can apply the quadratic formula:

x_{12}=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \\ Here: \\ \\ a=2 \\ b=-5 \\ c=-3 \\ \\ \\ Substituting: \\ \\ x_{12}=\frac{-(-5) \pm \sqrt{(-5)^2-4(2)(-3)}}{2(2)} \\ \\ x_{12}=\frac{5 \pm \sqrt{25+24}}{4} \\ \\ Finally, \ we \ get \ two \ solutions: \\ \\ x_{1}=\frac{5+ \sqrt{25+24}}{4}=\frac{12}{4} \therefore \boxed{x_{1}=3} \\ \\ \\ x_{2}=\frac{5-\sqrt{25+24}}{4}=-\frac{2}{4} \therefore \boxed{x_{2}=-0.5}

A grocery store sells avocados for $1.25 each. The graph shows the cost for different numbers of avocados.
Aleksandr [31]
I don’t know if this is right or not so, sorry if it’s wrong ;-;

1,2,3,4,5 = independent

c=1.25a = neither

$1.25, $2.50, $3.75, $5.00, $6.25 = dependent

Number of avocados = independent

Cost of avocados = dependent

If this is right then I’ll put the explanation in the comments, again sorry if it isn’t.

The local bakery applies a 155% markup on all baked goods. If it costs them $3.50 to make a batch of cookies, at what price do t
natka813 [3]

The price charged for the batch of cookies is $8.925

Step-by-step explanation:

Marked price refers to the price at which an establishment offers to sale a product. For-profits to occur, marked price is always more than cost price (cost of producing the item)

Here the local bakery has marked up the price by 155%. This means that the local bakery has increased the marked price by 155% above the cost price accrued to them.

The cost price of the cookies= $ 3.5

Hence the increased marked price= (155/100) *3.5

Increased marked price= $ 5.425

Hence the charge customers need to pay for the cookies= increased marked price + cost price

Charge = $5.425+ $3.5= $8.925

the price charged for the batch of cookies is $8.925
