katovenus [111]

Answer:

maximum 5 CDs

Step-by-step explanation:

Let Mitchell can order a maximum of x CDs

It has been given that each CD costs $15.99, and shipping for the entire order is $9.99.

Thus, we have the total cost for x CDs

$15.99x+9.99$

Now, Mitchell has no more than $100 to spend. It means

$15.99x+9.99$

Subtract 9.99 to both sides

$15.99x$

Divide both sides by 15.99

$x$

Hence, Mitchell can order maximum 5 CDs

X2 + 45x = -200 Using the quadratic formual and the discirimnat

dybincka [34]

Answer:

Positive discriminant = 2 real solution

x= -5,-40

Step-by-step explanation:

The discriminant is used to see how many solutions an equation has. If it is negative, the equation has no real solutions, if =0 the equation has 1, and if it is positive, the equation has two real solutions.

The discriminant is the part of the quadratic formula inside the square root:

$b^{2}-4ac$

Every quadratic formula has the structure:

$ax^{2} +bx+c=0$

So first, in order to meet this structure we need to add 200 to both sides so the equation is equal to 0. This gives us:

$x^{2} +45x+200=0$

Our a=1, b=45 and c=200

Now we can substitute these values into the discriminant:

$(45)^{2} -4(1)(200)$

Solve:

$2025-800=1225$

The discriminant is a positive number which means this equation will have 2 real solution. Now we just need to plug in our values into the quadratic formula to solve this equation. Quadratic formula:

$x=\frac{-+/-\sqrt{b^{2}-4ac} }{2a} \\x=\frac{-45+/-\sqrt{1225} }{2}$

(Same discriminant value)

$x=\frac{-45+/-35}{2}$

Now to find the two solutions, we use both signs in the equation. Solution 1:

$x=\frac{-45+35}{2}$

$x=\frac{-10}{2}=-5$

Our first solution is -5, now for the second:

$x=\frac{-45-35}{2}\\\\ x=\frac{-80}{2}=-40$

The two solution to this equation are -5 and -40.

Hope this helped!

A movie theater sells adult tickets for $6 each. Senior citizens receive a discount of $3. One evening the theater sold 400 tick

Andrej [43]

Answer:

Number of senior citizen tickets sold= 110

Number of adults tickets sold= 290

Step-by-step explanation:

First, we need to establish a system of equations:

x= number of adults tickets

y= number of senior citizen tickets

x + y= 400

6x + 3y= 2,070

Now, we isolate x in one equation and substitute the value in the other:

x= 400 - y

6*(400 - y) + 3y = 2,070

2,400 - 6y + 3y = 2,070

330 = 3y

110 = y

Number of senior citizen tickets sold= 110

Number of adults tickets sold= 290

Prove:

290 + 110= 400

6*290 + 3*110= 2,070

Answer:

Step 6 is done by Additive Property of Equality, also known as Compatibility of Equality with Addition, which is defined by the following expression:

$a = b \to a + c = b + c$ , $\forall\,a,b, c\,\in \,\mathbb{R}$

Step-by-step explanation:

Step 6 is done by Additive Property of Equality, also known as Compatibility of Equality with Addition, which is defined by the following expression:

$a = b \to a + c = b + c$ , $\forall\,a,b, c\,\in \,\mathbb{R}$

1) $(7\cdot x - 3) + 3 = (2\cdot x + 7) + 3$ Associative property/Compatibility with addition

2) $7\cdot x + [3 + (-3)] = 2\cdot x + (7 + 3)$ Associative and commutative properties/Definition of subtraction

3) $7\cdot x + 0 = 2\cdot x + 10$ Existence of the additive inverse/Definition of addition

4) $7\cdot x = 2\cdot x + 10$ Modulative property/Result
