Edan buys 3 tickets to a concert. When the delivery charge of $7.75 per order is added to the cost of the tickets, the total cost is $70.75. A) Create an algebraic equation for this problem. Use the equation to determine the cost of each ticket. Verify your solution. B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan? C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she wants to make a profit of at least $100?

Answer:

55mg

Step-by-step explanation:

In order to calculate the total number of vitamin mg are in the drink we first need to turn the percentage of vitamin mg in the drink into a decimal. We do this by dividing the percentage by 100 like so...

110 / 100 = 1.1

Now that we have the decimal value of the percentage we simply multiply it by the recommended daily allowance​ (RDA) for this vitamin.

1.1 * 50mg = 55mg

Finally, we can see that the new health drink contains 55mg of this vitamin.

The slopes and y-intercepts of the two equations are

✔ different

, so this system has

✔ exactly one solution

Step-by-step explanation: i got it wrong so you can get it right :0

The larger number is 8 while the smaller number is 2. The slope and y-intercept of the equations y = –x + 10 and y = 4x are different so the system has exactly one solution.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

As per the given system of equations,

x + y = 10, y = 4x

The slope and y-intercept of (x + y = 10 ⇒ y = -x + 10) will be -1 and 10.

The slope and y-intercept of y = 4x will be 4 and 0.

Substitute, y = 4x into x + y = 10

x + 4x = 10

5x = 10

x = 2

And, y = 4 x 2 = 8

Hence "The larger number is 8 while the smaller number is 2. The slope and y-intercept of the equations y = –x + 10 and y = 4x are different so the system has exactly one solution".

Answer: 35 cupcakes

Step-by-step explanation: If a bakery sells 5 cupcakes for every 3 cupcakes, then use this ratio of (5 : 3). Now, that we know that 21 cookies were sold on Saturday, divide 21 by 3, which equals to 7. Lastly, multiply 5 x 7, which gives us a final result of 35 cupcakes.

Extra Work: You don’t have to do this, but the ratio would be (35 : 21), as a final result.

Answer:

(29/8, -3)

Step-by-step explanation:

To work out any midpoint on a line, you use the two coordinates and find the middle of each x and y. So:

(⁽ˣ¹ ⁺ ˣ²⁾/₂ , ⁽ ʸ¹ ⁺ ʸ²⁾⁄₂)

We simply plug in our values here to solve. See attached image for solving steps.

Answer:

The function rule is: [tex]y = -3x-5[/tex]

Step-by-step explanation:

Using the given input/output values, we can take two pairs of input-output values for finding the rule.

The function is a linear function as the input and output are changing linearly.

Required pairs are:

(1,-8)  and (2, -11)

The general rule for linear function is:

[tex]y = mx+b[/tex]

m is the slope of the function calculated using the formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Putting the values

[tex]m = \frac{-11+8}{2-1}\\m = \frac{-3}{1}\\m = -3[/tex]

Putting in equation

[tex]y = -3x+b[/tex]

To find the value of b, putting (1,-8) in the equation

[tex]-8 = -3(1) +b\\-8 = -3+b\\-8+3 = b\\b = -5[/tex]

Putting the values

[tex]y = -3x-5[/tex]

Hence,

The function rule is: [tex]y = -3x-5[/tex]

Answer:

65.09

Step-by-step explanation:

61×6.7%＝4.087

4.087+61＝65.087

65.087≈65.09

Answer:

1 solution.

Step-by-step explanation:

Expanding the given linear equation.

[tex]6(3x^2+4)10 = 1/2(4x+16)\\\hfill\\180x^2+240=2x+8\\\hfill\\\\180x^2-2x+232=0[/tex]

Divide everything by 2.

[tex]90x^2-x+116=0[/tex]

Here, you would use the quadratic formula and see that there is only one solution, however, it is not a real solution.
