Hello!!!

The Graph's Answer is below

<u>Nicole's Pattern                   Ian's Pattern               Coordinate's Plane               </u>

 1                                                 0                                   ( 1,0)

5                                                 1                                   (5,1)

17                                                3                                 (17,3)    

53                                               7                                (53,7)    

161                                               15                              (161,15)

In order to get these answers, you start with 1 one Nicole's equation, and mutliply by 3, which gets you three. You then add two, which gets you five, after this, you continue to add Nicole's answer by three, then add five.For Ian's answer,you start with 0,then you add 1/2, which gives you .5 After you have this .5 you multiply by 2,which gives you one whole, you continue to add a half and mutliply by 2 for each answer. Nicole's answer is X,which means it is used first in our parentheses ( ),while ian's is Y and is used second.

I HOPE THIS HELPS! Good luck on your assignment and let me know if you need help with anything else <3!

Formulate the situation as a system of two linear equations in two variables. Be sure to state clearly the meaning of your x- an
adoni [48]

Answer: 1000 hot dogs and and 1600 sodas were sold.

Step-by-step explanation:

Let x be the number of hot dogs and y be the number of sodas.

Given : The concession stand at an ice hockey rink had receipts of $6200 from selling a total of 2600 sodas and hot dogs.

Each soda sold for $2 and each hot dog sold for $3 .

Then, we have the following system of two linear equations:-

x+y=2600-----------(1)\\\\3x+2y=6200-----------(2)

Multiplying 2 on both sides of (1), we get

2x+2y=5200------------(3)

Now, Eliminate equation (3) from equation (2), we get

x=1000

Put x=1000 in (1), we get

1000+y=2600\\\\\Rightarrow\ y=2600-1000=1600

Hence, 1000 hot dogs and and 1600 sodas were sold.

Complete the square to find the minimum value of the expression 4x2 + 8x + 23.
Tcecarenko [31]
So you need to come up with a perfect square that works for the x coefficients.
like.. (2x + 2)^2
(2x+2)(2x+2) = 4x^2 + 8x + 4
Compare this to the equation given. Our perfect square has +4 instead of +23. The difference is: 23 - 4 = 19

I'm going to assume the given equation equals zero..

So, If we add subtract 19 from both sides of the equation we get the perfect square.

4x^2 + 8x + 23 - 19 = 0 - 19
4x^2 + 8x + 4 = - 19
complete the square and move 19 over..
(2x+2)^2 + 19 = 0
factor the 2 out becomes 2^2 = 4
ANSWER: 4(x+1)^2 + 19 = 0

for a short cut, the standard equation
ax^2 + bx + c = 0 becomes a(x - h)^2 + k = 0
Where "a, b, c" are the same and ..
h = -b/(2a)
k = c - b^2/(4a)

Vertex = (h, k)
this will be a minimum point when "a" is positive upward facing parabola and a maximum point when "a" is negative downward facing parabola.

The points (0, 5) and (4, 13) lie on the graph of a linear function. What is the rate of change of the function?
Viefleur [7K]
The rate of change is the slope of this line
m = (y2 - y1)/(x2 - x1) = (13 - 5)/(4 - 0) = 8/4 = 2
