Answer:

Part a) The variables are

x (the number of packages of Twinkies that were sold)

y (the number o boxes of juice that were sold)

Part b) The system of equations is

$x+y=79$ and $1.65x+1.36y=118.17$

Part c) $x=37,y=42$

Part d) The value of y represent the number of boxes of juice that were sold $y=42\ boxes\ of\ juice$

The value of x represent the number of packages of Twinkies that were sold $x=37\ packages\ of\ Twinkies$

Step-by-step explanation:

Part a) Define the variables in this situation

Let

x-----> the number of packages of Twinkies that were sold

y----> the number of boxes of juice that were sold

Part b) Write a system of equations that model the problem

we know that

$x+y=79$ ------> equation A

$1.65x+1.36y=118.17$ ---> equation B

Part c) Use the linear combination method to find the solution to the system you wrote in part b

Multiply equation A by -1.65

$-1.65(x+y)=-1.65*79$

$-1.65x-1.65y=-130.35$ ------> equation C

Adds equation C and equation B

$-1.65x-1.65y=-130.35\\1.65x+1.36y=118.17\\---------\\-1.65y+1.36y=-130.35+118.17\\-0.29y=-12.18\\y=42$

Find the value of x

$x+y=79$

$x+42=79$

$x=79-42=37$

Part d) Using a complete sentence, explain what the solution found in part c represents

The value of y represent the number of boxes of juice that were sold

$y=42\ boxes\ of\ juice$

The value of x represent the number of packages of Twinkies that were sold

$x=37\ packages\ of\ Twinkies$

My license plate is a 4-digit number. The products of the digits is 0; their sum is 9; the numbers appear in descending order; a

Lilit [14]

The product of the 4 numbers is 0. that means that one or more of the numbers is 0. because they appear in defending order we know that the digit in the ones place is 0. the only common factor of 10 and 15 is 5 so we know that our number is 5 _ _ 0. because they add up to 9 the second 2 digits have to add up to 4. the only two numbers that add up to four and are not the same(they have to be in descending order so it can't be the same digit twice) are 1 and 3 so your license plate is 5310

Write an equation that passes through the point (3,-9) and is parallel to the x-axis

Eddi Din [679]

Answer:

y = -9

Step-by-step explanation:

Any line that is parallel to the x-axis has a slope of 0.

since the y-value in the point is -9, that is the y-intercept.

So, our equation is y = -9.
