Answer: Part A: 80 cents; Part B: 10 pounds of potatoes for 8 dollars.

Step-by-step explanation:

For part A I assume that 5 represents the pounds of potatoes and 4 is the number of dollars. So my ratio is now 5:4 if I am not wrong.

therfore the equation would be 5:4=1:x

Cross mulitiply and you get x=4/5 or 80 cents/pound

Part B:

This is pretty simple, 10,8 is just double the original simplified ratio of 5:4. Therfore 10,8 represents 10 pounds of potatoes for 8 dollars.

loris [4]

Answer:

yes

Step-by-step explanation:

These are like terms because they have the same variables and powers. The coefficients do not need to match for it to be considered a like term.

Sheila Total:: 6x
<span>Sherri Total:: 5(x+10) = 5x+50

</span><span>(a) Write an equation. Let x represent the amount of one of Sheila’s deposits.
6x = 5x+50

</span><span>(b) Solve the equation. Show your work.
x = 50

</span><span>(c) Check your solution. Show your work.
6*50 = 5(50+10)

Calculate had a net income of 8 million dollars in 2010, while a small competing company, Computate, had a net income of 3 milli

Lilit [14]

The question is an illustration of a linear function and an exponential function.

The given parameters are:

<u>Calculate Company</u>

Initial net income: $8 million

Rate: $0.5 million per year

<u>Computate Company</u>

Initial net income: $3 million

Rate: 20% each year

<h3>(a) Standard mathematical model</h3>

The model of calculate company is best represented using a linear function, while the computate is best modeled by an exponential function.

A linear function is represented as:

$y = mx + b$

Where:

m represents rate
b represents the initial value

An exponential function is represented as:

$y = a(1 + r)^x$

Where:

r represents rate
a represents the initial value

So, the functions are:

$y=8 + 0.5x$ --- calculate company

$y =3(1.2)^x$ --- computate company

See attachment for the graph of both functions

<h3>(b) Compare both functions</h3>

From the graph of both functions, we have the following comparison:

The calculate company has a higher y-intercept
The computate company follows a more realistic model

<h3>(c) The company to choose</h3>

In (b), we concluded that:

The computate company follows a more realistic model

Hence, it is better to invest in the computate company

<h3>(d) When both companies have the same net income</h3>

From the attached graph, both functions meet at approximately (8, 12)

This means that they have the same net income in 2018

The graphs do not meet again.

This means that, they would never have the same net income again
