Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
To change the or any equation to slope-intercept form or to identify the Y intercept you must follow some steps to make sure you get the right answer. For this I am going to just break down the equation and show how I get my answer.
First, we are going to just write out the equation, simple enough.*…show more content…*

(-2) – 2 To find the value of 3y all we must do is add 1,470 and the negative factor of 2x (–2x) + 1,470 = {3y} Let “/” represent a fraction. Now we are going to find the value of 3y/3 (–2x/3) + (1,470/3) = {3y/3} Then we are going to find the value of Y (–2x/3) + 490 = {y} For this word problem, after following the steps to find it, the Y-intercept is {490} and the slope is {-2/3x} Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences. Well in this case I guess I would find and graph the Y-intercept. And then I would take the pointer and move three times to the right of the graph and then two points to the bottom Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences. For this I am going to write the equation as so down below: F(x) = -2x/3 +

The converted equation is (t-1)^2 lne = e^3; at first, Kirby thought that it was easy and try to help me, but in result, when Mr.Marshall came by, he told that "lne" can be cancel out because "lne" is equal to 1, so wouldn't make any changes in the equation at all. Next, I square root both side after he told me to cancel out the "lne" and got t-1= e^3. I added 1 to both side and I got t=

Google Docs has built-in mathematical typesetting that is easy to use, allowing for both typed shortcuts and simply clicking the option on the menu (if the shortcut is forgotten). For more intensive purposes, the options available in Google Docs may not be sufficient, but for the purpose of this project it was adequate. While there is an add-on for Google Docs that allows for both the construction of equations and graphs, the graph is not created in real-time as the function is being entered.

886 Words | 4 PagesTo graph population or disease, we needed to use exponents; in equation-form, the exponent was an X, but it could be substituted for any number, which would represent the year. You would also find the current population or number of cases and divide them by the amount the previous year (the starting number) and add that to one to find the rate, which would show you if it was growth or decay. Finally, you use the starting number as your constant or y-intercept. If you were trying to graph the decay of a population, the equation could be: y=150,000(1.5)x; if you were trying to graph decay, the equation could be: y=150,000(0.5)x. You can replace X with any number (number of years) to find the population in the future (positive number) or in the past (negative numbers).
