Answer 1

Answer:

(x, y) = (no solutions, 0)

Step-by-step explanation:

2x - 4y = -10

2x + y = 10

(2x - 4y) - (2x + y) = -10 + 10

-3y = 0

y = 0

x has no solutions.

Module 06: Project Option 1
Instructions:

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.


Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.


Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.


2. Translate the new algebraic expression you created in Question 1 to a verbal expression.


Part 2: Writing Equivalent Expressions
3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.


a. Use either the commutative property or combine like terms to create an equivalent expression.


b. Use the distributive property to create an equivalent expression.


4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.



Part 3: Finish the Story
5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?



6. Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

Question 10 (2 points)
An economist creates a scatter plot comparing years of experience to yearly salary (in dollars) at a particular company. The trend line through the data can be described by the equation y = 9,000x + 25,000.

What is the slope and what does it mean?

Question 10 options:

9,000; For their every year of experience an employee has, their salary goes up by this amount.


25,000; For their every year of experience an employee has, their salary goes up by this amount.


25,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.


9,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.

Answers

Answer:

Question 6: The slope is 5/3 because the y-intercpet is your rise and it rose up 5 units and x-intercept is your run so it shifted 3 units to the right which means the whole thing is also positive.

Question 9: $135

Question 10: Its either the first or last option

Step-by-step explanation:

Answer:

The answer for question 6 would be 5/3

and for question 9 the answer would be 135

and I believe question 10 is 9,000; For their every year of experience an employee has, their salary goes up by this amount.

Step-by-step explanation:

Slope (also can be called rate of change) is solved by change in the y variable/change in the x variable or also known as rise/run

Painting:
Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need


(Also can you explain how you solved it? Just in case I've been doing all the other ones wrong)

Answers

Answer:

Step-by-step explanation:

First we need to find the area of the fence, since paint covers square feet and squared units refers to area.  The area of the fence is 26 x 7, which is 182 sq ft.  If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 1/350 = x/182  Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.

A gallon of paint with cover 365

What inverse operation would you perform on both sides to solve this equation?
4-c=26 and solve it pls

Answers

Answer:

c=-24

Step-by-step explanation:

You should perform the inverse of addition and multiplication

The inverse of addition is subtraction so we subtract 4 on both sides:

4-4-c=26-4

Which will be

-c=24

Divide by -1 since the inverse of multiplication is division

-c/-1=24/-1

So the answer will be:

c=-24

The answer to this equation should be c=-24 I Hope this helps

The answer is subtract two from both sides. Explanation: because it males the equation even and easier to solve.

Answer:

[tex] \underline{ \underline{ \boxed{ \text{Subtract \: 2 \: from \: both \: sides}}}}[/tex]

Step-by-step explanation:

Since we want constants only on the right hand side , we have to remove 2 which is on the left hand side. The opposite of +2 is -2 and whatever we do to one side , we must do to the other side. So, The first step that would be used to solve the equation should be Subtract 2 from both sides.
