Explain the steps necessary to solve the following multi-step equation. Include the final solution as part of your submission and explain how
you verified that the solution is correct.
–5(1 – 5x) + 5(–8x - 2) = -4x – 8x

Answers

Answer: x = -5

-------------------------------------------------------------------------------------------------------------

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(1−5x)+5(−8x−2)=−4x−8x                                                                                                                          

-------------------------------------------------------------------------------------------------------------

Step 1: Simplify both sides of the equation.

−5(1−5x)+5(−8x−2)=−4x−8x

(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)

−5+25x+−40x+−10=−4x+−8x

(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)

−15x+−15=−12x

−15x−15=−12x

-------------------------------------------------------------------------------------------------------------

Step 2: Add 12x to both sides.

−15x−15+12x=−12x+12x

−3x−15=0

-------------------------------------------------------------------------------------------------------------

Step 3: Add 15 to both sides.

−3x−15+15=0+15

−3x=15

-------------------------------------------------------------------------------------------------------------

Step 4: Divide both sides by -3.

−3x /−3  = 15/ −3

x=−5

-------------------------------------------------------------------------------------------------------------

Answer:

x=−5

The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the ________property of multiplication.

Answers

Answer:

The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the Commutative property of multiplication.

Step-by-step explanation:

Commutative property is A × B = B × A

So the equation  4 ∙ 5 = 5 ∙ 4 is same as commutative property

Answer:

The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the commutative property of multiplication.

Step-by-step explanation:

The commutative property means that the positions of the numbers on each side of the equation can be swapped and both sides would be equal.

You can think of it as A x B = B x A

In 2010, the average cost of electricity was 11.54 cents per kilowatt hour. In 2014, the average cost of electricity
was 12.52 cents per kilowatt hour.
Which function models the average retail price of electricity, f(x), in cents per kilowatt hour, x years after 2010?
A. f(x) - 0.98x + 4.00

B. f(x) = 0.245x + 11.54

C. f(x) = 0.738x + 11.54

D. f(x) = 4.082x + 1962.89

Answers

Answer:

B

Step-by-step explanation:

First take 12.52 and subtract 11.54 to find the amount it had decreased. (.98)

After that, divide it by 4 (because it increased by .98 over 4 years) and you get .245 a year.

and sense your starting value was 11.54 the +11.54 also checks out

Gage Millar, algebra 2 tutor.

The function modeling the given situation of retail price of electricity in cents per kilowatt hour, x years after 2010 is: Option C. [tex]f(x) = 0.245x + 11.54[/tex] (in cents/kilowatt hour)

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Since the problem asks us to find the cost of electricity x years after 2010, thus, the increasing rate will add up itself x times and this addition will then be added to the price which is getting increased, which is 2010's price.

(since 2011's price = price of 2010 + constant increment,

2012's price = price of 2010 + twice of constant increment, and so on for further years)

Thus, f(x) = increment per year times x + price in 2010

Now assuming that increment in price per year is constant, we see:

Increment per year in electricity price= (price in 2014 - price in 2010)/4

Increment per year in electricity price = (0.98)/4 = 0.245 cents per year

Thus, we get:

[tex]f(x) = 0.245x + 11.54[/tex] as the price of the electricity in cents per kilowatt hour after x years from 2010.

Lin’s job pays$8.25 an hour plus$10 of transportation allowance each week. She has to work at least 5 hours a week to keep the job, and can earn up to $175 per week (including the allowance). 1.Represent this situation mathematically. If you use variables, specify what each one means. 2.How many hours per week can Lin work? Explain or show your reasoning.
