Step-by-step explanation:

so y is equal to 35 because alternate interior angles are equal to each other (you can search this up if you're confused) and x = 145 because of supplementary angles so I did 180 - 35 = 145. hope this helps!

Answer:

slope of line 1

m = (-8 - 2) / (2 + 2)

m = -10/4 = -5/2

slope of line 2

m = (6 + 1) /(5 - 0)

m = 7/5

slope of line 3

m = (-2 + 7) /(2 - 4)

m = 5/ -2

m = -5/2

Line 1 and Line 2 are neither.

Line 1 and Line 3 are parallel since they have same slope.

Answers

Answer:

-1/2

Step-by-step explanation:

It is negative since the slope is declining, meaning that it is a negative slope!

It is 1/2 because we go down one and move 2 to the right, meaning that we get 1/2 and then for the negative slope get -1/2

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.

3.) The quotient property is applied: if two same bases divide with exponent values, then the exponents subtract, and the bases remain. Therefore, n^5 / n^3 = n^5-3 = n^2.

4.)The same rule is applied to this one because the bases (q) are the same variable, and the operation is division. q^2 / q^4 = q^2-4 = q^-2.
Now, we have a negative exponent, here’s what to do:
With a negative exponent, we picture a 1 under the q^-2, like this: q^-2 / 1. We can’t have a negative exponent. So, to get it of positive value, we move it down to where the 1 is. We then get: 1/q^2. We simply shifted it from the numerator to the denominator which cancels out the negative. Your answer is 1/q^2.

5.) 4^5 / 4^4 = 4^5-4 = 4^1 or just 4. This is because of the quotient property.

6.) (-3)^1 / (-3) ^1 = -3^1-1 = -3^0. Now we have an exponent of zero. Whenever you see an exponent to the value of zero, the whole entire base and exponent just becomes the whole number of 1. Therefore, -3^0 = 1 as your answer.

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.

Answers

Answer:

20

Step-by-step explanation:

($8.25 x 5 hours) + 10x <= 175

41.25 + 10x <= 175

x =4  that is 4 weeks

so multiple 5 hours by 4 to get 20 hours

that way she is earning 175 per week

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.
