Can Someone Please Tell Me How To Solve This And This Type Of Questions?

Answers

Answer 1
Hey! So you are going to find the coordinates of P and R
P is (4,0) R is (-6,-4)
Then you can plug it into this formula: (x1-x2)^2 + (y1-y2)^2
Using P and R coordinates that’s:
(4- -6)^2 + (0- -4)^2
10^2 + 4^2
100 + 16=
116
Then you are going to find the square root
So 116 square root is 10.8 rounding to the nearest tenth
Hope this helps!

I think the way they are telling is that the triangle will move to the third quadrant,

If so, then the coordinates of P'Q'R' will just be the negative of PQR.

Determine the equation of this line, pitting your answer in the form Ax + By + C = 0, where A B C are intergers.

Answers

Answer:

5x + 4y - 20 = 0

Step-by-step explanation:

1. Find the two points given: (0,5) and (4,0)

2. Find the slope of the line:

      m = [tex]\frac{5-0}{0-4} = \frac{-5}{4}[/tex]

3. Find y intercept by plugging in one point into the y-intercept form

      y = (-5/4) x + b

      0 = (-5/4) (4) + b

      b = 5

4. Write out the equation in y-intercept form

      y = (-5/4) x + 5

5. Rewrite it in Ax + By + C = 0 form

        (5/4) x + y - 5 = 0

6. Since A B C all need to be integers, multiply the whole equation by 4

       5x + 4y - 20 = 0

what is 6xy . 12 over x 100 over 6

Answers

Simplifying
X2 + -6xy + -12 = 0

Reorder the terms:
-12 + X2 + -6xy = 0

Solving
-12 + X2 + -6xy = 0

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '12' to each side of the equation.
-12 + X2 + 12 + -6xy = 0 + 12

Reorder the terms:
-12 + 12 + X2 + -6xy = 0 + 12

Combine like terms: -12 + 12 = 0
0 + X2 + -6xy = 0 + 12
X2 + -6xy = 0 + 12

Combine like terms: 0 + 12 = 12
X2 + -6xy = 12

Add '6xy' to each side of the equation.
X2 + -6xy + 6xy = 12 + 6xy

Combine like terms: -6xy + 6xy = 0
X2 + 0 = 12 + 6xy
X2 = 12 + 6xy

Simplifying
X2 = 12 + 6xy

Reorder the terms:
-12 + X2 + -6xy = 12 + 6xy + -12 + -6xy

Reorder the terms:
-12 + X2 + -6xy = 12 + -12 + 6xy + -6xy

Combine like terms: 12 + -12 = 0
-12 + X2 + -6xy = 0 + 6xy + -6xy
-12 + X2 + -6xy = 6xy + -6xy

Combine like terms: 6xy + -6xy = 0
-12 + X2 + -6xy = 0

–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

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.
