Answer:
The graph showing the temperature change over time is missing.
Step-by-step explanation: The slope of the line in the graph is the rate of temperature change per minute.
1. Calculate the slope between for each of the 3 ranges listed. Slope is rise/run: Take two points at the upper and lower boundaries of each range. You should have three sets of points:
e.g., (0,100) and (340, 175); (345, 176) and (360, 180); finally (360,185) and (380, 200). I made these up, since there is no graph. but the x values, the time in minutes, correspond to the ranges requested.
If the slopes are diferent, then explain that the rate of temperature rise is different for each segment.
3. Time is 360 + 60 = 420, temperature is 80: (420,80)

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

n, find the value of x and y.
35°
Answer:
x = 145, y = 35
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!

–5(1 – 5x) + 5(–8x - 2) = -4x – 8x
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
-------------------------------------------------------------------------------------------------------------

x=−5

Suppose you need to put a fence around a rectangular garden that has a perimeter of 64ft. The width is 12ft less than the length. Find the width and length of the garden.
Answer:
x=length
x-12=width
you techinally have to count 2 lengths and 2 widths.
2x + 2x - 24= 64
4x = 88
x = 22
so the length is 22 and the width is 10

Find the Slope of the line graphed?
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

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

n = -8 is the right answer.19. Helen has 2 more than twice as many stamps as Gail. If Gail
buys 10 more stamps, she and Helen will have the same
number of stamps. How many stamps does each person have
now?
Answer:
x(Gail)=8 and y(Helen)=18
Step-by-step explanation:
2x+2=y and x+10=y
Plug y in and solve for x
2x+2=(x+10)
2x-x=10-2
x=8
Plug x in and solve for y
(8)+10=y
y=18
