Answer:
x=-20
Step-by-step explanation:
x+8−8=−12−8
x=−20
Answer:
The answer is -20
Step-by-step explanation:
X+8=-12
You subtract 8 from the left the the right side of the equal sign.
This leaves: X=-20
The reason is, when you subtract a negitive from a negitive you add them together given that they have the same + or - sign. In this case, they are both negitive.
12+8 equals 20
But because it's negive you have to add them together.

Options-

Answers
Answer:
H(23)=55 - 55% of U.S households had internet use in 2003.
H(4)=k - k% of U.S households had internet use in 1984.
H(27)≥61 - At least 61 percent of U.S households had internet use in 2007.
H(17)+H(21)≈H(29) - The sum of the percents of U.S. households with internet use in 1997 and 2001 is about the same as the percent of U.S. households with internet use in 2009.
Step-by-step explanation:
I have no idea how to explain, oh well.
From the function, the correct interpretations are:
1. 55% of U.S. households had internet use in 2003.
2. k% of U.S. households had internet use in 1984.
3. At least 61% of U.S. households had Internet use in 2007.
4. The sum of the percents of U.S households with Internet use in 1997 and 2001 is the same as the percent of U.S households with Internet use in 2009.
---------------------------
The function H(x) represents the percentage of households with Internet in x years after 1980, thus x is the number of years after 1980 and H(x) is the percentage of households with internet in year 1980 + x.
1. H(23)=55
1980 + 23 = 2003, thus 55% of U.S. households had internet use in 2003.2. H(4)=k
1980 + 4 = 1984, thus k% of U.S. households had internet use in 1984.3. H(27)≥61
1980 + 27 = 2007, thus: At least 61% of U.S. households had Internet use in 2007.4. H(17)+H(21)≈H(29)
Following the same logic as previous items, as considering that the output is a percentage: The sum of the percents of U.S households with Internet use in 1997 and 2001 is the same as the percent of U.S households with Internet use in 2009.A similar problem is given at https://brainly.com/question/24242199

Mohammed built a building that can carry up to 5 tons. If each person weighs about 150 pounds, how many people can fit onto the building that Mohammed built?
Answers
Answer:
Step-by-step explanation:
To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).
2,000 lbs. = 1 T.
X 5 X 5
10,000 lbs. = 5 T.
Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.
10,000/150=66.6666666667

Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is

15? = 360 ( divide both sides by 15 )

Area formula for rectangle:
A = whWe see the width of the white part of the banner is 3x - 2 and height is 2x
Function to define the area
f(x) = (3x - 2)*2x = 6x^2 - 4xb.
If maximum width of white area is 10 ft, then the dimensions are:

Answer:
The answer is 25.
Step-by-step explanation:
This is actually very simple but other percentages would be harder. 50% s the same as 1/2 or 0.5. all you have to do is divide 50/2 which is 25. 25 is 50% of 50.

Measuring the Wind Speed of a HurricaneWhen measuring the wind speed of a hurricane or similar storm, meteorologists don’t want to get hit by flying debris. They use a measure available to them in the comfort of their TV studio. Luckily for the meteorologists, the barometric pressure is linearly related to the wind speed.Suppose scientists compared the wind speeds and barometric pressure readings of two severe storms over the Atlantic Ocean. For one of the storms, the barometric pressure was 1,000 mb (millibars), and the maximum wind speed was 100 kmh (kilometers per hour). The second had a barometric pressure of 960 mb and maximum wind speeds of 180 kmh. (a)Develop a rule that you could use to predict the wind speed given any barometric pressure.(b)Use your rule to predict the wind speed of a hurricane with a barometric pressure of 980 mb. Using what you know about linearity, explain why your prediction is reasonable. (c)Interpret the intercept for wind speed in this context (i.e., as it pertains to the weather).(d)Explain the meaning of slope in this context.
Answers
Answer:
So i found the teacher notes after hours of looking here are the exact answers so i would recommend changing the wording.
Part A: Ordered pairs in the form (mb, kmh): (1,000, 100) and (960,180) Let X be the barometric pressure and Y be the wind speed.
Slope= (180-100)
---------------- = -2
(960-1000)
Formula: y=-2(x-1000)+100
Part B: y=-2(980-1000)+100=140
140 kmh is reasonable. Because 980 mb is halfway between 960 mb and 1000 mb, we should expect a wind speed halfway between 180 kmh and 100 kmh.
Part C: The wind speed intercept is (0,2100) [or (2100,0) if written that way.] This means that when brometric pressure is 0 mb, then the wind speed would be 2100 kmh. However in the context of real weather, this is an impossible situation.
Part D: The slope means that every decrease of 2 kmh in wind speed corresponds to a 1 mb increase in barometric pressure.
