Answer:
The answers are "(f+g)(x)> 3 for all values of x" and "(f+g)(x)<6 for all values of x".
Step-by-step explanation:
If f(x) = 1x1 + 9 =10, then f(x) is a constant for every value of x, which means that y=f(x) will take the value of 10 no matter which value takes x.If g(x)= -6, then g(x) is a constant for every value of x, which means that it will take the value of -6 no matter the value of x.(f+g)(x)=10 + (-6) = 10 - 6= 4. Then, no matter the value of x, the function (f+g)(x) will equal 4 (a constant). According to the available options, both "(f+g)(x)>3" and "(f+g)(x)<6" are true, because (f+g)(x)=4>3 and (f+g)(x)=4 <6.(3x+2x^4)+(3x-5x^4)
Answer:
6x -3x^4
Step-by-step explanation:
Eliminate parentheses. Since the multiplying coefficient is +1, the parentheses can simply be dropped:
= 3x +2x^4 +3x -5x^4
Add like terms (ones with the same exponent on the variable).
= 3x +3x +2x^4 -5x^4 . . . . . . . group like terms together
= (3+3)x +(2-5)x^4
= 6x -3x^4

Elena agrees to finish a knitting project for a friend. The graph shows the number of rows Elena completes compared to the amount of time spent knitting.
Assuming she worked at a constant rate, how many rows had been completed before Elena started working?
12
14
15
19
The graph that accompanies this question is in the figure attached.
Answer:
12
Explanation:
The assumption that Elena worked at a constant rate permits you to build a linear model for the the number of rows Elena completes (dependent variable) in function of the time spent knitting (independent variable).
The coordinates of the points shown on the graph are (14,19), (20,22), and (30,27), and you need to find how many rows had been completed before Elena started working.
The number of rows that had been completed before she started working is the number of rows for time equal 0, which is the y-intercept of the function that models the situation.
Then, what you need to do is to find the equation of the line, using two of the three given points, and then tell the y-intercept.
a) Find the slope, m:
m = rise / run = Δy / Δx = (22 - 19) / (20 - 14) = 3 / 6 = 1/2 = 0.5b) Use one point (20, 22) to find the equation of the line:
y - y₁ = m (x - x₁) ← point-slope formy - 22 = 0.5 (x - 20)y = 0.5x - 10 + 22y = 0.5x + 12 ← slope intercept formThe constant term of the slope-intercept equation, ie. 12, represents the y-intercept. Thus, your answer is 12.

What number has 3 hundreds, 4 more tens than hundreds, and 1 more one than hundreds?
The number that has 3 hundreds, 4 more tens than hundreds, and 1 more one than hundreds is 374.
Explanation:The student is asking us to construct a number based on place value criteria. To assemble this number, we will assign the digits to their appropriate places based on the given conditions. Three hundreds means the hundreds place must be 3, so we have '3' in the hundreds place. Since there are 4 more tens than hundreds, we add 4 to 3, giving us 7, which becomes the digit in the tens place. Lastly, there is 1 more one than hundreds, meaning we need to add 1 to 3 to get 4 for the ones place. Therefore, our number is 374, as it meets all the conditions: 3 hundreds, 7 tens (which is 4 more than the hundreds), and 4 ones (which is 1 more than the hundreds).
hamburgers cost $2 per lbs and chicken costs $3 lbs and you only have $30 to spend and expect At least 3lbs of hamburger
If you want at least 3 pounds of hamburgers, then $6 is enough to buy those 3 pounds of hamburgers. If you ONLY buy 3 Pounds, then you also have enough for 4 pounds of chicken. $3 a pound x 4 = $12. You have 2 dollars left to spare, which means you can buy another pound of hamburgers. So 4 pounds each are able to be purchased.

Mrs. Miller sells a house for $179,000. If she earns a commission of 6%, how much money does she earn? Write a proportion and show your work.
Please check my work.
I think that my answer would still be the same because $179,000
- 6%
-----------------------
$179,000
Answer:
The amount of money which she earn as commission after selling the house is $ 10,740 .
Step-by-step explanation:
Given as :
The selling price of the Mrs. Miller house = $ 179, 000
The percentage of commission which she earn = 6 % of the selling price
Let the amount of money she earn = $ x
Now, According to question
The amount of money she earn = 6 % of the selling price of house
I.e the amount of money she earn = [tex]\frac{6}{100}[/tex]×$ 179,000
Or, the amount of money she earn = 6 × 1790
∴ The amount of money which she earn as commission = $ 10,740
Hence The amount of money which she earn as commission after selling the house is $ 10,740 . Answer
Mrs. Miller earns a commission of $10,740 on selling a house for $179,000.
Explanation:To solve this problem, we need to calculate 6% of $179,000. The commission amount can be found by multiplying $179,000 by 6% (or 0.06). So, the commission earned by Mrs. Miller would be $179,000 * 0.06 = $10,740. Therefore, Mrs. Miller earns $10,740 as her commission.

210 will be left in 330 days. Round your answer 4 decimal places and remember to
use labels.
Answer:
59.0891 g (rounded to 4 decimal places)Explanation:
Half-life time of a radioactive substance is the time for half of the substance to decay.
Thus, the amount of the radioactive substance that remains after a number n of half-lives is given by:
[tex]A=A_0\cdot (1/2)^n[/tex]Where:
A is the amount that remains of the substance after n half-lives have elapses, andA₀ is the starting amount of the substance.In this problem, you have that the half-live for your sample (polonium-210) is 138 days and the number of days elapsed is 330 days. Thus, the number of half-lives elapsed is:
330 days / 138 days = 2.3913Therefore, the amount of polonium-210 that will be left in 330 days is:

If the vine continues to grow at this rate, it will be. Inches long at the end of 5 weeks
Help ASAPP!!!!
Answer:
The growth at week 5 is 20 inches
Step-by-step explanation:
Topic: Arithmetic Progression
Given
From the table,
At Week 1: Total length = 4
At Week 2: Total length = 8
At Week 3: Total length = 12
There are two ways of solving this;
Method 1
Between each interval, the vine grows by 4 inches. This is supported by the calculation below
From week 1 to week 2; 8 - 4 = 4 inches
From week 2 to week 3; 12 - 8 = 4 inches
This means that; the vine will grow by 4 inches to week 4;
Hence, at week 4;
Total length = Week 3 + 4
Total length = 12 + 4 = 16
Similarly, the vine will grow by 4 inches to week 5;
Hence, at week 5
Total length = Week 4 + 4
Total length = 20 + 4 = 24
But this method is not always advisable because it'll be tedious to use for large data; hence the need for method 2
Method 1
Between each interval, the vine grows by 4 inches. This is supported by the calculation below
Here, we make use of arithmetic progression formula
[tex]T_{n} = a + (n - 1)d[/tex]
Take note of the following
a = First term = The growth at first week
a = 4
d = common difference = rate of growth
From week 1 to week 2; the rate of growth is 8 - 4 = 4 inches
From week 2 to week 3; the rate of growth is 12 - 8 = 4 inches
So, d = 4
n = nth term = 5; i.e the 5th week
Tn = the rate of growth at nth week;
In this case, Tn = 5
By substitution
[tex]T_{n} = a + (n - 1)d[/tex] becomes
[tex]T_{5} = 4 + (5 - 1)4[/tex]
[tex]T_{5} = 4 + 4 * 4[/tex]
[tex]T_{5} = 4 + 4 * 4[/tex]
[tex]T_{5} = 20[/tex]
Hence, the growth at week 5 is 20 inches
On the first day of June, there were about 17.86 h of daylight in a city. Five months later, there were about 8.40 h of daylight. What was the percent decrease?(Round to the nearest whole number as needed.)
The percent decrease is 53%
Step-by-step explanation:
The percent decrease is given by:
[tex]Percent-Decrease = \frac{Old\ value-New\ value}{Old\ value} * 100[/tex]
Here
Old Value = 17.86 hours
New Value = 8.40 hours
So,
[tex]Percent-Decrease = \frac{17.86-8.40}{17.86}*100\\=\frac{9.46}{17.86}*100\\=0.5296*100\\=52.96\%[/tex]

Given: △AKM, KD ⊥ AM , AK = 6, KM = 10, m∠AKM = 93º Find: KD
Final answer:
To find the length of KD in ΔAKM, where KD is perpendicular to AM, and given AK = 6, KM = 10, and m∠AKM = 93º, we use trigonometry. Using the sine function, we determine that KD ≈ 9.99.
Explanation:
The question is about finding the length of KD, where KD is perpendicular from K to AM in triangle AKM, given AK = 6, KM = 10, and the measure of angle AKM is 93º. To solve this, we can use trigonometry, specifically the functions related to a right-angled triangle.
Since KD is perpendicular to AM, ΔAKD is a right-angled triangle at D. We can use the sine function, which is defined as the ratio of the length of the opposite side to the hypotenuse. In this case, α = m∠AKM, opposite = KD, and hypotenuse = KM.
Therefore, sine(α) = opposite/hypotenuse = KD/KM. Since we know that sine(93º) ≈ 0.999, KM = 10, we can find KD by rearranging the equation: KD = KM × sine(93º). Substituting the values gives KD = 10 × 0.999 ≈ 9.99.
In a given rectangle, the shorter side is 3 units less than the longer side. If we let the longer side be represented by the variable x, create an expression that represents the perimeter of the rectangle. (P=2L+2W)
The expression representing the perimeter of the rectangle with the longer side x and the shorter side 3 units less than the longer side is P = 4x - 6.
If the longer side of a rectangle is represented by the variable x, and the shorter side is 3 units less than the longer side, then the shorter side can be expressed as x - 3. The perimeter (P) of a rectangle is given by the formula P = 2L + 2W, where L is the length (the longer side) and W is the width (the shorter side). Plugging in the expressions for L and W in terms of x, the perimeter of the rectangle can be represented as P = 2x + 2(x - 3).
Simplifying this expression, we get P = 2x + 2x - 6, which simplifies further to P = 4x - 6.
Therefore, the expression that represents the perimeter of this specific rectangle is P = 4x - 6.

The first three terms of a geometric sequence are as follows. -5, 20, -80 find the next two terms of a sequence give exact values
Answer:
320, -1280
Step-by-step explanation:
r = -4
-5 , 20 , -80 , 320 , -1280
Final answer:
The next two terms of the geometric sequence (-5, 20, -80) are 320 and -1280, determined by multiplying each term by the common ratio of -4.
Explanation:
To find the next two terms of the given geometric sequence (-5, 20, -80), we need to determine the common ratio. We can calculate the common ratio by dividing the second term by the first term or the third term by the second term.
The common ratio (r) is:
r = 20 / (-5) = -4
r = (-80) / 20 = -4
Now that we know the common ratio is -4, we use it to find the next two terms by multiplying the most recent term of the sequence by the common ratio.
Fourth term: -80 × -4 = 320
Fifth term: 320 × -4 = -1280
The next two terms of the sequence are 320 and -1280.
y+4/12 – y–1/12 = y/2
The value of "y" is 3
Solution:Given that,
[tex]y+\frac{4}{12}-y-\frac{1}{12}=\frac{y}{2}[/tex]
We have to solve for "y"
Let us simplify the given expression and solve for"y"
[tex]y+\frac{4}{12}-y-\frac{1}{12}=\frac{y}{2}[/tex]
On cross multiplication in L.H.S we get,
[tex]\frac{12 y+4-12 y-1}{12}=\frac{y}{2}[/tex]
Cancelling denominator 12 from both sides, we get
12y + 4 -12y - 1 = y
Again cancelling +12y and -12y we get
4 - 1 = y
y = 3
Thus the value of "y" is 3

Unfortunately, the plane was delayed for 1 5/6 hours. How long did the trip finally take?
Answer:
Finally, the trip of Thomas will take an hour and fifty minutes more than the normal time it usually takes.
Step-by-step explanation:
1. Let's check all the information provided to answer the question:
Time of Thomas flight delay = 1 5/6 hours
Time of normal flight = x hours
2. How long did the trip finally take?
For calculating how long the trip finally took, we need to do the following sum:
Time of normal flight + Time of delay
Like we don't know the time of the normal flight, we will define it as x, then:
x + 1 5/6 hours
x + 1 hour and 50 minutes ⇒ 5/6 of an hour = 5/6 * 60 minutes = 50 minutes
Finally, the trip of Thomas will take an hour and fifty minutes more than the normal time it usually takes.
