Answer:
x = 14
Step-by-step explanation:
(4y - 10) + 3x = 180
in other hand: 4y - 10 = 9x + 12
so : (9x + 12) + 3x = 180
9x + 3x = 180 - 12
12x = 168
x = 168/12
x = 14

Which choice is a linear function?
Explain
Please Help
Answer:
Option C
Step-by-step explanation:
Given the following question:
Using the process of elimination, we can find the answer:
It's not option A, because in order for a table to be a linear function the change of x, and the change of y have to be constant. In this case our change in y goes through -2, to -1. Which means option A is not a linear function.
It's not option A because again in order for a table to be a linear function the change of x and the change of y have to be constant. In this case our change of x is constant but our change in y isn't.
It's not option D because in order to have a linear function, you have to be able to rewrite the function into slope intercept (y = mx + b) in this case we only have one real number which is 12, while having our x, and y variable. Which means option D isn't a function.
Which leaves option C or "4x + 3y = 12" which is your answer, because it can be rewritten in slope intercept form.
Hope this helps.

I think it would be 2/8 but I know I probably wrong
Answer:
1/4
Step-by-step explanation:
probability is the number of possible solutions over the number of outcomes, so in this example, you would take the 2 possibilities of getting a red M&M, and pot it over all the possible M&Ms you could get, so it is 2/8, which simplifies to 1/4, so you are correct

You want to know the mean number of hours music students at your school practice each week. At each of three music classes you randomly survey 10 students. Your results are shown. Use all three samples to make one estimate for the mean number of hours music students practice each week. Round to the nearest hundredth if necessary. Hours Practiced Each Week A: 6, 5, 5, 6, 4, 6, 8, 5, 2, 6 B: 0, 6, 6, 5, 4, 5, 6, 3, 4, 9 C: 4, 5, 6, 4, 3, 2, 2, 3, 12, 1 The mean of all the sample data is hours.
The mean of a dataset is the average of the dataset
The mean of all the sample data is 4.67 hours
How to determine the meanThe datasets are given as:
Week A: 6, 5, 5, 6, 4, 6, 8, 5, 2, 6
Week B: 0, 6, 6, 5, 4, 5, 6, 3, 4, 9
Week C: 4, 5, 6, 4, 3, 2, 2, 3, 12, 1
The mean of a dataset is:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
Week A
[tex]\bar x_A = \frac{6+ 5+ 5+ 6+ 4+ 6+ 8+ 5+ 2+ 6 }{10}[/tex]
[tex]\bar x_A =5.3[/tex]
Week B
[tex]\bar x_B = \frac{0+ 6+ 6+ 5+ 4+ 5+ 6+ 3+ 4+ 9}{10}[/tex]
[tex]\bar x_B = 4.8[/tex]
Week C:
[tex]\bar x_C = \frac{4+ 5+ 6+ 4+ 3+ 2+ 2+ 3+ 12+ 1}{10}[/tex]
[tex]\bar x_C = 4.2[/tex]
Calculate the mean for the three weeks
[tex]\bar x = \frac{5.3 + 4.8 + 4.2}{3}[/tex]
[tex]\bar x = 4.76[/tex]
Hence, the mean of all the sample data is 4.67 hours

for p(x) = 5x^3-2x^2+3x-6.is x=-1 is a root of p(x)?is x=1 is a root of p(x)
Answer:
just x = 1 is a root.
Step-by-step explanation:
p(-1) = 5(-1)³ - 2(-1)² + 3(-1) - 6 = -5 - 2 - 3 - 6 = -26
so x= -1 isn't root for p(x)
p(1) = 5(1)³ - 2(1)² + 3(1) - 6= 5 - 2 + 3 - 6= 0
so x = 1 is a root for p(x)
a1 = -2 r=-2 Sn=22 Determine the number of terms of n in the series
A series can be an arithmetic series or geometric series
The series is undefined
How to determine the number of terms?The given parameters about the geometric series are:
a1 = -2 --- the first term
r=-2 --- the common ratio
Sn=22 --- the sum of n terms
The sum of n terms of a geometric series is represented as:
[tex]S_n = \frac{a(r^n - 1)}{(r-1)}[/tex]
Substitute known values
[tex]22 = \frac{-2((-2)^n -1)}{(-2-1)}[/tex]
This gives
[tex]22 = \frac{-2((-2)^n -1)}{(-3)}[/tex]
Divide both sides by -2
[tex]-11 = \frac{((-2)^n -1)}{(-3)}[/tex]
Multiply both sides by -3
[tex]33 = (-2)^n -1[/tex]
Add 1 to both sides
[tex](-2)^n = 34[/tex]
Take the natural logarithm of both sides
[tex]n\ln(-2) = \ln(34)[/tex]
Solve for n
[tex]n= \frac{\ln(34)}{\ln(-2) }[/tex]
The above number is a complex number.
Hence, the series is undefined

A sales associate earned a commission of $26.40 for sales totaling $220.00.
Which proportion could be used to find the commission amount for sales totaling $515.00?
26.4/220=x/515
x/26.4=220/515
220/x=26.4/515
26.4/220=515/x
Answer:
The first option
Step-by-step explanation:
Hello!
We want to find the correct proportion. 26.40/220 is the correct proportion for the amount earned because the associate earned $26.40 out of $220. The term "out of" is division.
Now, we have to match the format, where the commissions are the numerator, and the total is the denominator.
So we have x in the numerator (the same as 26.40) and 515 in the denominator (the same as 220).
This would be the first option : [tex]\frac{26.40}{220} = \frac{x}{515}[/tex]
Let's use ratios
Let that be x[tex]\\ \rm\rightarrowtail \dfrac{26.40}{220}=\dfrac{x}{515}[/tex]
[tex]\\ \rm\rightarrowtail 0.12=x/515[/tex]
[tex]\\ \rm\rightarrowtail x=515(0.12)[/tex]
[tex]\\ \rm\rightarrowtail x=61.8[/tex]

Using complementary angles, it is found that the solution to the trigonometric equation is of x = 20.
What are complementary angles?Complementary angles are two angles whose measures add to 90º.
If two angles a and b are complementary, we have that the sine of one is the cosine of other, that is:
[tex]\sin{a} = \cos{b}[/tex]
In this problem, the equation is:
[tex]\sin{(2x)} = \cos{(x + 30)}[/tex]
Hence, they are complementary, which means that:
[tex]2x + x + 30 = 90[/tex]
[tex]3x = 60[/tex]
[tex]x = \frac{60}{3}[/tex]
[tex]x = 20[/tex]
