How do I answer this equation? -3x+y=12. I'm supposed to find the function for it bt I don't know how. Can you guys help me out please
Answers
You can do this by adding 3x to both sides which would result in y = 3x + 12.
Also, math teachers typically want functions expressed in terms of f(x) instead of y. So, you can replace your y with that to get the final answer of f(x) = 3x + 12.
Answer:
[tex]y=3x+12[/tex]
Step-by-step explanation:
We have been given an equation in standard form [tex]-3x+y=12[/tex]. We are asked to write our given equation as a function.
We know that the function represents a relationship between input and output, where each input gives exactly single output.
To write our given equation as a function we need to convert our given equation into slope-intercept form of equation because in slope-intercept form, there is exactly one y output for each input of x.
[tex]y=mx+b[/tex], where,
m = Slope,
b = The y-intercept.
To convert our given equation into slope-intercept form, we need to get y on left side of our equation.
[tex]-3x+3x+y=3x+12[/tex]
[tex]y=3x+12[/tex]
Now our equation is in form of a function, where each value of x gives exactly one y value.

Two squares are drawn. The larger Square has area of 400 in.². The area of the two squares have a ratio of 1 to 4. What is the side length S of the smaller square?
Answers
For this, we use the following relationship:
A1 / A2 = 4/1
Substituting:
400 / A2 = 4/1
From here, we clear A2:
A2 = (1/4) * (400)
A2 = 100 in ^ 2
We now look for the side of the small square, we use the following relationship:
A = S ^ 2
We cleared S:
S = root (A)
S = root (100)
S = 10 in
Answer:
the side length S of the smaller square is:
S = 10 in
Answer: S=10 in

A circle has a radius of 12.6 cm.
What is the exact length of an arc formed by a central angle measuring 120°?
Enter your answer in the box. Express your answer using π .
Answers
[the length of a circumference]=2*pi*r

What are the equations of the horizontal asymptotes of y = (4e^x+7)/(e^x-1) in the xy plane?
Answers
[tex] \lim_{x \to \infty} f(x) [/tex] = n
where n is a finite number.
in your case you have to caculate separately the two limits:
a) [tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 } [/tex] = [tex] \frac{\infty}{\infty} [/tex]
To solve this, you need to regroup eˣ both on the numerator and on the denominator:
[tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = [tex]\lim_{x \to +\infty} \frac{4 e^{x} (1 + \frac{7}{ e^{x} } ) }{ e^{x} ( 1 - \frac{1}{ e^{x} } ) }[/tex]
At this point the two eˣ cancel out and the parenthesis tend to 1, therefore
[tex]\lim_{x \to +\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = 4
Your first horizontal asymptote is y = 4.
b) Let's calcuate now:
[tex]\lim_{x \to -\infty} \frac{4 e^{x} + 7 }{ e^{x} - 1 }[/tex] = [tex] \lim_{x \to -\infty} \frac{0 + 7}{0 - 1} [/tex] = -7
Therefore your second horizontal asymptote is y = -7
Your answer is, hence, y = 4 and y = -7 are horizontal asymptotes of the given function.
Final answer:
The horizontal asymptotes of the function y = (4e^x+7)/(e^x-1) are y = 4 and y = -7, occurring as x approaches positive and negative infinity respectively.
Explanation:
The equations of the horizontal asymptotes of the given function y = (4e^x+7)/(e^x-1) can be found by analyzing the behavior of the function as x approaches positive or negative infinity. In this function, as x approaches infinity, e^x grows much faster than any constant, so the constants can be considered negligible. Thus, the behavior of the numerator and denominator is dominated by the terms involving e^x. As x tends towards infinity, the function approaches the ratio of the coefficients of e^x, which is 4/1, meaning the horizontal asymptote is y = 4. As x tends towards negative infinity, e^x approaches zero, and the function approaches 7/(-1), so there is also an asymptote at y = -7.
It is given that there is a vertical asymptote at x = -1, where the denominator becomes zero and hence "blows up".

y = 3x + 14
y = 2x3 + 4x2 – x + 5
y = –3x2 + 4x + 9
Answers
Roots are both: x=-4, x= -1/2 , x= 1
Proof:
Solve for x over the real numbers:
2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9
Subtract -3 x^2 + 4 x + 9 from both sides:
2 x^3 + 7 x^2 - 5 x - 4 = 0
The left hand side factors into a product with three terms:
(x - 1) (x + 4) (2 x + 1) = 0
Split into three equations:
x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0
Add 1 to both sides:
x = 1 or x + 4 = 0 or 2 x + 1 = 0
Subtract 4 from both sides:
x = 1 or x = -4 or 2 x + 1 = 0
Subtract 1 from both sides:
x = 1 or x = -4 or 2 x = -1
Divide both sides by 2:

Answer:

Step-by-step explanation:
I took the test and had the same question, plus the screenshot above
The Mean Absolute Deviation is 17.92.
What is Mean Absolute Deviation?The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data set. A measure of variance in a data set is the mean absolute deviation.
Take the absolute value of each digit in the data set, then deduct the mean. Next, add up the absolute values. The mean absolute deviation is then calculated by dividing the aforementioned sum by the total number of values in the data set.
Given:
Data set: {20, 24, 12, 44, 68}
Mean of the data = (20+ 24+ 12+ 44+ 68)/ 5 = 168/5
= 33.6
Mean Absolute Deviation
= {| 20- 33.6| + |24- 33.6| + |12-33.6| + | 44-33.6| + |68-33.36|} / 5
= (13.6+ 9.6 + 21.6+ 10.4 + 34.4 )/ 5
= 89.6/ 5
= 17.92
Hence, the Mean Absolute Deviation is 17.92.

Dr. Steve is working with a new radioactive substance in his lab. He currently has 64 grams of the substance and knows that it decays at a rate of 25% every hour.
Identify whether this situation represents exponential growth or decay. Then determine the rate of growth or decay, r, and identify the initial amount, A.
Answers
[tex]y=A(1-r)^{x}[/tex]
where
[tex]y[/tex] is the amount after a time [tex]x[/tex]
[tex]A [/tex] is the initial amount
[tex]r[/tex] is the the decay percent in decimal form
The first ting we are going to do is find [tex]r[/tex] by dividing our decay rate of 25% by 100%: [tex]r= \frac{25}{100} =0.25[/tex].
We also know from our problem that [tex]y=64[/tex]. Lets replace [tex]y[/tex] and [tex]r[/tex] in our formula:
[tex]64=A(1-0.25)^{x} [/tex]
[tex]64=A(0.75)^{x} [/tex]
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.
Now, to find the initial amount, we are going to solve our equation for [tex]A[/tex]:
[tex]64=A(0.75)^{x} [/tex]
[tex]A= \frac{64}{0.75 ^{x} } [/tex]
Notice that [tex]A[/tex] will depend on the number of ours [tex]x[/tex].
Answer:
This situation models exponential decay because the substance decays with time.
The radioactive substance decays at the rate of : 25%
r=25/100 =0.25
The initial amount of substance is 64 grams. So, . A=64

The radius of a circle is 1 foot. What is the length of a 45 degree arc
Answers
The length of a 45 degree arc on a circle with a radius of 1 foot is π/4 feet.
Explanation:The length of a 45 degree arc can be calculated using the formula for the circumference of a circle. The formula for the circumference is given by C = 2πr, where r is the radius of the circle. In this case, the radius is given as 1 foot. So, we can plug in the values to calculate the circumference as C = 2π(1) = 2π feet.
To find the length of a 45 degree arc, we need to find the fraction of the circumference that corresponds to a 45 degree angle. Since a full circle is 360 degrees, a 45 degree angle is 45/360 = 1/8 of the circumference. Therefore, the length of a 45 degree arc is 1/8 of the circumference, which is (1/8)(2π) feet.
Simplifying this expression, we get the length of a 45 degree arc as (1/8)(2π) = π/4 feet.

What is the slant height of a square pyramid that has a surface area of 279 square meters and a side length of 9 meters?
Answers
Answer:
l = 11 meters
Step-by-step explanation:
Surface area = s² + 2s*l
Where "l" is the slant height
Given: Surface area = 279 ; side length s = 9
Now plug in these values in the above formula, we get
279 = 9^2 + 2*9*l
279 = 81 + 18*l
18l = 279 - 81
18l = 198
Dividing both sides by 18, we get
l = 198/18
l = 11 meters
Therefore, slant height of the square pyramid = 11 meters

Answer is B.
Answer:
B. The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
Step-by-step explanation:
We have,
The function representing the price charged by the customers is [tex]c(x)=50+5x[/tex].
The function representing the number of customers is [tex]p(x)=100-2x[/tex].
Then, the product of the functions is given by,
[tex](p\times c)(x)=p(x)\times c(x)\\\\(p\times c)(x)=(100-2x)(50+5x)\\\\(p\times c)(x)=-10x^2+400x+5000[/tex]
Substituting x = 2 in the above product gives,
[tex](p\times c)(2)=-10\times 2^2+400\times 2+5000\\\\(p\times c)(2)=-40+800+5000\\\\(p\times c)(2)=\$ 5760[/tex]
Also, the charge per customer when x = 2 is,
[tex]c(x)=50+5x\\\\c(x)=50+5\times 2\\\\c(x)=50+10\\\\c(x)=\$ 60[/tex]
Hence, the product (p-c)(2) represents,
B. The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
