The standard form of the given equation is x - 3y = 6.
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given is an equation, y = 1/3 x - 2
The given equation is in slope intercept form, i.e. y = mx+ c, where m is slope and c is constant,
Here, slope (m) = 1/3 and constant (c) = -2
Converting the equation in standard form,
y = 1/3 x - 2
3y = x - 6
x - 3y = 6
Hence, the standard form of the equation is x - 3y = 6

Which equation represents a direct variation?
y = 2x
y = x + 4
y =1/2x
y = 3/x
Answer:
A. [tex]y=2x[/tex]
Step-by-step explanation:
We are asked to find the equation that represents a direct variation.
We know that a direct variation is in form [tex]y=kx[/tex], where y is directly proportional to x and k is constant of variation.
Upon looking at our given choices, we can see that equation [tex]y=2x[/tex] represents direct variation, where [tex]k=2[/tex].
Therefore, option A is the correct choice.
Solve the system by substitution.

Determine how many, what type, and find the roots for f(x) = x4 + 21x2 − 100.
Answer:
Step-by-step explanation:
We will make a substitution to make our work easier (when we get there). We also need to know that
[tex]i^2=-1[/tex]
We will use that as another substitution. First, let's make the job of factoring a bit easier. Here's the first substitution. We will let
[tex]x^4=u^2[/tex]
Therefore,
[tex]x^2=u[/tex]
Now we will write the polynomial in terms of u instead of x:
[tex]f(x)=u^2+21u-100[/tex]
Solve for the values of u by setting the polynomial equal to 0 and factoring. When you factor, you will get:
[tex](u+25)(u-4)[/tex]
But don't forget that
[tex]x^2=u[/tex]
so we have to put those back in now:
[tex](x^2+25)(x^2-4)=0[/tex]
By the Zero Product Property, either
[tex]x^2+25=0[/tex] or
[tex]x^2-4=0[/tex]
We will factor the first term. Solving for x-squared gives us:
[tex]x^2=-25[/tex] and
x = ±√-25
which simplifies down to
x = ±√-1 × 25
we can sub in an i-squared for the -1:
x = ±√[tex]i^2*25[/tex]
The square root of i-squared is "i" and the square root of 25 is 5, so
x = ±5i
The next one is a bit easier. If
[tex]x^2=4[/tex], then
x = ±2

A circle of radius 1 centered at (4, 0) is rotated about the y-axus. Draw a picture of the three-dimensional shape that is produced when the circle is rotated about the y-axis. In two or more complete sentences, describe the three-dimensional shape. Upload both parts A and B as your final answer.
When a circle rotates around the y-axis, it forms a three-dimensional object known as a cylinder. The cylinder will have a radius of 1 and height equal to the diameter of the circle, which is 2.
Explanation:When a circle of radius 1 centered at (4,0) is rotated about the y-axis, the three-dimensional shape that is produced is known as a cylinder.
This cylinder would have a radius of 1, and its height would be equal to the length of the diameter of the original circle, which is 2 units (from -1 to 1 along the x-axis).In terms of the visual representation, imagine a circle on a piece of paper, now pick up the paper and rotate it about the line that is the y-axis. The paper, on which the circle is drawn, forms a cylindrical shape when rotated. The edges of the paper represent the bases of the cylinder and the surface of the paper forms the curved surface of the cylinder.Learn more about 3D Shapes after Rotation here:

To solve this word problem, set up the equation (1/5) x + (1/10) x = 42 and solve for x. The team scored 140 points.
Explanation:To solve this word problem, we can start by letting the total number of points scored by the team be represented by 'x'. Since Michaela scored one-fifth of the team's points, her score can be represented as (1/5)x. Similarly, Aleah's score can be represented as (1/10)x. Together, their scores add up to 42 points, so we can set up the equation:
(1/5)x + (1/10)x = 42
To simplify the equation, we can find a common denominator of 10:
(2/10) x + (1/10) x = 42
Combining like terms, we get:
(3/10) x = 42
To isolate x, we can multiply both sides of the equation by 10/3:
x = 42 * (10/3)
Simplifying further, we get:
x = 140
Therefore, the team scored 140 points.

The following sequence is an arithmetic sequence what comes next ? 7,___,17
Since this is an arithmetic sequence, you can conclude that the addition to the number is constant.
Let x = the number asked
k = constant number added to the sequence
7 + k = x
x + k = 17
Solve the system of equation:
7 + k + k = 17
7 + 2k = 17
2k = 10
k = 5
Therefore, the missing number is 12 (7 + 5).
A person invested $7,200 in an account growing rate allowing money to double every 8 years. How much money would be in the account after 19 years, to the nearest dollar?
After 19 years, the final amount is $29,936.93, to the nearest dollar.
What is the formula for exponential growth?The formula for exponential growth:
[tex]final amount = initial amount * (rate)^(number of time periods)[/tex]
In this case, the initial amount is $7,200, the rate is 2 (since the money doubles every 8 years), and the number of time periods is 19/8=2.375 (since 19 years is 2.375 times the 8-year doubling period). Plugging these values into the formula, we get:
final amount = $7,200 * 2^2.375
The final amount is $29,936.93, to the nearest dollar.

Your friend wants to borrow $1,137.45 from you to pay off a credit card that charges a 14.7% APR. You agree to the loan but require your friend to pay you interest of 3.6% APR on the loan and your friend agrees.
Your friend pays you $200.00 at the end of the first month. How much goes toward the principal?
The amount that goes into the principal when friend pays you $200.00 at the end of the first month is $296.56.
How to calculate the amount?The first interest will be:
= 1137.45 × (0.036/12)
= 3.41
The amount owed at the month end will be:
= 1137.45 + 3.41
= 1140.86
The new balance after 200 payment will be:
= 1140.86 - 200
= 940.86
Therefore, the reduction in principal will be:
= 1137.45 - 940.86
= 196.59

Choose the correct product of (7x − 3)(7x + 3). 49x2 + 9 49x2 − 42x + 9 49x2 − 9 49x2 + 42x + 9
Final answer:
The product of the binomials (7x - 3)(7x + 3) is calculated using the difference of squares formula, resulting in 49x² - 9.
Explanation:
To find the correct product of the binomials (7x − 3)(7x + 3), we use the difference of squares formula, a² - b² = (a - b)(a + b). In this case, a is 7x and b is 3. Thus, the product is:
(7x − 3)(7x + 3) = (7x)² - (3)²
= 49x² - 9
Therefore, the correct product is 49x² - 9.

The population of wild horses on a wildlife refuge decreased from 110 to 99 in a year. If this trend were to continue, what exponential equation could be used to predict the horse population in the future?
y = 110(1.1)^x
y = 99(0.9)^x
y = 99(1.1)^x
y = 110(0.9)^x,
The exponential equation for this situation is y = 110(0.9) ^x. This is because 110 is the principal or the initial number of horses and y is the resultant population after a certain number of years X with a rate of 0.9. Note that the rate is less than 1 which means that the population is decreasing as time goes by.

Calculate the difference 12.0875 – 7.50 using significant digits.
A. 4.5
B. 4.587
C. 4.59
D. 4.6
C. 4.59
Step-by-step explanation:Significant digits are digits expressing precision of a measurement. Non-zero digits are always significant but zeroes can be either included or ignored. For instance, zeroes that comes before other digits aren't significant. For example 0.058 has two significant digits. In this exercise, we have two numbers:
12.0875
7.50
The number 12.0875 has five significant digits while 7.50 has three significant digits. If we add or subtract two numbers, the least number of decimal places (that isn't the same as significant digits) in any of the two numbers must be the same as the number of decimal places in the result. Hence, for 12.0875 we have four decimal places and for 7.50 we have two decimal places. Therefore, the result must have two decimal places:
12.0875 - 7.50 = 4.59
