solve for y:
x^3 + (1/a)y= xy+9
Step-by-step explanation:
[tex] {x}^{3} + ( \frac{1}{a} )y = xy + 9[/tex]
[tex]x {}^{3} + \frac{y}{ay} = xy + 9[/tex]
[tex]x {}^{3 } = xy + 9 - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = xy - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = y(x - \frac{1}{a} )[/tex]
Divide both sides by x-1/a
[tex] \frac{x {}^{3} - 9}{x - \frac{1}{a} } = y[/tex]
When you round a number, what should you do with
the digits to the right of the place to which you
are rounding?
Answer:
In general, to round to a certain place value, look at the digit to the right of that place value and make a decision. Example: 5.1837 to the nearest hundredth would be 5.18 (round down since 3<5 ), but to the nearest thousandth, it is 5.184 (round up because 7≥5 ).

Find the value of x and
y if x-y=3 and 2x+3y=4
Answer:
Step-by-step explanation:
Given :
x-y = 3 equation(i)
2x + 3y = 4 equation(ii)
Now,
x - y = 3
x = 3 + y
substitute the value of x in equation (ii)
2x + 3y = 4
2(3 + y) + 3y = 4
6 + 2y + 3y = 4
6 + 5y = 4
y = -2/5

x is less than or equal to 3. What is the interval notation
Answer:
Step-by-step explanation:
Answer: Interval notation: (−∞, 3) ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: x<3 or x≥−1. x < 3 or x ≥ − 1. .
The statement in the mathematical form will be x ≤ 3. Then the inequality in the interval notation will be [3, ∞).
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
x is less than or equal to 3.
Convert the statement into a mathematical inequality. Then we have
x ≤ 3
The statement "x is less than or equal to 3" in the mathematical form will be x ≤ 3.
Thus, the inequality in the interval notation will be [3, ∞).

The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?
9514 1404 393
Answer:
1125
Step-by-step explanation:
The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.
$5.60n = $6300
n = 6300/5.6 = 1125
The company should sell 1125 units per month to break even.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n" ways; then the two events in succession can occur in m × n ways.
Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.
Pencil = 21
Pencil holder = 3
Therefore, we will do as 21 divided by 3
21/3 = 7
Hence, there are 7 pencils in each pencil holder.
