Answer:
complet the squares
(x^2+14x)+(y^2+12y)=-60
add negative and positive 1/2 of linear coefs inside parenthaees
14/2=7, 7^2=49
12/2=6, 6^2=36
(x^2+14x+49-49)+(y^2+12x+36-36)=-60
factor perfect square
((x+7)^2-49)+((y+6)^2-36)=-60
get rid of parnthaeses
(x+7)^2-49+(y+6)^2-36=-60
(x+7)^2+(y+6)^2-85=-60
add 85 to both sides
(x+7)^2+(y+6)^2=25

The value of the inverse function f⁻¹(x) at x = 3 is 0.631.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
The function f(x) = 3ˣ is a one-to-one function, which means it has an inverse function denoted by f⁻¹(x).
To find the value of f⁻¹(x) at x = 3, we need to solve the equation f(x) = 3ˣ = 3 for x.
3ˣ = 3
Divide both sides by 3:
3ˣ/3 = 3/3
Simplify:
3ˣ-1 = 1
Take the natural logarithm of both sides:
ln(3ˣ-1) = ln(1)
Simplify:
ln(3ˣ-1) = 0
Now we can solve for x:
ln(3ˣ-1) = 0
3ˣ-1 = e⁰ = 1
3ˣ = 2
x = log₃(2)
So, f⁻¹(3) = log₃(2) ≈ 0.631.
Therefore, the value of f⁻¹(x) at x = 3 is 0.631.

Step-by-step explanation:
What is the least possible positive integer-value of n such that sqrt{18\cdot n \cdot 34}$ is an integer?
Answers
Answer:
n = 17. This means, √(18 x 17 x 34) = √(10404) = 102.
Step-by-step explanation:
An integer is a number that is not a fraction.
Given √(18 x n x 34), for the expression to be an integer, the product must be a perfect square. We are looking for n, the smallest number to multiply 18 x 34 to make it a perfect square. We have:
18 x 34 = 2 x 9 x 2 x 17 = 2 x 3 x 3 x 2 x 17 = 2² x 3² x 17.
From here, we see that we need to multiply an extra 17 to make it a perfect square, therefore n = 17. So we have:
√(18 x 17 x 34) = √(10404) = 102
The least possible positive integer-value of n such that [tex]\sqrt{18\cdot n \cdot 34}[/tex] is an integer is 17
The expression is given as:
[tex]\sqrt{18\cdot n \cdot 34}[/tex]
Expand the equation
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 9 \times n \times 2 \times 17}[/tex]
Express 8 as 3^2
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 3^2 \times n \times 2 \times 17}[/tex]
Rearrange the factors as follows:
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2 \times 2\times 3^2 \times n \times 17}[/tex]
Express 2 * 2 as 2^2
[tex]\sqrt{18\cdot n \cdot 34} = \sqrt{2^2\times 3^2 \times n \times 17}[/tex]
Evaluate all exponents
[tex]\sqrt{18\cdot n \cdot 34} = 2\times 3 \times \sqrt{n \times 17}[/tex]
[tex]\sqrt{18\cdot n \cdot 34} = 6 \times \sqrt{n \times 17}[/tex]
For the expression to be an integer, then the radical must be a perfect square.
Given that the expression in the radical is [tex]{n \times 17[/tex], then the value of n must equal 17, at the very least
i.e.
[tex]n = 17[/tex]
Hence, the least possible positive integer-value of n is 17

Answers
Answer: Choice C) 6x+5y = -20
You have the correct answer. Nice work.
=================================================
Work Shown:
y = (-6/5)x - 4
5y = 5*( (-6/5)x - 4 )
5y = 5*(-6/5)x - 5*4
5y = -6x - 20
6x+5y = -20
-----------
Explanation:
In the second step, I multiplied both sides by 5 to clear out the denominator. Two steps later (step 4), we have 5*(-6/5)x turn into -6x, so the fraction goes away.
In the last step, I added 6x to both sides to get the equation into standard form Ax+By = C. In this case, A = 6, B = 5, and C = -20.
