lim x tends infinity, (2/3)^x = ?
The limit lim x → ∞ (2/3)ˣ = ∞
What are limits?A limit is the value of a function as the independent variable tends to a particular value.
How to find the given limit?Since we have lim x → ∞ (2/3)ˣ, to find this limit, using the fact that lim x → a ㏑f(x) = ㏑[lim x → a ㏑f(x) ]
So, since lim x → ∞ (2/3)ˣ, taking natural logarithm of both sides, we have that
lim x → ∞ (2/3)ˣ
㏑[lim x → ∞ (2/3)ˣ] = lim x → ∞ ㏑(2/3)ˣ
= lim x → ∞ x㏑(2/3)
So, substituting x = ∞ into the equation, we have that
lim x → ∞ x㏑(2/3) = ∞㏑(2/3)

prove that there is a 1-1 correspondence between the set of all positive integers and the set of all rational numbers
A one-to-one correspondence between the set of all positive integers and the set of all rational numbers exists.
By definition, any rational number can be expressed as a fraction a/b, where a and b are integers and b is nonzero. Since any positive integer can be expressed as the fraction a/1, each positive integer can be associated with a rational number a/1.
Thus, there is a one-to-one correspondence between the set of all positive integers and the set of all rational numbers. Furthermore, since any rational number a/b can be expressed as the product of a and b, it can also be associated with the product of two positive integers a and b.
Thus, there is also a one-to-one correspondence between the set of all rational numbers and the set of all positive integers.

Solve the system of equations using elimination: 7x + 4y = -9 and

For the provided functions 7x + 4y = -9 and -5x - 3y = 7, the values of x and y are 1 and -4, respectively.
What is a linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Given the system of equations using elimination: 7x + 4y = -9 and
-5x - 3y = 7.
From equation 2
-5x - 3y = 7
calculate the value of x in the function of y
-5x = 7 + 3y
x = (-7 - 3y)/ 5
Substituting this value in equation 1
7/5(-7 - 3y) + 4y = -9
y = -4
substituting this value in equation 1
7x + 4(-4) = -9
x = 1
Therefore, the values of x and y the given functions 7x + 4y = -9 and

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (-3, -1) and (5, -1).
Now,
Since, The equation of line passes through the points (-3, -1) and (5, -1)
So, We need to find the slope of the line.

equation below where:
volume = v
circumference = c
V=
The volume of the balloon is 1441.64cm³.
How to calculate the volume?To calculate the volume these are few ways
Solve for Volume by space. All physical objects occupy space, and you can find the volume of some of them by measuring their physical dimensions. Solve for Volume by Density and Mass. Density is defined as an object's mass per a given unit of volume. Solve for Volume by Displacement.The radius of the balloon is given as 7 cm. Also, the equation to calculate the volume is given as c³/6π²
The circumference c will be:
= 2πr = 2 × 22/7 × 7
= 44
The volume will be:
= c³/6π²
= 44³/(6 × 3.14²)
= 85284/(59.1576)
= 1441.64

Answer:
multiply the second equation by -2(x, y) = (2, 2)Step-by-step explanation:
Apparently, you want to solve the system of equations by multiplying or dividing one of them by a factor that will make the y-coefficients the same.
MultiplicationThe y-coefficients are 2 and -1, so we can multiply the first by -1/2 to make it the same as the second, or we can multiply the second by -2 to make it the same as the first.
We prefer to work with integers, rather than fractions, so we choose to multiply the second equation by -2.
-2(3x -y) = -2(4)
-6x +2y = -8 . . . . . . . y-coefficient is the same as in the first equation
SolutionNow, we can subtract the second equation from the first to eliminate the y-terms:
(3x +2y) -(-6x +2y) = (10) -(-8)
9x = 18 . . . . . . . . . simplify
x = 2 . . . . . . . . . divide by 9
Substituting this into the original second equation gives ...
3(2) -y = 4
6 -4 = y = 2 . . . . . . . add (y-4)
The solution is (x, y) = (2, 2).
__
Additional comments
The picture posted here has no question, so there is no way to tell how to answer it. Any answer must be provided in accordance with whatever instructions are given.
Solving these equations is somewhat easier if you make the y-coefficients opposites, rather than the same. This can be done by multiplying the second equation by 2: 6x -2y = 8. Now the equations can be added to give 9x = 18, as above.
Of course, the x-coefficients are already the same, so we can more easily eliminate the x-terms. Subtracting the second equation from the first gives ... (3x +2y) -(3x -y) = (10) -(4), or 3y = 6.
