Answer: To prove that AB is parallel to DC, we can use the following steps:

Draw a diagram of the cyclic quadrilateral ABCD with the point E where sides AD and BC are produced to meet.

Since ABCD is a cyclic quadrilateral, all its interior angles add up to 360 degrees. Therefore, angle A + angle B + angle C + angle D = 360 degrees.

Since AE = BE, we can say that angles A and B are equal (by corresponding angles). Similarly, angles C and D are also equal.

Since angles A and B are equal and angles C and D are also equal, we can say that angle A + angle B = angle C + angle D.

Substituting this into our equation from step 2, we get: angle A + angle B + angle C + angle D = angle A + angle B + angle A + angle B.

Simplifying, we get: 360 = 2(angle A + angle B). This means that angle A + angle B = 180.

Since angle A + angle B = 180, we can say that angle A = angle B and angle C = angle D.

Now we can use the fact that corresponding angles are equal, then angle A = angle C and angle B = angle D.

We know that opposite angles of a parallelogram are equal, so we have proved that AB is parallel to DC.

It's important to note that this proof uses the fact that quadrilateral ABCD is cyclic, which means that the sum of its angles is equal to 360 degrees. It also uses the fact that opposite angles are equal in a parallelogram, and corresponding angles are equal when two lines are parallel.

Step-by-step explanation:

The function f(x)=2x-3 is not surjective.

The surjective function is defined with reference to the elements of the range set, such that every element of the range is a co-domain.

A surjective function is a function whose image is equal to its co-domain, and every element y can be mapped from element x so that f(x) = y.

it suffices to give an example of y∈Z such that f(x)=y has no solutions. Just pick y=−2 and derive that

f(x)=−2⟺2x−3=−2⟺2x=1

and it should be quite clear that this has the unique solution x=0.5 over Q so no solutions for Z.

The pair of linear equations y = 0 and y = -7 have no solution.

Given the pair of equations is

y = 0

y = -7

We have to find a solution.

Here, b₁ = 1, c₁ = 0

b₂ = 1, c₂ = -7

So, b₁/b₂ = 1/1 = 1

c₁/c₂ = 0/-7 = 0

So, b₁/b₂ ≠ c₁/c₂

We know that,

Let's assume a pair of linear equations in two variables be a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0,

If a₁/a₂ = b₁/b₂ ≠ c₁/c₂, then

i) the given pair of linear equations is inconsistent

ii) the graph will be a pair of parallel lines, so the pair of equations will have no solution.

The length of the diagonal KM is 8√(2) inches.

The area of a square is given by the formula: area = side^2.

So, if the area of square JKLM is 64 square inches, then we know that:

64 = side^2

To find the diagonal KM, we can use the Pythagorean Theorem. The diagonal KM is the hypotenuse of a right triangle where the legs are the side of the square.

So the formula is KM = √(side^2 + side^2)

Substituting in the known area of the square, we have:

KM = √(64 + 64)

KM = √(128)

KM = 8√(2)

Therefore, the length of the diagonal KM is 8√(2) inches.

The annual interest rate on the loan is 0.02 or 2%.

To find the annual interest rate on the loan, we need to use the formula for simple interest:

I = Prt

where:

I is the interest,

P is the principal (the amount of the loan),

r is the annual interest rate (expressed as a decimal),

t is the time in years

We know the following information:

I = $240

P = $4000

t = 3

We can use this information to set up the equation and solve for r:

240 = 4000 * r * 3

240 = 12000r

r = 240/12000

r = 0.02

Therefore, the annual interest rate on the loan is 0.02 or 2%.

Answer: The given trinomial, 24ab-16a^2-9b^2, can be written as an expression opposite to a square of a binomial.

To do this, we first factor out the greatest common factor of -4a, which gives us:

-4a(6b-4a-9b^2)

We can then factor -9b^2 as -(3b)^2, and group the remaining terms together:

-4a((3b-2a)^2-4a^2)

So the trinomial can be written as -4a( (3b-2a)^2 - 4a^2 ) which is an expression opposite to a square of a binomial (3b-2a)^2.
