Can someone please explain to me how I’m suppose to solve it?

Answer:

1. x = 9

2. (10, -4)

4. (-4, -6)

5. (4, -1)

Step-by-step explanation:

1. Since we know that y = 3x + 27, we can substitute that into y = 4x + 18.

3x + 27 = 4x + 18

9 = x

x = 9

Continue the processes of setting both equations of a system to a specific value, and then substituting it into the other equation.

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.

The selling price of a used book at the store where the owner buys a used book for $1.50 and resells the used book at a price of 400% the price at which buys the used book is $6.00

The selling price of an item is the price which is displayed on the item on the shelves of a store. The selling price is often different from the price at which the item is bought, or produced, which is often lesser than the price at which the item is sold.

The amount at which the owner buys each used book = $1.50

The amount at which the owner of the used book store sells the books = 400% of the amount he paid for the books

400% of an amount x is equivalent to four times the amount. (4 × x)

The price at which the owner sells a used book at his store, P, is therefore;

P = 400% × $1.50 = 400/100 × $1.50 = $6.00

The price of a used book at the store is $6.0

The area of something like a rectangle with a length of 8 units and a diagonal of 11 units is 60.396.

A diagonal in mathematics is a line that joins two vertices of a solid or polygon whose vertices seem to be not on the same edge. Generally general, a diagonal is a sloping or slanting line that joins the vertices of a form. Diagonals are lateral shapes with sides, edges, and corners.

Length = 8

Diagonal = 11

A=w l

D = √(w² + l²)

Area  = l√(d²- l²)

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.

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

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
