Neither of the ordered pairs is a solution of the equation 6x + 3y = 15.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given linear equation is 6x + 3y = 15

Substitute each of the point given in the options.

A : (3, -2)

6x + 3y = (6 × 3) + (3 × -2) = 18 - 6 = 12 ≠ 15

B : (2, 2)

6x + 3y = (6 × 2) + (3 × 2) = 12 + 6 = 18 ≠ 15

Neither (3, -2) nor (2, 2) are the solutions of the equation.

Hence neither is the solution of the given linear equation.

If we put the number of sticks in a sequence we get:

As we see the difference of the terms is common and is 4, and the first term is 6. It is therefore an arithmetic progression with:

Use the nth term equation:

Substitute n = 6 to find the number of sticks of the 6th term:

Find the nth term:

Answer:  We can use the concept of rates to solve this problem.

A rate is a ratio of the amount of work done to the amount of time it takes to do the work. We can find the rate of work for the 4 painters by dividing the number of rooms they painted by the number of hours it took them:

Rate = Rooms painted / Hours

Rate = 12 rooms / 8 hours = 1.5 rooms per hour

Now we can use this rate to find out how long it will take 7 painters to paint 21 rooms. To do this, we'll use the formula:

Time = Rooms / Rate

Time = 21 rooms / 1.5 rooms per hour = 14 hours

So it would take 7 painters working at the same efficiency as the 4 painters 14 hours to paint 21 rooms.

Step-by-step explanation:

The length of diagonal of a parallelogram is 2546 inches.

A quadrilateral with equal pairs of opposing sides and angles is referred to as a parallelogram. It has a pair of opposing sides that are parallel to one another. The inner angles are supplementary in nature, meaning that the sum of them equals 180 degrees. A parallelogram's diagonals are bisected by one another, or divided into two equal portions. A parallelogram's internal angles add up to 360 degrees.

The diagonals of parallelogram are given by:

x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)

Given the two sides are 35 and 75 inches.

We also know that the adjacent angles of parallelogram are supplementary:

∠A + ∠B = 180

140 + ∠B = 180

∠B = 40

Substitute the value of sides and angle in the equation:

x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)

x = √((35)^2 + (72)^2 + 2(35)(72) cos 140)

x = 1225 + 5184 + (5040)(-0.766)

x = 1225 + 5184 - 3860

x = 2546 inches

Hence, the length of diagonal is 2546 inches.

Interest of 3% a year of principal of 200,000 = 6000

monthly payment of 843 also includes a portion of amortization of the principal itself, which you can ignore cause the question only asked for the interest portion.

this is an unclear question cause it didn't say PER YEAR interest paid.  you only need to remember interest% * principal = ANNUAL interest payment $.  Then you can divide that over 12 months, which is 500$ per month.

The numerical value of x in the expression 5x - 7 is 7.65.

A square is simply a 2-dimentional plane figure with four equal sides and four right (90°) angles.

The perimeter of the square is the sum of the length of all four sides of the square.

P = 4l

Given the data in the question

To find the value of x, plug the given values into the above equation and simplify.

P = 4l

125 = 4( 5x - 7 )

125 = 20x - 28

When T = -7; n = 1

⇒ -7 = a(1)² +b (1) +6

⇒ a + b + c=-7 -----------1

At n=2, T₂ = 0

If Lilyana runs a cake decorating business for which 10% of her orders come over telephone , then probability that it takes fewer than 5 orders for Lilyana to get her first telephone is 0.3439  .

The geometric distribution is used to calculate the required probability ,

In this case, the success is a telephone order, and

the failure is an order placed in some other way.

Let probability of success is ⇒ p , and

let the number of orders needed to get the first telephone order be = x . Then, X follows a geometric distribution with parameter p, so we have:

Probability of P(X = k) is = (1-p)^(k-1) × p ;

where k is the number of orders needed.

the probability of success (p) is  = 10% = 0.1

we have to find the probability that it takes fewer than 5 orders for Lilyana to get her first telephone order of the month.

that means : P(X<5) = P(X=1) + P(X=2) + P(X=3) + P(X=4)

Substituting the values of p = 0.1 ,

we get ;

= (1-0.1)⁰ × 0.1 + (1-0.1)¹ × 0.1 + (1-0.1)² × 0.1 + (1-0.1)³ × 0.1

Simplifying further ,

we get ;

= 0.1 + 0.09 + 0.081 + 0.0729

The table which matches the equation and includes only viable solutions is the third table.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side

Given that equation is,

c = 3.5b

Here b is the number of loaves of bread and c is the total cost of the bread.

All the table values matches the equation when we substitute the value of b and c in the equation.

But number of loaves of bread cannot be fractions or negative numbers.

So the most viable solution is the third table consisting of values of b as  0, 3, 6, 9 and corresponding value of c as 0, 10.5, 21, 31.5.

Hence the 2-column table with the first column labeled loaves (b) with entries 0, 3, 6, 9 and the second column labeled cost (c) with entries 0, 10.5, 21, 31.5 is the correct one.

Meaning of a sequence:

A grouping of any objects or a collection of numbers in a particular order that follows some rule is known as a sequence.

The difference between all the following terms in the sequence 10..6.11.8.13 is 12.

As a result, the series is an example of a linear function.

The length of Jane's shadow is approximately 2.85 feet

To find the length of Jane's shadow, we can use the principle of similar triangles.

The ratio of the shadow length to the object height is the same for both King Neptune and Jane, then we can set up a proportion:

(shadow length of King Neptune) / (height of King Neptune) = (shadow length of Jane) / (height of Jane)

Given that King Neptune's shadow is 3 13 5 feet and the statue is 34 feet tall.

By substituting these values into the proportion:

(3 13 5 feet) / (34 feet) = (shadow length of Jane) / (5' 9")

To find the shadow length of Jane, we can cross-multiply and solve for the shadow length:

(3 13 5 feet) * (5' 9") = (shadow length of Jane) * (34 feet)

Converting Jane's height into feet: 5'9" = 5*12 +9 = 69 inches = 5.75 ft

(3 13 5 feet) * (5.75 ft) = (shadow length of Jane) * (34 feet)

shadow length of Jane = (313.5*5.75) / 34 = 2.85 ft
