Answer:

Step-by-step explanation

In these type of questions we can use a trick to find answer

let's say we have two linear equation

1) ax+by+c=0

2)mx+ny+t=0

if  a/m = b/e ≠ c/f  that means we don't have any solution for these two equations ( that's because of analitic geometry)

so,

2x-ky-14=0

5x-2y-5=0

If k is 4/5, the system of equations will have no solution because the lines are parallel.

Two or more expressions with an Equal sign is called as Equation.

The system will have no solution if the two equations represent parallel lines, because parallel lines do not intersect.

To determine if the lines are parallel, we can compare the slopes of the two lines.

The slope of the first line is 2, since it is the coefficient of x when we solve for y:

2x - ky = 14

ky = 2x - 14

y = (2/k)x - 14/k

The slope of the second line is 5/2, since it is the coefficient of x when we solve for y:

5x - 2y = 5

2y = 5x - 5

y = (5/2)x - 5/2

Therefore, the two lines are parallel if the slopes are equal:

2/k = 5/2

4 = 5k

k = 4/5

So, if k = 4/5, the system of equations will have no solution because the lines are parallel.

Area of a circle is pi times r-square

[tex]\pi \: {r}^{2} [/tex]

So...

[tex] \frac{22}{7} \times \frac{21}{2} \times \frac{21}{2} = \frac{22 \times {21}^{2} }{28} [/tex]

Explanation:

Point C is located at (-6,3). The x coordinate is x = -6.

Going from x = -6 to x = -1 is 5 units to the right. We move another 5 units to the right to go from x = -1 to x = 4 when arriving at its reflected location (4,3). The y coordinate stays the same the entire time.

It might help to refer to the diagram below.

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

let the number be 'x'

95 % of x = 38

(95 / 100)x =38

x = 38 × 100 / 95

x = 2 × 100 / 5

x = 2 × 20

x = 40

Answer:

the answer for this question is 5.51

Answer:

x = 18°

Step-by-step explanation:

∠AOB and ∠BOD form linear pair of angles, so they are supplementary, i.e., their sum is 180°.

130° + (2x + 14)° = 180°

=> 130° + 2x° + 14° = 180°

=> 2x° = 180° - 130° - 14°

=> 2x° = 36°

=> x = 36°/2°

=> x = 18°

None of the above.

It is a complex number.  The sqrt(-9) is defined as 3i.

i is a definition brought into existence to represent the square root of -1. There is nothing at this level of math that you can point to and say this is the physical thing that is the square root (-1). It is just a math/physics definition.

Answer:

It is Tn = 9n - 11

Step-by-step explanation:

It is an arithmetic progression:

[tex]T_{n} = a + (n - 1)d[/tex]

a is the first term, a = -2

n is number of terms

d is common difference, d = 7-(-2) = 9

[tex]T_{n} = - 2 + \{ (n - 1) \times 9 \} \\ T_{n} = - 2 + 9n - 9 \\ T_{n} = - 11 + 9n \\ T_{n} = 9n - 11[/tex]

Answer:

[tex]T_{n}[/tex] = 9n - 11

Step-by-step explanation:

There is a common difference between consecutive terms, that is

7 - (- 2) = 16 - 7 = 9

This indicates the sequence is arithmetic with nth term

[tex]T_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 2 and d = 9 , then

[tex]T_{n}[/tex] = - 2 + 9(n - 1) = - 2 + 9n - 9 = 9n - 11
