Answer:

4th quadrant

Step-by-step explanation:

The real part, +6, is positive, and so this number must be in either the 1st or the 4th quadrant. The imaginary part, -8i, is neg., so the number must be in either the 3rd or the 4th quadrant. Summing up, 6 - 8i must be in the 4th quadrant.

Answer:

4th quadrant

Step-by-step explanation:

A complex number Z = A + Bi can be represented in the same way like we represent a point (a,b) in the coordinate plane.

Like in two dimensional coordinate system where there is X axis and Y Axis In complex plane , for locating real part of complex number we use X axis and for locating imaginary part we use Y axis.

So Complex number Z= 6 - 8 i = Point in the complex plane (6,-8)

6 = Real Part = Positive real number

-8 = Imaginary Part = Negative real number

Point (6,-8) will lie in Fourth Quadrant.

The smallest square number which can be divisible by 11 and 5

Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

$\sqrt{55x} = \sqrt{5 \times 11 \times x}$

the smallest value of x to make 55x a perfect square is....

$x = 11 \times 5 = 55$

Therefore the number is.... .

$55x = 55(55) = 3025$

sweet right

Pleas someone help me with this it's my last question

ruslelena [56]

Answer:

we need to find out if the following get x = 2 as a final product

-2(x-4) = 4

-2x + 8 = 4

-2x = -4

x = 2

so it is a solution

26/x = 13

26 = 13x

x = 26/13

x = 2

so it’s a solution

-3.8x = -7.4

x = 7.4/3.8 ≠ 2

you get ≈ 1.95

so it’s not a solution

4(x-1) - 3(x-2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -10

so it’s not a solution

Which points define the solution set

Lemur [1.5K]

There is a line and a parabola in the graph.

So, we will get the solution set from the point of intersection of both line and parabola.

Notice that the parabola and the line intersecting at two points E(1, 5) and C(-0.5,2).

So, the solution set is E(1, 5) and C(-0.5,2).
