Actually Welcome to the Concept of the linear equations.

so we solve here as,

==> -4(-2y+3)=20

==> 8y -12 = 20

==> 8y = 20+12

==> 8y = 32

==> y = 4

hence value of y = 4 .

Answer:

  t = ±√3

Step-by-step explanation:

The first equation tells us ...

  x^2 +tx +2 = (x -h)(x -k)

 x^2 +tx +2 = x^2 -(h+k)x +hk

Comparing coefficients, we have the equations ...

  t=-(h+k)

  2 = hk

__

The second equation tells us ...

  2x^2 +mx +2m = 2(x -h/k)(x -k/h)

  2x^2 +mx +2m = 2x^2 -2(h/k +k/h)x +2

Comparing coefficients, we have the equations ...

  m = -2(h/k +k/h)

  2m = 2

__

Dividing the last equation by 2 gives ...

  m = 1

Using that in the third equation, we have ...

  1 = -2(h/k +k/h) = -2(h^2 +k^2)/hk

Using hk = 2, this gives us ...

  h^2 +k^2 = -1

From the first equation, we know ...

  t^2 = (-(h+k))^2 = h^2 +2hk +k^2 = (h^2 +k^2) +2(hk)

Substituting the values for these terms, we have ...

  t^2 = -1 + 2(2) = 3

  t = ±√3

Possible values of t are √3 and -√3.

Answer:

it would be -1, 4

-1 x 5 = -5 and 2 x 4 = 8 so -5 + 8  = 3

-1 x 3 = -3 and 2 x 4 = 8 so -3 + 8 = 5

The minimum number of degrees in the rotation such that the hexagon will coincide with itself is 60°

Hexagons are six-sided polygons in geometry. A hexagon is said to be a regular hexagon if all of its sides and angles have identical lengths. To put it another way, a regular hexagon's sides are congruent.

Given that, Around its center, a regular hexagon is rotated counterclockwise.

We are aware that a hexagon has six sides.

There are also 360 degrees.

According to the data given, the calculation is as follows:

= 360 /60

= 60 degrees.

Therefore, we may say that the rotation must be at least 60 degrees in total.

Answer:

The correct answer is B

Step-by-step explanation:

-3,-4

Coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

" Clockwise rotation means when any object is moving in the direction of hands of clock."

According to the question,

As per the diagram ,

Coordinates of M are ( 3, 4)

Rotation of a point through 180° about the origin when a point M( x, y) is rotated about the origin through 180° in anticlockwise or clockwise direction, it takes the new coordinates ( -x ,-y).

Therefore , coordinates of M are ( -3, -4).

Hence, coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

Answer:

(x+2)(x-2)

Step-by-step explanation

x times x equals x^2, 2 times x equals 2x, -2 times x equals -2x, and 2 times -2 equals -4. If you add that up, the x-values cancel out, leaving the x^2 and the -4. (This explanation is working it backwards which is the easiest way IMO)

Answer:

f (8) = ( -161 )

Step-by-step explanation:

To find f(8) sub 8 for x in the equation and simplify:

[tex]f(8)=-3(8^{2} )+3(8)+7[/tex]

= -192 + 24 + 7

= -168 + 7

Question: y = 3cos[6(x-4)] - 5

Answer: 3

Step-by-step explanation:

The reason for this is in order to find amplitude, it's always the number before "cos" or "sin". Also, the "[6(x-4)]" was just a distraction to throw you off

Here's a trick to find everything; amplitude, period, phase sift, etc.:

      y = A sin(B(x + C)) + D

* amplitude is A

* period is 2π/B

* phase shift is C (positive is to the left)

* vertical shift is D
