Answer:

See explanation

Step-by-step explanation:

You forgot to give the coordinates of C.

Note that, the mapping for 90° clockwise rotation around the origin is given by:

(x,y)\to (-y,x)

Assuming the coordinates of C were (-6,6), then the coordinates of C after a 90° clockwise rotation

around the origin is (-6,-6)

The coordinates of the midpoint of GH are M(-2, 0), and the coordinates of one endpoint are H(4,-4).
Svetlanka [38]

The coordinate of point S from the giving coordinate point is (-8,4)

<h3>Midpoint of coordinates</h3>

The formula for calculating the midpoint of coordinate point is expressed as:

M(x,y) = {(x₁+x₂)/2, (y₁+y₂)/2}

Determine the measure of the coordinate S
-2 = 4+x₂/2

2(-2) = 4+x₂

x₂ = -4-4

x₂ = -8

Similarly

0 = -4+y₂/2

0(2) = -4+y₂

y₂ = 4

Hence the coordinate of point S from the giving coordinate point is (-8,4)

Which of the following equations is equivalent to 2log4x − log49 = 2?
Masja [62]

Answer:

The value of x for given log equation is 17. 5

Step-by-step explanation:

Given as :

The log function is

2 log 4 x - log 49 = 2

Or, 2 log 4 x - log (7 × 7) = 2

Or, 2 log 4 x - log 7² = 2

<u>from Log property</u>

Loga^{b} = b Log a

So, 2 log 4 x - 2 log 7 = 2

Taking 2 from Left hand side of equation

Or, 2 × (log 4 x - log 7) = 2

Or, (log 4 x - log 7) = \dfrac{2}{2}

Or, (log 4 x - log 7) = 1

<u>Again from Log property</u>

Log m - Log n = Log \dfrac{m}{n}

So, (log 4 x - log 7) = 1

Or,  Log \dfrac{4 x}{7} = 1

Now,<u> Taking anti Log , we get</u>

So, \dfrac{4 x}{7} = antilog 1

i.e \dfrac{4 x}{7} = 10^{1}

Or, 4 × x = 10 × 7

∴  x = \dfrac{70}{4}

Or, x = 17.5

So, The value of x = 17.5

Hence, The value of x for given log equation is 17. 5  Answer
