Answer:

X=7 and y=6

Step-by-step explanation:

Y=-2x + 20.......eq(i)

6x-5y=12.....eq(ii)

Now, putting y= - 2x +20 in eq (ii)

6x - 5(-2x + 20)=12

6x + 10x - 100 = 12

16x=12+100

X=112 /16

X=7

Then, putting x=7 in eq (i)

Y=-2*7 +20

=-14 +20

Find the exact value of : cos(2 arctan(4/3))

QveST [7]

Cos(2 arctan(4/3)) = cos(2 arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arccos(3/5)) = cos^2(arccos(3/5)) - sin^2(arcsin(4/5)) = (3/5)^2 - (4/5)^2 = 9/25 - 16/25 = -7/25.

The first hexagon which is 5 is dilated to form the second hexagon which is 6.25

pshichka [43]

ANSWER
Scale factor is 1.25

The dilation is an enlargement.

EXPLANATION

Let the scale factor of the dilation be k, then

$5 \times k = 6.25$

We divide both sides by 5 to get,

$k = \frac{6.25}{5}$

This implies that,

$k = 1.25$

Since the scale factor is more than one, the dilation is an enlargement.
