HELP 10PTS AND BRAINLIESTThe image of a triangle after it has been dilated with a center of dilation at the origin has vertices

Gala2k [10]

Answer:

C is (-18, 24)

Scale factor 1 1/3

A is (9, - 4 1/2) *4 1/2 is also 4.5

Step-by-step explanation:

When we take a look at image B (-24, -12) and pre image B (-18, -9),

we can work out the scale factor by

(-24/-18) and (-12/-9) both equal 4/3

So using the scale factor to go from the pre image to the image,

We can find C coordinate by multiplying pre image C by the scale factor.

C is (-13.5 x 4/3) and (18 x 4/3)

C is (-18, 24)

The scale factor is 4/3, which is the mixed numeral of 1 1/3.

To find the pre image of point A we divide the image by the scale factor

A is (12/(4/3)) and (-6/(4/3))

A is (9, - 4 1/2)

Hope this helps,

10.9 + (-15.6) + 2.1 write as a decimal

Delvig [45]

Answer:

-2.6

Step-by-step explanation:

10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6

Therefore the answer is -2.6

Y= 3x + 1

Alika [10]

Answer:

y= -11

Step-by-step explanation:

After rearranging equation 2, we get x= y+3/2

Sub it into equation 1

y= 3(y+3/2) + 1

y= 3y+9/2 + 1

y= 3y + 11 / 2

2y = 3y + 11

-y = 11

y = -11

HELP PLEASE I'LL MARK BRAINLEST!!

Jet001 [13]

Answer:

s = $\sqrt{60}$

Step-by-step explanation:

$A = s^{2}$

so:

$\sqrt{A} = \sqrt{s^2}$

$s = \sqrt{A}$

A = 60

Therefore:

s = $\sqrt{60}$

leva [86]

Answer:

6/7

Step-by-step explanation:

Product of slope of perpendicular line = -1

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\$

$= \frac{7-0}{3-9}\\\\=\frac{7}{-6}\\\\=\frac{-7}{6}$

Slope of the perpendicular line = -1/m = -1 ÷ $\frac{-7}{6}$

$= -1 * \frac{-6}{7} = \frac{6}{7}$
