Mathematics
1 answer:
Dominik [7]3 years ago
7 0

Answer:

x : -3

Step-by-step explanation:

1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)

2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)

3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)

4) -6x = 18 (divide the -6 on both sides)

5) x = -3

lyudmila [28]

\\ \rm\hookrightarrow \sqrt{x-6}=x-12

\\ \rm\hookrightarrow x-6=(x-12)^2

\\ \rm\hookrightarrow x-6=x^2-24x+144

\\ \rm\hookrightarrow x^2-25x+150=0

\\ \rm\hookrightarrow x^2-10x-15x+150=0

\\ \rm\hookrightarrow (x-10)(x-15)=0

\\ \rm\hookrightarrow x=15\:or \:10

What are the coordinates of its image, J'KL, if this
shtirl [24]

Answer:

J'(-15,10)\\\\K'(15,10)\\\\L'(0,-20)

Step-by-step explanation:

For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".

 Dilation is defined as a transformation in which the Image and the Pre-Image have the same shape, but different sizes.

If a figure is dilated by a scale factor "k" with respect to the origin, the rule is:

(x,y) → (kx,ky)

In this case, the vertices of the triangle JKL (the Pre-Image) are:

J(-3.2)\\\\K(3,2)\\\\L(0,-4)

Knowing that the scale factor is:

k=5

You get that the vertices of the triangle J'K'L' (Image), are:

J'=(5(-3),5(2))=(-15,10)\\\\K'=(5(3),5(2))=(15,10)\\\\L'=(5(0),5(-4))=(0,-20)
