Answer:

Yes. x = 30 is a solution for 120 = 4x

Step-by-step explanation:

If x is 30 you substitute the X next to the four for 30 that means you multiply 30 x 4 and you get 120 so X does equal 30

Help me I beg u! The pre-image coordinates of a triangle are J(-6,9), K(-6,4), and L(-3,4). The coordinates of the transformed t

Elena-2011 [213]

Answer:

A. Translation

Step-by-step explanation:

Given

Preimage

$J = (-6,9)$

$K = (-6,4)$

$L = (-3,4)$

Image

$J' = (2,9)$

$K' = (2,4)$

$L' = (5,4)$

Required

Which transformation occurred

The transformation that occurs is translation because each of the preimage were translated or shifter right by 8 units.

The rule applied here is:

$(x,y)=>(x+8,y)$

So, we have:

$J = (-6,9)$ $==> (-6+8,9) = (2,9)$

$K = (-6,4)$ $==> (-6+8,4) = (2,4)$

$L = (-3,4)$ $==> (-3+8,4) = (5,4)$

<em>Hence, the transformation is (a) Translation</em>

3x-4>11 solve and graph if possible

gavmur [86]

Answer:

3x−4>11

Step 1: Add 4 to both sides.

3x−4+4>11+4

3x>15

Step 2: Divide both sides by 3.

$\frac{3x}{3}$ > $\frac{15}{3}$

x>5
