Answer:
h=7
Step-by-step explanation:
We want to solve the equation:
We multiply through by the LCM:
Simplify to get:
We expand to get:
h=7
ΔMNO was dilated, then _____________, to create ΔYHQ.
2 answers:
Rotated
<h2>Explanation:</h2>Remember you have to write complete questions in order to find good and exact answer. So in this case I'll provide a general explanation and say that the blank can be filled with the word rotated. First of all, when dilating objects we reduce or enlarge the size of them. It's important to know the scale factor because this tells use whether the object will be larger or smaller, so if we call the scale factor, then:
- If k > 0 then the object will be larger than the original.
- If k < 0 then the object will be smaller than the original.
Moreover, the center of dilation is the point where all the lines that meet corresponding points of the original and dilated figure.
On the other hand, to rotate a shape we turn it about a fixed point that we call the center of rotation. So, in this case we'll have that ΔMNO is similar to ΔYHQ.

We need to find the image of the vector
We know that exists a matrix A from (because of how T was defined) such that :
for all x ∈
We can find the matrix A by applying T to a base of the domain ().
Notice that we have that data :
{
}
Being the cannonic base of
The following step is to put the images from the vectors of the base into the columns of the new matrix A :
(Data of the problem)
(Data of the problem)
Writing the matrix A :
Now with the matrix A we can find the image of such as :
⇒
We found out that the image of through T is the vector
