The value of y from the diagram is 9
<h3>Similar shapes</h3>
From the given figure, the shapes are similar, using the similarity theorem of triangles, you ill have;
6/10 = y/15
Cross multiply
10y = 15* 10
10y = 90
y = 90/10
y = 9
Hence the value of y from the diagram is 9

Answer:
D. 
Step-by-step explanation:
we are given
Firstly, it is reflected over x-axis
we know that for reflection about x-axis , we can replace y as -y
we get
now, it is vertical shift up by 4 units
so, we can add 4 to y-value
we get
Answer:
x^2 -2x+1
Step-by-step explanation:
(x - 1 )(x - 1)
FOIL
first: x*x = x^2
Outer: -1x
inner: -1x
Last: -1*-1 = 1
Add these together
x^2 -1x-1x+1
x^2 -2x+1
