You would combine like this:
17e=18
Then divide off the sides
17e/17e 18/17e which cross out the 17 e which leaves you with 1.1
Answer:
Slope: -3/2 y intercept: 3
Step-by-step explanation:
When (-5, 2) is reflected across the y-axis then it becomes (5, 2). When (-5, 2) is reflected across the x-axis, it becomes (-5, -2)
I hope this helps out!
Answer: It is a rectangle.
Step-by-step explanation: 2 rectangles of different sizes are being in top of each other.
Step-by-step explanation:
We must take our equation and put it in vertex form,
f
(
x
)
=
a
(
x
−
h
)
2
+
k
where
h
,
k
is our vertex.
This equation will not factor into two squares
(
x
−
h
)
2
so we must use the completing the square method.
First we'll get rid of the
3
by subtracting it giving
x
2
−
4
x
=
−
3
Next we take half of the -4 the square it and add it to our equation to give us
x
2
−
4
x
+
4
. Since we added
4
to the left, we must also add it to the right giving
x
2
−
4
x
+
4
=
+
4
−
3
.
Now we can factor the left into two perfect squares,
(
x
−
2
)
2
=
1
.
Finally, we subtract
1
from both sides giving
(
x
−
2
)
2
−
1
. Our vertex is
h
,
k
giving
2
,
−
1
