Answer:
B. 180°
Step-by-step explanation:
Rotate AB 180 degrees in the clockwise direction.
As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
3. 5x5x5. i am not sure if i am correct but i am assuming it is that.
Answer:
the first one that looks like a star
Step-by-step explanation:
because the shape on the base is a pentagon for the pyramid, and look for another pentagon in the middle of the images in the anwser choice and you find the first one is correct
Answer:
Step-by-step explanation:
We have two points
(
6
,
8
)
and
(
−
2
,
0
)
Explanation:
To find number of points of intersection, we should solve these pair of equations.
As
y
=
x
+
2
, we have
2
x
2
−
(
x
+
2
)
2
=
8
or
2
x
2
−
x
2
−
4
x
−
4
=
8
or
x
2
−
4
x
−

=

or
x

+
2
x
−

x
−
12
=
0
or
x
(
x
+
2
)
−
6
(
x
+
2
)
=
0
or
(
x
−
6
)
(
x
+
2
)
=
0
and hence
x
=
6
or
−
2
putting these values in
y
=
x
+
2
, we get
y
=
8
or
0
Hence, we have two points
(
6
,
8
)
and
(
−
2
,
0
)
