Answer:
D. (7, 0)
Step-by-step explanation:
The rule for a reflection over the y-axis is (x, y) → (x, -y)
This means that the x-values stay the same while the y-values change.
Q(x, y) → (x, -y)
Q(3, 0) → (3, 0)
Q'(3, 0)
P(x, y) → (x, -y)
P(5, 6) → (5, -6)
P'(5, -6)
R(x, y) → (x, -y)
R(7, 0) → (7, 0)
R'(7, 0)
Therefore, the correct answer is D.
Hope this helps!
A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure.
There are 12 inches in one foot:
1 ft = 12 in
We want to find how many feet are in 5000 inches:
x ft = 5000 in
Set up a proportion:
1/12 = x/5000
Cross multiply:
12x = 5000
Divide by 12:
x is about 416.67 feet.
It would be false because 879 will be rounded up to 880 or 900.
Answer:
-3a^3 + 2a.
Step-by-step explanation:
21a3 − 14a / -7
= 21a^3 / -7 - 14a / -7
= -3a^3 + 2a.
