Answer: (A) The image of JKL after a 90° counterclockwise about the origin is shown in figure 1. (B) The image of JKL after a reflection across the y-axis is shown in figure 2.
Explanation:
(A)
From the given figure it is noticed that the coordinate points are J(-4,1), K(-4,-2) and L(-3,-1).
If a shape rotate 90 degree counterclockwise about the origin, then,




Therefore, the vertex of imare are J'(-1,-4), K'(2,-4) and L'(1,-3). The graph is shown in figure (1).
(B)
If a figure reflect across the y-axis then,




Therefore, the vertex of imare are J''(4,1), K''(2,-4) and L''(3,-1). The graph is shown in figure (2).

Answer: Choice B</h3>
Explanation:
The term "rising" will indicate that we should use positive 1/3 instead of negative 1/3.
Choices A and C use "decreasing" which is why they involve -1/3. This is why we can rule out these two choices.
Answer:
(-6, 36)
Step-by-step explanation:
The standard form: ax^2 + bx + c
In this case:
a is 1
b is 12
c is 0
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
-12 / ( 2 x 1 )
-12 / 2
-6
You log -6 in the function
f(x) = x^2 + 12x
f(-6) = (-6)^2 + 12(-6)
= 36 + (-72)
= 36 - 72
= 36

Answer:
A and D
Step-by-step explanation:
These dot plots show the ages (in years) for a sample of two types of fish. Wat are the differences between the centers and spreads of these distributions? Select two choices: one for the centers and one for the spreads.
A. Centers: The sharks have a lower median age than the koi.
B. Spreads: The ages of the sharks are more spread out.
C. Centers: The sharks have a greater median age than the koi.
D. Spreads: The ages of the koi are more spread out.
Im pretty sure he earned 495 in interest, because you take 5,500 time .03 (from the three percent) and you get 165- then multiply by three because of the three years (495)
