Answer:
ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.
Step-by-step explanation:
It is given that the triangle ABC is dilated to produce triangle A'B'C' with scale factor 3/4.
If a figure is dilated then preimage and image are similar.
If scale factor is between 0 to 1, then preimage is reduction of image.
If scale factor is more that 1, then preimage is enlargement of image.
If scale factor is 1, then preimage is congruent to the image.
We know that
So,
Therefore, the ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.
Answer:
A. F(x)is an even function so both ends of the graph go in the same direction.
D. The leading coefficient is negative so the left end of the graph goes down.
Step-by-step explanation:
Even function:
For every value of x, f(x) = f(-x)
In this question:
We are given the following function:
Testing if it is even:
Since f(1) = f(-1), it is even.
Since it is even, both ends of the graph go in the same direction, so option A is correct, while option B is wrong.
Options C and D:
The leading coefficient, is -4(which multiplies x with the highest exponent). Since it is negative, it goes to negative infinity as x increases, that is, the left end goes down, and option D is correct while C is not.

Answer:
no solution
Step-by-step explanation:
Adding the two equations gives you ...
(-7x -4y) +(7x +4y) = (11) +(20)
0 = 31 . . . . . . false
No values of the variables will make this equation true. There is no solution.
For the table
10 —> 4
1 —> 0.4
20 —> 8
40 —> 16
39 —> 15.6
Answer:
x>-4
Step-by-step explanation:
-8x<32 - First isolate the x by dividing both sides by -8
-8x/-8<32/-8
x>-4
