Answer:
Graph A.
Step-by-step explanation:
When x is equal to 0, why has to be equal to 2. The slope also has to be 3. To find this out, we do y2-y1/x2-x1. For A, the slope is -7--4/-3--2. This is equal to -3/-1. This is equal to 3. Because y=2 when x=0. option A is correct. For option D, when x=0, y=32. Therefore, this option is not correct. For option B, when x=0, y=2 so this could be correct. Plug it into y2-y1/x2-x1. This is equal to -1-0/-1-2. This is equal to -1/-3. 1/3 is not equal 3 so this option is not correct either. When x=0, y=32 for option C. Therefore, this option is not correct. Therefore, the answer is option A.

Answer:
18. 28 cm*2
19. 24 m
Step-by-step explanation:
18. length × l = 16
l*2= 16
l = 4
RQ = 4 cm
PR =7cm
Area of parallelogram = b×h
= 7×4
=28cm*2
19. 8 +8 + (6-2) +( 6- 2)
=24 m
Answer:
<u>Not true</u>: B. The radicand has been multiplied by -1.
Step-by-step explanation:
The parent function of √x has been vertically reflected and translated, but has not been horizontally reflected. Hence the sign of x is positive, not multiplied by -1.
_____
In the attached graph, the parent function (A. y=√x) is shown in purple. The function with the radicand made negative is shown in red (as a dashed line). Clearly this does not match the graph provided with your problem.
The function shown in green has the transformations described by answers C and D.
The common difference is essentially what u need to add to one number in the sequence to get the next
So previous number + common difference = next number after that
The common difference would be -8
Rotation by 180° negates both coordinates.
.. B = (4, -11) . . . . . . . corresponding to the 1st selection
