Answer:
Slope = 3
Step-by-step explanation:
For a proportional relationship, the slope of the line is simply y/x.
So using any given pair of values from the table, say (1, 3), the slope is:
y/x = 3/1
Slope = 3
Answer:
graph the line then make a table
Step-by-step explanation:
Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
Answer:
A. The center of dilation is point C.
B. It is a reduction.
E. The scale factor is 2/5.
Step-by-step explanation:
The center is shown as C. You can see this from the line segments they drew through C, the image, and the pre-image.
The pre-image is the image before the dialation. The pre-image here is XYZ.
The image is the image after dialation. The image is X'Y'Z'.
If you look at the pre-image XYZ and then it's image X'Y'Z', ask yourself the image get smaller or larger. To me I see a larger triangle being reduce to a smaller triangle so this is a reduction.
The scale factor cannot be bigger than 1 because the image shrunk so D is definitely not a possibility.
E. is a possibility but let's actually find the scale factor to see.
We can calculate or or to find out what the scale factor is.
.
The scale factor is 2/5.
Answer:
A polynomial of degree 3 has 3 linear factors… (1): (x - i ) (x + i ) (x + a) . If any 2 factors are conjugate as here first 2 factors are conjugate with complex roots. So at least one root should be real.

Answer:
x ( b, c )
Step-by-step explanation:
x is the midpoint of PQ and its coordinates are the average of the coordinates of the endpoints P and Q , then
x = (, ) = ( b, c )
