-5(1 - 5x) + 5(-8x - 2) = -4x - 8x
-5 + 25x - 40x - 10 = -4x - 8x
-15 - 15x = -12x
-3x = 15
x = -5
Answer:
(B) The raw data can be retrieved from the dot plot, but not the histogram.
(C) Dot plots show the frequency of individual data values.
Step-by-step explanation:
There are two correct answers:
(B) The raw data can be retrieved from the dot plot, but not the histogram.
(C) Dot plots show the frequency of individual data values.
Dot plots are used for small data sets where values fall into a number of categories, unlike histograms.
Answer:
x = 1
Step-by-step explanation:
The line 1 passing through the points (-2,4), (0,2) and (1,1) is represented by the function f(x).
Again the line 2 is represented by y = g(x) and it passes through the points (-3,-3), (0,0) and (1,1).
So the only common point between line 1 and line 2 is (1,1) and it will be unique since two straight lines meet at only one point if they are not parallel.
Hence, for x = 1 input value produces the same output value y = 1 for the two functions f(x) and g(x) on the graph. (Answer)

Answer:
Step-by-step explanation:
The slope formula is useful for this.
m = (y2 -y1)/(x2 -x1)
__
<u>First line</u>:
m = (-9 -(-9))/(9 -(-6)) = 0/15 = 0
The slope of the first line is zero.
__
<u>Second line</u>:
m = (-5-1)/(4 -4) = -6/0 = undefined
The slope of the second line is undefined.
_____
It is always a good idea to apply a little critical thinking to the given information. Here, you observe that the y-coordinates of the first pair of points are the same. That means this is a horizontal line, with a slope of 0.
Similarly, you observe that the x-coordinates of the second pair of points are the same. That means this is a vertical line, with undefined slope.
