Answer:
(a) y = -3/4x +36
Step-by-step explanation:
The slope of the rail is ...
m = rise/run = -9/12 = -3/4
The initial height of the rail is 36, so the slope-intercept equation for the rail is ...
y = mx +b . . . . . m = slope; b = initial value
y = -3/4x + 36
Answer:
Step-by-step explanation:
<u>The scale factor is the ratio of corresponding side of the image to te original:</u>
- k = A'C'/AC
- k = 6/24 = 1/4
Mean (the average):
is the mean
Median (the middle number when the numbers are ordered):
87
Mode (most repeated number(s)):
74 and 87
Range (difference between the highest and the lowest values):
115-67=48
Since BE bisects angle ABC, you know that angles ABE and EBC are congruent and have the same measure. This means
2x + 20 = 4x - 6
Solve for x:
(2x + 20) - 2x + 6 = (4x - 6) - 2x + 6
26 = 2x
26/2 = 2x/2
13 = x
Then angle ABE has measure 2*13 + 20 = 46º.
