Answer:
<h3>13.8</h3>
Step-by-step explanation:
if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;
XY/YZ = 1/4
cross multiply;
YZ = 4XY
Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3
XY = 2.5
YZ = 4(2.5)
YZ = 10
Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y
coordinate of Z = 10+3.8
coordinate of Z = 13.8
Answer:
C) Horizontal compression
Step-by-step explanation:
Since, if y = f(x) is a function,
Then y = a f(x) gives a vertical stretch if a > 1 and gives a vertical compression if 0 < a < 1.
Also, y = f(bx) gives a horizontal stretch when 0 < b < 1 and gives a horizontal compression if b > 1.
Here,
The given parent function is,
f(x) = 2x
And, 3 > 1
Thus, by the above statements,
f(3x) will give a horizontal compression.
Hence, Option C is correct.
