Answer:The answer will be 2x
Step-by-step explanation:
B) The graph shifts 3 units down. i think is correct?
C) the graph shifts 3 units left.
D)the graph shifts 3 units right.
The statement that best describes the effect of replacing the graph of f(x) with the graph of f(x) - 3 is; B) The graph shifts 3 units down.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it. If we know that the function crosses x axis at some, then for some polynomial functions, we have those as roots of the polynomial.
The parent function is function of x and we the translated function is in the form f(x)-3.
Transformation Rule state that if the parent function is f(x) and if we subtract some constant 'a' in f(x) then the function will move down by 'a' units.
Thus, from the transformation rule, we can conclude that f(x) graph will shift down by 3 units.
Therefore, the correct option is; B) The graph shifts 3 units down.

Answer:
68 degrees
Step-by-step explanation:
The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.
The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft. Thus,
tan x = (opp side) / (adj side) = 10/4. Using the inverse tangent function, we find that the angle in question is
arctan (10/4) = 68 degrees
Scale shows weight = 193
Weight of assistant = 135
Weight of dog = x
x = 193 - 135
x = 58
The dog weighs 58 pounds.
