Answer:
48 ft.
Step-by-step explanation:
Since triangles ABC and DEC are similar (you can prove this quite easily), then we know the ratio of the sides are equal. This is a property of similar triangles. So we take the ratio of the sides CE and DE and the ratios of the sidesBC and AB.
We get:
So x is 48 ft.

The graph of function f(x) and g(x) is parallel lines separated by 1 unit.
In this question we have been given two functions f(x) = - 3x + 4 and g(x) = f(x) + 1
We need to graph these functions and then describe the graph.
The graph of given functions is as shown below.
The graph of function f(x) is a straight line with slope -3 and y-intercept 4.
The function g(x) is nothing but but function f(x) translated upward by 1 unit.
The graph of function g(x) is also a straight line with slope -3 and y-intercept 5.
Therefore, the graph of function f(x) and g(x) is parallel lines separated by 1 unit.

Answer:
D
Step-by-step explanation:
The x-values are evenly-spaced, so any linear function table will have constant differences between the y-values. Here are the y-differences for the different options:
A 1, 2, 4
B 1, -1, 3
C -1, -2, 1
D 5, 5, 5 . . . . this represents a linear function
