Answer:
10
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.
To solve for x, cross multiply:
12(x+4) = (2x+1)(8)
12x + 48 = 16x + 8
48 = 4x + 8
40 = 4x
10 = x
Answer:
The domain is all real values
Step-by-step explanation:
The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
In this case, we can observe from the graph that the function is defined for all x-values. So the domain is all real values.
