First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
Answer: 10x5x4= 200 meters^3
y=x-3 is the most plausible answer i can give you. Was that the whole question?
Answer:
Hence, the graph is decreasing in the interval: –4 ≤ x ≤ 2 ( option: B is correct)
Step-by-step explanation:
We have to define the interval in which the graph of the given function is decreasing.
Clearly by looking at the graph we could see that the graph is first increasing till x<-4.
and then it decreases in the interval [-4,2] since the value of y changes from y=9 at x= -4 to y= -9 at x=2.
also after x=2 the graph increases till x=6 and after x=6 the graph is constant i.e. the graph is represented by the line:
y=5 in the interval x≥6.
Hence, the graph is decreasing in the interval:
–4 ≤ x ≤ 2 ( option: B is correct)
