Answer:
Marc's age is 12
Step-by-step explanation:
Let
x ----> Marc's age
y ---> Tony's age
z ---> Ben's age
we know that
the sum of their ages is 40
so
-----> equation A
Marc is half as old as Tony
so
----> equation B
Marc is three times as old as Ben
so
----> equation C
substitute equation B and equation C in equation A
solve for x
therefore
Marc's age is 12
Answer:
We are given the function, f(x) = |2x+4| + 1.
Now, as we can see that this function is obtained after applying following transformation to the function g(x) = |x|.
1. Dilation i.e. shrinking the graph horizontally by 2 units
2. Translation i.e. shifting the figure in 4 units to the left and 1 unit up.
Hence, after plotting the function f(x) = |2x+4| + 1, we get the following graph.
