Answer:
money : x
in 2 years : x+2
in 5years: x+2= 2800 + 3250
sum= x+2= 6050
x=6050÷2
x=3025
Option B: 5 is the value of f(3)
Explanation:
The equation of the piecewise function is given by

We need to find the value of 
The value of the function f can be determined when
by identifying in which interval does the value of
lie in the piecewise function.
Thus,
lies in the interval
, the function f is given by

Substituting
in the function
, we get,


Thus, the value of
is 5.
Therefore, Option B is the correct answer.
Answer:
y = -2/13
Step-by-step explanation:
-5 + 13y = -7
Add 5 to each side
-5+5 + 13y = -7+5
13y = -2
Divide by 13
13y/13 = -2/13
y = -2/13
Answer: 24.6 inches
Step-by-step explanation: Since it's a rectangle, and not a rectangular prism, that means it's 2D. Length is the long sides on the top and bottom, and width is the shorter sides on it's left and right. So since there's two of each, just do 8.1 + 8.1 + 4.2 + 4.2 and you have your answer!
