Answer:

Step-by-step explanation:
Let
x -----> Kevin’s savings accounts amount at the beginning of the month
Remember that

we know that
The amount in Kevin’s account at the end of the month is equal at the amount at the beginning of the month multiplied by 1.04
so

Answer:
210 km
Step-by-step explanation:
90 * 2 is 180 (distance over 2 hours)
20 minutes is .333 hours, so 90*0.333 is about 30 km
and 180+30 is 210.
Answer:
8y-2
Step-by-step explanation:
I multiplied the dimensions and divided it by 75, got 8.75 but you need to round in this situation, so 9
hope this helps :)
Answer: The first option is correct.
Explanation:
The given piecewise function is,

From the piecewise function we can say that if x<0, then

If
, then

Since the f(x) is defined for x<0 and
, therefore the function f(x) is not defined for
.
In the graph 2, 3 and 4 for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.
Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for
, hence the first option is correct.
