Show your work and write an expression using the following criteria:
1. divide 4,200 by a multiple of 10
2. the quotient is also a multiple of 10

The required number which is a multiple of 10 is 20.

Step-by-step explanation:

1. We have to divide 4200 by a number which is a multiple of 10.

Let us assume that the number is 20, which is a multiple of 10.

Now, after division the quotient will be .

2. We have to check whether the quotient is multiple of 10 or not.

Here, the quotient is 210 which is a multiple of 10.

Hence, the required number which is a multiple of 10 is 20. (Answer)

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

is only a line? i think so
