Answer:

C.)

Step-by-step explanation:

There are multiple technical ways to explain this but the best one that works for me is the "vertical line test" can be used to find a function or non function. All you have to do is position your pencil vertically, place it to the far left of the graph drag it horizontally across to the right side of the graph. If your pencil is making contact with two lines at one time, it is NOT a function. Hopefully this makes sense.

Divide.

Answer:

Answer in simplified form is - 10 1/2 .

Step-by-step explanation:

We have given,

(5 1/4) ÷ (- 2 1/2)

This can be simplified as :

(5 1/4) ÷ ( -2 1/2)

Since 5 1/4 = 21/4 and -2 1/ 2 = -5/2

So we can write,

(5 1/4) ÷ ( -2 1/2) = 21/4 ÷ ( - 5/2)

or (21/4) / (-5/2)

or ( 21/4) * (-2/5)

or -42/20

or -21/10

or - 10 1/2 , this is the answer

Hence we get answer in simplified form as -10 1/2

What does 4 5/8 - 1 2/5 equal?

mihalych1998 [28]

$4 \frac{5}{8} - 1 \frac{2}{5} \\ \\ \frac{37}{8} - \frac{7}{5} \\ \\ \frac{185}{40} - \frac{56}{40} = \frac{185 - 56}{40} \\ \\ = \frac{129}{40} = 3.225 = 3 \frac{9}{40}$

Mark borrowed $600 at an intrest rate of 8% per year for 4 years. How much simple intrest will he have to pay?

miv72 [106K]

Answer:

He will have to pay $192 in simple interest.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the interest, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this problem, we have that:

P = 600, r = 0.08, t = 4

E = P*I*t = 600*0.08*4 = 192

He will have to pay $192 in simple interest.
