Answer:

16 direct

17 indirect

Step-by-step explanation:

16.

If it is a direct variation

y/x = constant

4/-2 -2

-8/4 = -2

-12/6 = -2

This is a direct variation

17.

y/x = -1/2 /-2 = 1/4

y/x = -1/-1 = 1

This is not a direct variation

If it is an indirect variation then

yx = constant

-1/2 * -2 = 1

-1*-1 =1

3 * 1/3 =1

This is an indirect variation

Each of the linear factors occurs precisely once, so the sign of the given rational expression will change at each of the points where one of the linear factors is zero. That is at:

−

Note that when

When

−

, the denominator is zero so the rational expression is undefined. Since the numerator is non-zero at those values, the function will have vertical asymptotes at those points (and not satisfy the inequality).

When

, the numerator is zero and the denominator is non-zero. So the function will be zero and satisfy the inequality at those points.

Hence the solution is:

What value should be added to the expression to create a perfect square?

Shalnov [3]

Let's take a look at a perfect square trinomial.

$(x+7)^2$

We can distribute this expression to get $x^2+14x+49$ .

An important relation to recognize here is that the constant is the square of half of the x value.

Now, if we wanted to add a number to $x^2+16x$ to make a perfect square trinomial, we could have the value of x and then square it.

Half of 16 is 8, and 8 squared is $\boxed{64}$

Jacob borrowed $30, 000 to start up his consulting business. The loan had simple interest rate of 6.2% for 3 years. Use I= part

sammy [17]

Answer:

The amount of interest is $5580.

Step-by-step explanation:

Given : Jacob borrowed $30, 000 to start up his consulting business. The loan had simple interest rate of 6.2% for 3 years.

To find : The amount of interest he will pay with the loan ?

Solution :

Using interest formula,

$I=P\times R\times T$

Where, P is the principal P=$30,000

R is the rate of interest R=6.2%=0.062

T is the time t=3 years.

Substitute the value in the formula,

$I=30000\times 0.062\times 3$

$I=5580$

Therefore, The amount of interest is $5580.
