Dimas [21]

ANSWER

$- 7 \sqrt{6}$

EXPLANATION

The given radical expression is

$3 \sqrt{6} - 10 \sqrt{2} \times \sqrt{3}$

Recall and use

$\sqrt{a} \times \sqrt{b} = \sqrt{ab}$

to obtain;

$3 \sqrt{6} -10 \sqrt{2 \times 3}$

Simplify the second radicand.

$3 \sqrt{6} - 10 \sqrt{6}$

We have two like surds so we can simplify to obtain;

$- 7 \sqrt{6}$

F(x) = 2x^2 – 3x – 9<br> g(x) = 4x^2 - 9<br> Find ( f/g)(x).

Tomtit [17]

Answer:

(f/g)x = (x - 3)/(2x - 3)

Step-by-step explanation:

Try and see if f(x) can be factored.

g(x) = (2x - 3) (2x + 3)

That means that perhaps f(x) has one of these two factors.

(2x 3)(x 3)

You want the 2x and 3 to multiply. The middle term has to be -, so when 2x and 3 multiply likely it is 3 that gives you the minus answer.

(2x + 3)(x - 3) should be the way f(x) factors, and it is.

f(x) / g(x) =<u> (2x + 3) (x - 3)</u>

(2x + 3)(2x - 3)

2x + 3 cancels. The answer is

(f/g)x = (x - 3)/(2x - 3)

Plot a point on the coordinate plane to represent each of the ratio values in the table. Time (h) Distance (km) able displaying

Effectus [21]

Answer:

Refer the attached graph.

Step-by-step explanation:

Given : Time (h) Distance (km) able displaying Time in hours in one column and Distance in kilometers in the other. The time column contains 1, 3, 6, and 9. The distance column contains 2, 6, 12, and 18.

To plot : The points on the coordinate plane.

Solution :

Time is independent variable so it is taken on x-axis.

Distance is taken on y-axis.

x y

1 2

3 6

6 12

9 18

When we plot these points in the coordinate plane, we get a linear equation.

The linear equation form is $y=2x$

Refer the attached graph.
