Answer:

Option D: 5√5 is the correct answer.

Step-by-step explanation:

Given that:

√20 + √45

These can also be written in simplified form;

√5*4 + √5*9

We will take square root of 4 and 9.

The square root of 4 and 9 is,

√4 = 2

√9 = 3

Thus,

2√5 + 3√5

Adding the roots,

5√5

Hence,

Option D: 5√5 is the correct answer.

Find the equation in standard form , of the line passing through points (2,-3) and (4,2)

Fudgin [204]

The form of linear equation that describes line is:

$y=sx+n$

First we must calculate the slope.

$s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}$

Now it looks a bit more like this:

$y=\dfrac{5}{2}x+n$

All we need now is to put in y and x from one point doesn't matter which. I'll pick A.

The equation now looks like this:

$-3=\dfrac{5}{2}\cdot2+n$

Solve for n.

$-3=5+n \\n=-8$

And finally write the equation.

$f(x)=\dfrac{5}{2}x-8$

Hope this helps.
