Answer:

- 4 $\sqrt{2}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplify $\sqrt{18}$ using this rule

$\sqrt{18}$

= $\sqrt{9(2)}$

= $\sqrt{9}$ × $\sqrt{2}$ = 3 $\sqrt{2}$

Then

- 2 $\sqrt{18}$ + 2 $\sqrt{2}$

= - 2(3 $\sqrt{2}$ ) + 2 $\sqrt{2}$

= - 6 $\sqrt{2}$ + 2 $\sqrt{2}$

= - 4 $\sqrt{2}$

Need help on this question writing linear equations

Mrrafil [7]

if you look at delta y over x, you'll notice it always equals 2

i.e (22-2)/10-0 = 20/10 = 2

or (14-2)/6-0 = 12/6 = 2

or even (22-8)/10-3 = 14/7 = 2

This means that m (slope) is 2.

Now as for b. b is the y intercept and that value occurs when x = 0. On the table, when x = 0 y = 2 so b = 2.

y = mx + b becomes

y = 2x + 2
