Simplify this expression

Sergeu [11.5K]

Answer:

option 4

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ = $\sqrt{ab}$

Given

(2 - 5 $\sqrt{6}$ ) 3 $\sqrt{2}$ ← distribute parenthesis by 3 $\sqrt{2}$

= 6 $\sqrt{2}$ - 15 $\sqrt{12}$

= 6 $\sqrt{2}$ - 15 $\sqrt{4(3)}$

= 6 $\sqrt{2}$ - 15( $\sqrt{4}$ × $\sqrt{3}$ )

= 6 $\sqrt{2}$ - 15(2 $\sqrt{3}$ )

= 6 $\sqrt{2}$ - 30 $\sqrt{3}$

HELP PLEASE!!! 25 Points & Brainliest!

Citrus2011 [14]

Answer:

(1) $f(x)=3x+4$

Ad g(x) represent f(x) after horizontal translation 2 units to the left.

$g(x)=3(x+2)+4$

$g(x)=3x+6+4$

$g(x)=3x+10$ is the required translation.

(2) $f(x)=\frac{-2x}{3}+2$

$f(\frac{1}{2})=\frac{-2}{3}\cdot(\frac{1}{2})+2$

$f(\frac{1}{2})=\frac{5}{3}$

(3) We have been given a point (1,-9); slope 2

We will use the equation:

$y-y_1=m(x-x_1)$

m is the give slope.

$y-(-9)=2(x-1)$

$y+9=2(x-1)$

Therefore, Option (a) is correct.
