Answer:

$- 9 \sqrt{48} - 8 \sqrt{12} \\ = - 9 \times 4 \sqrt{3} - 8 \times 2 \sqrt{3} \\ = - 36 \sqrt{3} - 16 \sqrt{3} \\ = \sqrt{3} ( - 36 - 16) \\ = \sqrt{3} \times - 52 \\ = - 52 \sqrt{3} \\ thank \: you$

Match the reasons with the statements in the proof.

Len [333]

Observe the given figure.

Given: $m \angle 1 = m \angle 3, m \angle 2 = m \angle 3$

To prove: $l \parallel m$

Statement

1. $m \angle 1 = m \angle 3, m \angle 2 = m \angle 3$

Reason: Given

2. $m \angle 1 = m \angle 2$

Reason: Substitution

3. $\angle 1,\angle 2$ are alternate interior angles.

Reason: Definition of alternate interior angles

4. $l \parallel m$

Reason: If alternate interior angles are equal, then the lines are parallel.

Fill in the missing numbers to the linear eqution

V125BC [204]

Answer:

$y=-30x+0$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem the linear equation represent a proportional relationship, because pass through the origin (0,0).

Find the value of the constant of proportionality k

For x=1, y=-30

substitute

$k=\frac{-30}{1}=-30$

the linear equation is

$y=-30x$

therefore

$y=-30x+0$
