Answer:

A. $y=-\dfrac{8}{7}x-\dfrac{18}{7}$

Step-by-step explanation:

Let $y=mx+b$ be the equation of the perpendicular line.

Two perpendicular lines have slopes with product equal to -1. The slope of the given line is $\frac{7}{8}$ Hence,

$\dfrac{7}{8}\cdot m=-1\\ \\m=-\dfrac{8}{7}$

is the slope of needed line.

This line passes through the point (-4,2), so its coordinates satisfy the equation:

$2=-\dfrac{8}{7}\cdot (-4)+b\\ \\b=2-\dfrac{32}{7}=-\dfrac{18}{7}$

Therefore, the equation of the line is

$y=-\dfrac{8}{7}x-\dfrac{18}{7}$

Vinil7 [7]

Okay so instead of dividing you will cross multiply.
4n(15)=84(5)
60n=420
420/60=7

Answer:

-85

Explanation:

Given the mathematical expression:

$-18+(-67)$

First, we recall the product of signs.

$+\times-=-$

So, first, we open the bracket:

$-18+(-67)=-18-67$

We then simplify:

$=-85$

The result is -85.
