Answer:

Slope of given line = $\frac{-9}{4}$ and slope of perpendicular line = $\frac{4}{9}$

Step-by-step explanation:

We are given a line -9x - 4y = 5 .

We have to find the slope of a line parallel to this line and also a line perpendicular to this line.

Let the general equation be ax + by = c.

Then the slope of this line = $\frac{-a}{b}$ = $\frac{-9}{4}$

The slope of a line perpendicular to a line is the negative inverse of the slope of the line. Using this concept,

Slope of line perpendicular to the given line = $\frac{b}{a}$ = $\frac{4}{9}$

What’s the area of this rectangle

attashe74 [19]

Answer:

$n^{2} +2n-15$

Step-by-step explanation:

Just multiply the two sides

1. $(n+5)(n-3)=A$

Use FOIL (First, Outer, Inner, Last)

2. $n^{2} +2n-15$

Pierce draws a circle with a radius of 3 centimeters. Ginna draws a circle with a radius that is twice as long as the radius of

erastova [34]

Answer:

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Step-by-step explanation:

Given:

Radius of the circle drawn by Pierce = 3 cm

We need to find circumference of gianna's circle compare with the circumference of Pierce's circle.

Solution:

Radius of the circle drawn by Pierce = 3 cm

so we will find the Circumference of circle drawn by Pierce.

Now we know that;

Circumference of the circle is given by 2 times π times radius of the circle.

framing in equation form we get;

Circumference of the circle drawn by Pierce = $2\pi\times 3=6\pi\ cm$

Now Given:

Ginna draws a circle with a radius that is twice as long as the radius of pierce's circle.

So we can say that;

radius of the circle drawn by Ginna is equal to 2 times radius of circle drawn.

so we can say that;

radius of the circle drawn by Ginna = $2\times3 = 6\ cm$

Circumference of the circle drawn by Ginna = $2\pi\times 6=12\pi\ cm$

Now we can see that;

Circumference of the circle drawn by Ginna is $12\pi \ cm$ while Circumference of the circle drawn by Pierce is $6\pi \ cm$

So we can say that;

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.
