Answer:
26%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
Here, the new number is £504, and the old number is £400.
percent change = (£504 - £400)/(£400) * 100% =
= £104/£400 * 100% = 0.26 * 100% = 26%
ANSWER

EXPLANATION
The line given to us has equation,

We need to write this equation in the slope intercept form to obtain,


The slope of this line is

Let the slope of the perpendicular line be

Then


This implies that,


Let the equation of the perpendicular line be,

We substitute the slope to get,

Since this line passes through

it must satisfy its equation.
This means that,




Wherefore the slope-intercept form is
Welp someone already answered and I just gotta answer questions so goodluck :)

Answer:
Distance of the point from its image = 8.56 units
Step-by-step explanation:
Given,
Co-ordinates of point is (-2, 3,-4)
Let's say



Distance is measure across the line

So, we can write




Since, the equation of plane is given by
x+y+z=3
The point which intersect the point will satisfy the equation of plane.
So, we can write




So,









Now, the distance of point from the plane is given by,






So, the distance of the point from its image can be given by,
D = 2d = 2 x 4.28
= 8.56 unit
So, the distance of a point from it's image is 8.56 units.
