Answer:
To find how much money they shared first find the total parts
Which is
5 + 7 + 8 = 20
Deila's share is
5 /20 × £1600
= 1/4 × £1600 = £ 400
Edwin's share is
7/ 20 ×£1600 = £560
Freya's share is
8/20 × £1600
= 2/5 × £1600 = £640
Hope this helps you
Here is how the graph would look!

Since 25% is 1/4, then 180 times 4 is 720.
720 is your answer.
The slope of the perpendicular line of y=5x would be -1/5, since slopes are always opposite reciprocals when they are perpendicular to each other.
Answer:
4
Step-by-step explanation:
Slope refers to the steepness of the line.
Slope is equal to change in value of y divided by change in value of x.
The slope of the secant line is given by
.
Given points are 
So, slope of the secant line is 
(i) At x = 4.9,

(ii) At x = 4.99,

(iii) At x = 4.999,

(iv) At x = 4.9999,

(v) At x =5.1,

(vi)
At x = 5.01,

(vii) At x = 5.001,

(viii) At x = 5.0001,

(b)
Slope of the tangent line is 4.
