Are you kidding me? It's 21.2 because there is only one decimal place
Given:
The graph of two lines.
To find:
The slope of each line and check whether they are same or different.
Solution:
If a line passes through two points, then the slope of a line is:

From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:



The slope of first line is 10.
From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:



The slope of second line is 10.

Therefore, the slopes of both lines are same, i.e. 10.
Umm isn’t it 36 I don’t know
Do u mean what is f(8)?
(X) = 2x + 5
Inverse = (x-5)/2
F(x) = (x-5)/2
F(8) = (8-5)/2
= 3/2 = 1.5
Answer:
∠PST = 45°
Step-by-step explanation:
The diagonals of a square bisect the angles
∠SPQ = 90° ⇒ ∠SPT = 45°
