Answer:
Step-by-step explanation:
y = 
Find two points
When x = 0 , y = 0 + 2 = 2
D(0 , 2)
When x = 5;

E(5, 3)
Plot (0, 2 ) and (5 , 3) in the graph and join the points. This will be the line for the equation y =(1/5)x + 2
y = -x + 8
When x =4 , y = -4 + 8 = 4
A(4 , 4)
When x = 6 ; y = -6 + 8 = 2
B(6 , 2)
Plot (4,4) and (6, 2) in the graph and join the points. This will be the line for the equation y = - x + 8.
This lines will intersect at point (5,3) and that point will be the solution of the equation.
Answer: The correct option is tan(F).
Explanation:
In the given figure the triangle is a right angle triangle because
.
It is also given that
and
.
Since it is an isosceles right angle triangle, therefore the value of perpendicular and base is same for both angles D and F, which is 5.

The value of cos(F) is
.

The value of sin(F) is
.

The value of sin(D) is
.

The value of tan(F) is 1. Which is not equal to
.

The value of cos(D) is
.
Therefore, the value of tan(F) is not equal to the value of cos(F), so the correct option is third.

This is the longer leg of this triangle
Just from the figure,
As x decreases, y approaches 0
As x increases, y increases without bound
B. might be 4/x=3/4. I'm no mathematician, but if it's wrong, blame my teacher. d would probably be something. I'm no good with numbers.
