Answer: f(x)=mx+b
f(x)=x+7
if x=2 then
f(2)=2+7=9
A function is linear if it can be defined by
f(x)=mx+b
f(x) is the value of the function.
m is the slope of the line.
b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
x is the value of the x-coordinate.
Answer:
1
Step-by-step explanation:
Cosine = adjacent/hypotenuse
Cos A = 3/4.24
Cos B = 3/4.24
Since they are equivalent, Cos A/Cos B = 1
Answer:
37.5 sq. units.
Step-by-step explanation:
The coordinate of vertices of trapezoid ABCD are given,
From the diagram it is clear the area of ABCD = 
{Since, AD ║ BC and AB is the perpendicular distance between the parallel lines }
Now, AB = 
units
AD = 
units
Again, BC = 
units
Therefore, the area of trapezoid ABCD = 
sq. units. (Answer)
We know, that the distance formula between two points 
and 
is
.
