Look at your picture
notice the coordinates for the center of the circle, the x,y or h,k values
notice how long the radius is
thus
Answer:
f(x) = x^2 -2x -8
Step-by-step explanation:
(x+2)(x-4)
FOIL
first: x*x = x^2
outer: -4x
inner: 2x
last: 2*-4x = -8
Add together
x^2 +2x-4x-8
x^2 -2x -8
This is a parabola
Answer:
The slope of the line is 7/2.
Step-by-step explanation:
If a line passes through two points
and
, then the slope of the line is

From the given figure it is clear that the line passes though two points (0,0) and (4,14).
Using the above formula, the slope of the line is



Therefore the slope of the line is 7/2.
The factor that multiplies with 6 to get 18 is 3 but the factor that multiplies with 6 to get 30 is 5.
The numbers in parenthesis should be a 5 and not a 10.
18 + 30 = 6(3 + 5)
