If f(x)=2x^2-5 and g(x)=x^2-4x-8, find (f-g)(x)

Mathematics

Marianna [84]3 years ago

 (f-g)(x) is equivalent to f(x) - g(x)

So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3

Hope this helps.

3(m - 2) - 4>= 7m + 4
Use distributive property
3m - 6 - 4>= 7m + 4
Subtract 7m from both sides
-4m - 6 - 4>= 4
Add 6 to both sides
-4m - 4>= 10
Add 4 to both sides
-4m>= 14
Divide both sides by -4 so that the only thing remaining on the left side is the variable m.
Final Answer: m<= -14/4 or 3.5 or 3 1/2 *All the answers are equivalent to each other.

Which describes the slope of this line?
sergeinik [125]
I take the points that you gave. Let named A(0,-3) and B(2,1)

The slope coefficient is  S= (yb-ya)/(xb-xa)

S= (1-(-3))/(2-0) => S= (1+3)/2 = 4/2= +2 => S= +2

The correct answer is     positive slope
Good luck!!!

which equation is the equation of the line in point slope form that has a slope of 12 and passes through the point (-1,14)
Art [367]

y - 14 = 12( x + 1)

the equation of a line in ' point - slope form ' is

y - b = m(x - a) → (m is slope and (a, b) a point on the line)

here m = 12 and (a , b) = ( - 1, 14)

y - 14 = 12(x - (-1)) ⇒ y - 14 = 12( x + 1)
