Answer:
y= -2x+9
Step-by-step explanation:
The equation will be written this way :
y= m*x+c
- m is the slope
- c is a constant
- m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
- y = -2x+c
- replace x and y by the coordinates of a point to get c
- 1= -2*4+c
- c = 9
y = -2x+9
Answer:
(x+3)( 5x-3)
Step-by-step explanation:
f(x) = 5x² + 12x – 9
Factor
(x+3)( 5x-3)
You would set your equation up as basically f(x)-g(x), so:
(3x-4)-(x+2)
combine your like terms and you should have your answer:
2x-6
