Answer:
f(x) = x² + 7x + 12
Step-by-step explanation:
Given that the zeros are x = - 3 and x = - 4, then the factors are
(x - (- 3)) and (x - (- 4)), that is (x + 3) and (x + 4)
f(x) is the product of the factors, that is
f(x) = (x + 3)(x + 4) ← expand using FOIL
f(x) = x² + 7x + 12

Answer:
x=16, y=39
Step-by-step explanation:
to solve y=2x+7
Substitute 2x+7 for y in y=3x−9
y=3x−9
( solve this like a normal problem)
2x+7=3x−9 (Add -3x to both sides)
-x+7=-9 (Add -7 to both sides)
-x=-16 (Divide both sides by -1)
x=16
Now that you found x you can substitute this in the other problem.
y=3(16)-9
y=39

--- Midpoint of ST
Required
Determine the coordinates of S
To do this, we apply the mid-point formula:
Where
The equation becomes:
Multiply through by 2
By comparison:
Hence, the coordinates of S is:
