Answer:
C. (-5,0) and (3,0)
Step-by-step explanation:
y= x² + 2x-15
y = 0
x² + 2x-15 = 0
(x - 3) (x + 5) = 0
x = 3 or x = -5
Method is not mentioned , so
3x - 2y = 12 -----: ( 1 )
6x - 4y = 24 -----: ( 2 )
Now,
= > 24 = 24
= > 2( 12 ) = 24
= > 2( 3x - 2 y ) = 6x - 4y
= > 6x - 4y = 6x - 4y
RHS = LHS
Hence, the equation has infinitely many solutions.

Answer:
Step-by-step explanation:
1. asks you to add the two functions and , which would be
Simplify the like-terms and you get:
------------------
2. asks you to multiply the two functions and , which would be
In order to multiply the functions we use the FOIL method (for polynomials):
Multiply each term and you get:
Simplify the like-terms and you get:
------------------
3. asks for your ability to understand what composite functions are. In order to solve this, we will follow some careful steps and solve them separately.
