Which represents the solution(s) of the system of equations, y = x2 – 2x – 15 and y = 8x – 40? determine the solution set algebraically.

(–5, –80)
(5, 0)
(5, 0) and (–5, –80)
no solutions

Option B is correct

(5, 0)

Step-by-step explanation:

Given the system of equation:

     ....[1]

           ....[2]

Equate equation [1] and [2] we have;

Subtract 8x from both sides we have;

Add 40 both sides we have;

we can write this as:

Using the identity rule:

then;

⇒x-5 = 0

⇒x = 5

Substitute in [2] we have;

y = 8(5)-40 = 40-40 = 0

⇒y = 0

Solution = (5, 0)

Therefore, the solution(s) of the system of equations is, (5, 0)

the correct answer is a.) bc< mn 5 stars if this you : )
