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

Answers

Answer:

(5, 0 )

Step-by-step explanation:

Given the 2 equations

y = x² - 2x - 15 → (1)

y = 8x - 40 → (2)

Substitute y = x² - 2x - 15 into (2)

x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )

x² - 10x + 25 = 0 ← in standard form

(x - 5)² = 0 ← in factored form, thus

x - 5 = 0 ⇒ x = 5

Substitute x = 5 into (2) for corresponding value of y

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

Solution is (5, 0 )

Answer: b

(5,0)

Step-by-step explanation:

24x + 34p = p
Solve for p

Answers

Answer:

(-24)/(33) x = p

Step-by-step explanation:

24x + 34p = p  Subtract 34 p from both sides of the equation

24x + 34p -34p = p - 34p

24x = -33p  Divide both sides by -33

(24x)/(-33) = (-33p)/(-33)

(24x)/(-33) = p or .2727...
