Answer:
the answer is -5 and 6
Step-by-step explanation:
Zeros of the function are -5 and 6.
<u>Step-by-step explanation: </u>
f(x) = x² - x - 30
Step 1:
Factorize the equation using Product and Sum method. Product = - 30 and Sum = - 1
⇒ f(x) = x² - 6x + 5x - 30
Step 2:
Solve the equation by equating the function to zero to find zeros.
⇒ x (x - 6) + 5(x - 6) = 0
⇒ (x - 6)(x + 5) = 0
⇒ x = 6, - 5

Answer:
B) 10 visits
Step-by-step explanation:
Let the number of visits be x.
Pool A cost: 1x + 40 = x + 40
Pool B cost: 5x
Set the two costs equal and solve for x.
x + 40 = 5x
Subtract 5x from both sides. Subtract 40 from both sides.
-4x = -40
Divide both sides by -4.
x = 10
