Answer:
y = - 
(x - 5)² + 7
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (5, 7 ) , then
y = a(x - 5)² + 7
To find a substitute (10, - 3 ) into the equation
- 3 = a(10 - 5)² + 7 ( subtract 7 from both sides )
- 10 = 5²a = 25a ( divide both sides by 25 )
= a , that is
a = -
y = - (x - 5)² + 7 ← in vertex form
Answer:
The opposite of - 5 would be 5
Step-by-step explanation:
Because opposite number only means a number with an oposite sign
Answer: A
Step-by-step explanation: A function means that your x can only have one y but your y can have multiple x's.
Answer:
Manager will get $40
Step-by-step explanation:
2400*(1/12)=200, so Dylan made $200
200*(1/5)=40, so the manager made $40
