Answer:
(3, - 25 )
Step-by-step explanation:
Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0
The the x- coordinate of the turning point is
x = -
Given
y = (x + 2)(x - 8) ← expand factors using FOIL
= x² - 6x - 16 ← in standard form
with a = 1 and b = - 6, thus
x = - = 3
Substitute x = 3 into the equation for corresponding value of y
y = (3 + 2)(3 - 8) = 5(- 5) = - 25
turning point at (3, - 25 )
Answer:
Red color= 28 balloon
Blue color= 14 balloon
White color= 7 balloon
Step-by-step explanation:
Given: There are 49 balloons
As given, there are 2 red balloon equal to the number of blue balloon
∴
Again given, there are 1/2 white balloon equal to the number of blue balloon.
∴
As above equation, we can understand that:
multiplying both side by 2
⇒
which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.
∴ Total combination of all color of balloon=
Now, checking how many number of times combination can we have in 49 balloon.
Next, finding number of balloon in each color.
Red color=
Blues color=
White color=
