Answer:
ax² + bx + c
Step-by-step explanation:
The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.
Suppose a quadratic function:
f(x) = 2x² - 8x + 9
Use ( -b/2a , f(-b/2a) ).
-b/2a
a = 2
b = -8
-(-8)/2(2)
8/4
= 2
f(2) = 2(2)² - 8(2) + 9
f(2) = 2(4) - 8(2) + 9
f(2) = 8 - 16 + 9
f(2) = 1
The minimum value of this quadratic function is (2, 1).
It represents a minimum value because a > 0.
I think it’s 305 because there are 360 degrees about a point so 55 clockwise would be 305 anti-clockwise
Answer: can u explain it more plz
Step-by-step explanation:
Answer:
(5,10)
Step-by-step explanation:
So we have the system of equations:
To solve, we can use substitution.
Substitute the first equation into the second:
Combine like terms:
Subtract 5:
Divide by 4:
Now, substitute this into the first equation:
Add:
So, our answer is (5,10)
And we are done :)
