7(2q-5) {{q=3}}
= 7(2x3-5)
= 7(6-5)
= 7(1)
= 7
The answer is 7.
Answer:
The model on the top right.
Answer: 1
Explanation: Doing -50+51 is essentially the same as 51-50
Is this for calculus for for algebra?
I'm going to assume that you know calculus.
df
---- = 2ax + b must equal zero if (-1,2) is an extreme value of f(x).
dx
Thus, 2ax + b = 0, and 2ax = -b, or x = -b/(2a). This is the familiar "x-coordinate of the vertex of a parabola."
Here that x-value is -1, so -1 = -b/(2a). From this we get -2a = -b, or
b=2a
so the ordered pair could be (a, 2a).
