Answer:
36
Step-by-step explanation:
Hello,
If it becomes
and
So,
a = 1
b = 1
c = 17
d = 17
e = 0
Then a + b + c + d + e = 36
Thanks
Answer:
z=-8
Step-by-step explanation:
38=2z+54
then subtract 54 from each side
-16=2z
then divide by 2
and you get z=-8

Answer:
he would have to be at the mountain by 7:45
Step-by-step explanation:
if I'm not mistaken it would take him six hours in total to be up and down the mountain and 7:45 - 1:45 = 6
The coordinates of the vertex of the graph are (-2, -9).
<h3>Further explanation</h3>
The quadratic function is described by the standard equation The graph of a quadratic function is called a parabola.
We have the quadratic function
- We identify the coefficients a, b, and c. For this equation,
- The axis of symmetry is , i.e., Thus, the statement in the question for the symmetry axis x = -2 is correct.
- The vertex (or turning point) is where or
- The parabola opens upward because a > 0, resulting in a vertex that is a minimum.
Finding the minimum value is as follows:
Therefore, the coordinates of the vertex of the graph are (h, k), i.e.,
Other components:
- The y-intercept of the quadratic function f(x) = x² + 4x - 5 is (0, c), i.e., the point
- The factorization of f (x) = x² + 4x - 5 becomes f(x) = (x + 5)(x - 1). Then we get the x-intercepts at
