Answer:
x=6
Step-by-step explanation:
Given the x-intercepts of a parabola: 
The equation of symmetry at the parabola's vertex is x=h
Where 
In this case,
Therefore, the line of symmetry of the parabola is x=6 and is also the x-coordinate of the parabola's vertex.
Answer: 6,000
If the value before the one you are rounding to is 5 or greater then round up. If it is 4 or less round down.
Answer:
Step-by-step explanation:
I'm not sure I know exactly what that [1] means.
But here's how you get the answer
g(x) = 3x + 12
The symbolism means that wherever you see an x on the right side of g(x) you put f(x)
So it looks like this
g(f(x) ) = 3(f(x)) + 12 Now you put f(x) = 2x + 7 in for f(x) on the right.
g(f(x)) = 3(2x + 7) + 12 Remove the brackets
g(f(x)) = 6x + 21 + 12
g(f(x)) = 6x + 33
Now you deal with the x on the left. It becomes - 6
g(f(-6)) = 6(-6) + 33
g(f(-6)) = -36 + 33
g(f(-6)) = - 3
Rule 1
(g · f)(x)
has the meaning of whatever the function on the left is (in this case g) then the function of f is put in the xs place.
Answer:
68
Step-by-step explanation:
68 numbers from 1 to less than 69
Answer:
42
Step-by-step explanation:
x+(x+13)=71
2x+13=71
2x=71-13
2x=58
x=29 (alvin)
71-29=42 (elga)
