Answer:
1
Step-by-step explanation:
Firstly note that the graph is shifted up 2 units, as it starts at positive 2, when it should start at 0.
That only leaves choices 1 and 2
However, since we know its flipped, we can easily rule out number 2, as number 2 wouldn't be a real number(sqrt of negatives)
That leaves answer choice 1
Answer:
vertex = (- 2, - 36)
Step-by-step explanation:
Given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = 5x² + 20x - 16 is in standard form
with a = 5, b = 20 and c = - 16
= - 
= - 2
Substitute x = - 2 into f(x) for corresponding y- coordinate
f(- 2) = 5(- 2)² +20(- 2) - 16 = 20 - 40 - 16 = - 36
vertex = (- 2, - 36)
Answer:
William weighs 111 pounds.
Step-by-step explanation:
N = x+6
W = x
T = x-3
x+6+x+x-3=336
3x + 3 = 336
3x = 336 - 3
x = 333/3
x = 111
First ask yourselfhat needs to be dristributed.
That would be -1 (x-9)
To distribute you have to multiply the number out side of the parentheses (-1) by each term inside the parentheses( x and -9)
-1×x=-x
-1×-9=9
Now the expression is
-x+9+4x
To simplify you have to combine like terms (4x and-x)
4x-x=3x
Your answer is 9+3x or 3(3+x).
