Answer:
Total cost = $111
Step-by-step explanation:
Given:
Total number of oak tree = 3
Total number of elm tree = 1
Each oak tree cost = $23
Each elm tree cost = $42
Find:
Total cost
Computation:
Total cost = 3[Each oak tree cost] + 1[Each elm tree cost]
Total cost = 3[23] + 1[42]
Total cost = 69 + 42
Total cost = $111
The answer your looking for is 3x - 6
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is 
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: 
y = 4x^2 + 8x + 3: 
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
Answer:
11/18
Step-by-step explanation:
The desired probability is the sum of ...
... (probability of choosing a coin) × (p(heads) on that coin)
Since the coins are chosen at random, we assume the probability of choosing a given coin is 1/3. Then ...
... p(heads) = (1/3)·(1/2) + (1/3)·1 + (1/3)·(1/3) = 1/6 + 1/3 + 1/9 = (3 +6 + 2)/18
... p(heads) = 11/18
