The zeroes of the quadratic function f(x) = 6x² + 12x – 7 will be given below. Then the correct option is A.
<h3>What is a quadratic function ?</h3>
The quadratic function is given as ax² + bx + c = f(x).
For finding the zeroes of the polynomial we have to find the roots of the polynomial , The value of f(x) = 0
The given function is f(x) = 6x² + 12x – 7
Then the zeroes of the quadratic function will be
Here a =6 , b = 12 ,c = -7
Therefore the zeroes are
Therefore the correct option is A.

Answer:
An adult ticket is 17
A childs ticket costs 12 dollars
Step-by-step explanation:
Let a = adult price
c = child price
3a + 4c = 99
2a + 3c = 70
Multiply the first equation by 2
2(3a + 4c) = 99*2
6a + 8c = 198
Multiply the second equation by -3
-3 (2a + 3c) = 70*-3
-6a -9c = -210
Add these new equations together
6a + 8c = 198
-6a -9c = -210
----------------------
-c = -12
Multiply by -1
c = 12
A childs ticket costs 12 dollars
Now we need to find the price of an adult ticket
2a + 3c = 70
2a + 3(12) = 70
2a +36 = 70
Subtract 36 from each side
2a +36-36 =70-36
2a = 34
Divide by 2
2a/2 = 34/2
a = 17
An adult ticket is 17

Explanation: I’m takin the test to
Answer:
there both going at the same rate
Step-by-step explanation:
10 miles -1/4 hour
20 miles - 2/4 =1/2
30 miles - 3/4
B, 4x(2x2 + 3x)
divide both sides by 4 and you will get 2x2 + 3x to be the most factored form
