Answer:
The answer for number 3 is 96.7 if you want the work shown I would recommend you to download the app Socratic and for number six you multiply.75x14 then also multiply.35x7 then add add up the answers which will be 12.95 then you subtract that from 15 the answer is $2.05
Answer:
x² - 6x - 2 +
Step-by-step explanation:
In the quadratic equation y = ax² + bx + c, the axis of symmetry can be determined with
x = -b/2a
Solution:
Identify the coefficient of the quadratic equation y = 3x² - 6x - 4
a = 3
b = -6
c = -4
The axis symmetry will be
x = -b / 2a
x = -(-6) / 2(3)
x = 6/6
x = 1
The axis of symmetry is x = 1
