Answer:
Step-by-step explanation:
The equation of a quadratic function is given as:
ax² + bx + c = 0
where a, b and c are the coefficient in the quadratic equation.
The axis of symmetry of the quadratic equation is given as:
To get the equation for a, we have to make a the subject of formula:
Answer:
9 and -3
Step-by-step explanation:
Let the first number be x
Second number = y
x + y = 6
x = 15 - 2y
15 - 2y + y = 6
15 - y = 6
-y = 6 - 15
-y = -9 ( - sign gets cut cuz there is - sign at both the sides)
Therefore, first number = 9
x + y = 6
x = 9 = 6
x = -3
Therefore, second number = -3
Proof:
9 + (-3) = 6

54 is a common denominator between 1/6 and 1/9
6/8 I think

Answer:
b = 4
Step-by-step explanation:
4b + 5 = 1 + 5b
4b-5b + 5 = 1
4b-5b = 1 - 5
-b = 1 - 5
-b = -4
-b = -4
b - 4
