Step-by-step explanation:
Answer:
Step-by-step explanation:
90x - 60y = 68.....multiply by -1
90x - 70y = 91
---------------------------
-90x + 60y = -68 (result of multiplying by -1)
90x - 70y = 91
---------------------------add
-10y = 23
y = -23/10 <===
90x - 60y = 68
90x - 60(-23/10) = 68
90x + 138 = 68
90x = 68 - 138
90x = - 70
x = -70/90
x = -7/9 <=====

Answer: The axis of symmetry is x=1.
Explanation:
The given function is,
The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.
The axis of symmetry of a parabolic function is a vertical line,
Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,
Therefore, the axis of symmetry is x=1.
A)1:2
b)21:2
c)6:44 or 3:22
d)2:5
