Answer:


Step-by-step explanation:
Given:
The given expressions are.

We need to find x and y values.
Solution:
Equation 1⇒
Equation 2⇒ 
First solve the equation 1 for y.
--------(3)
Substitute
in equation 2.

Simplify.



Add 16 both side of the equation.



Divide Numerator and denominator by 5.

Substitute x value in equation 3 and simplify.





.
Therefore, the value of
and
.
Using the formula 1° × π/180 = 0.01745rad,
3240 degrees/second = 56.54867 radians/seconds
Answer:
a=1
b=2
c=-8
y-intercept: (0, -8)
Line of symmetry calculation: x = -2/(2*1)
Line of symmetry: -1
Opens up because a > 0
Minimum
Vertex: (-1, -9)
Domain: -∞ < x < ∞ (no domain constraints)
Range: [-9, ∞]
