Answer:
x = 5
Step-by-step explanation:
A quadratic equation:
f(x) = y = a*x^2 + b*x + c
Has a vertex in a point:
(h, k) such that:
h = -b/2a
and:
k = f(-b/2a)
And the axis of symmetry (this is the line that cuts the graph in two halves) is:
x = h.
In this case, the vertex is (5, -6)
Then the axis of symmetry is:
x = 5.
Answer: 5x+12=3x+18
Step-by-step explanation: let x = hours worked
Penny earns $5/hour + $12 fee so 5x+12
Charlene earns $3/hour + $18 fee so 3x+18
They are going to earn the same thing so 5x+12=3x+18
The discriminant is <span>−<span>8
</span></span>f<span>(x)</span>=−3<span>x2</span>−2x−1
is of the form <span><span>a<span>x2</span>+bx+c</span>
</span>,with <span><span>a=−3</span>
</span>, <span><span>b=−2</span>
</span> and <span>c=−<span>1</span></span>
