Answer: C (21)
Step-by-step explanation:
I am translating into algebra.
Set Scott's age five years ago to: x
Set Paul's age five years ago to: 2x-4
Scott's age now is his age five years ago, plus five, which is: x+5
Paul's age now is his age five years ago, plus five, which is: 2x-4+5 or 2x+1
Since Paul is now six years older than Scott, set Scott's age (x+5) equal to Paul's age, plus six, which is: 2x+1=x+5+6
Solve the equation to get: x=10
Substitute x for 10 in Paul's current age: 2*10+1=21.
Therefore, C is the correct answer.
In the graph of quadratic equation, the parabola passes through the points left parenthesis (-2,0) right parenthesis, left parenthesis (0,-4) right parenthesis, and left parenthesis (2,0) right parenthesis.
<h3>What is a quadratic equation?</h3>A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.
The standard form of the quadratic equation is,
Here,(a,b, c) is the real numbers and (x) is the variable.
The given quadratic equation is,
Equate the equation to zero to solve it further,
Thus, the solution of the equation is +2 and -2. The graph of the equation is attached below.
Hence, in the graph of quadratic equation, the parabola passes through the points left parenthesis (-2,0) right parenthesis, left parenthesis (0,-4) right parenthesis, and left parenthesis (2,0) right parenthesis.
