Essentially when people ask you find the solution to system of equation, there asking at what x value do these to graphs intersect. The easiest way to do this is to get a graphing calculator, or desmos and type in the equation and find where they intersect. Heck, even the question says to solve it with a graph, but I'll demonstrate it algebraically.
One way you can do this is set the equation equal to each other. This is because you want to know at what x-value has the same y-value. So we get:
x^2 + 6x + 8 = x + 4
We can then combine like terms, or move everything to one side. So we get:
x^2 + 5x + 4 = 0.
Then we can use the quadratic formula to solve for x.
x=(-5 +/- sqrt(5^2 - 4(1)(4)))/(2(1)
This simplifies into:
(-5 +/- 3)/2
Finally we add and subtract:
(-5 + 3)/2 = x = -1
(-5 - 3)/2 = x = -4
And our solution is x = -1, x = -4

Answer:
Option C is correct ,14.2%
Step-by-step explanation:
In order to determine the effective tax rate of a taxpayer with taxable income of $52,000,the starting point to determine how much in taxes the taxpayer pays as shown below:
First tax bracket=$9,525*10%=$952.5
Second tax bracket=$952.50+(12%*($38700-$9,525))
=$952.50+$3501
Third tax bracket(where the taxpayer belongs)=4453.5
+(22%*($52,000-$38,700))
third tax bracket tax=4453.5+$2926
=$7379.5
Since the total tax payable of $7379.5 is now computed,
effective tax rate=tax paid/taxable income=7379.5/52000
=14.2%
