Answer:
x=-4 x=-1
Step-by-step explanation:
y=x^2+5x+4
To find the x intercepts, set the equation equal to zero
0 = x^2+5x+4
Factor the equation
What 2 numbers multiply to 4 and add to 5
4*1 = 4
4+1 =5
0 =(x+4) (x+1)
Using the zero product property
x+4 =0 x+1=0
x=-4 x=-1
These are the x intercepts
Here , we have been asked to find sum of the expression
Here we have two different units , so we will convert it to one after adding
<span>Let us start with the percentage of premium paid by Javier. Since the employer pays 43%, the remaining 57% (100-43) is paid by Javier. Now let us find out how much is deducted from his paychecks during the year. In one month, $157.38 x 2 = $314 .76 is deducted by the employer. So in 12 months, the amount equal to 57% of the health premium will be $314.76 x 12 = $3777.12.
If $ 3777.12 is 57% of a certain number, to find the number, multiply $3777.12 with the reciprocal of the fraction. (57/100)
So the unknown number = $3777.12 * 100/57 = $6626.53
Javier's total annual health premium, therefore, is $6626.53</span>
