we have that
Step 1
<u>Find the y-intercept</u>
we know that
The y-intercept is the value of f(x) when the value of x is equal to zero
For 
Point 
Step 2
<u>Find the value of f(x) for 
</u>
Point 
Step 3
<u>Graph the point A and B to find the solution</u>
therefore
the answer in the attached figure
Answer:
-2 a
Step-by-step explanation:
I think you are referring to the (square root of b^2 - 4ac) in the quadratic formula.
When b^2 - 4ac is less than zero, the solutions to the quadratic equation will be complex (iamginary).
Answer:
5x+ 4
Step-by-step explanation:
First, put all of the x variables together. So 3x+4x=7x
7x + 4 -2x Since the 2x is negative you can subtract it from 7x and get 5x.
you can not add the four to the 5x because it does not have a matching variable.
So, you have: 5x+ 4
This is the best I got Require to make 2 equations with the same repeating part and subtract them to eliminate the repeating part.
begin by letting x = 0.5555555................. (1)
To obtain the same repeating part after the decimal point need to multiply by 10
hence 10x = 5.555555........................(2)
It is important to obtain 2 equations in x, where the recurring part after the decimal points are exactly the same.
now subtract (1) from (2) to obtain fraction
(2) - (1) : <span>9x=5⇒x=<span><span>59</span></span></span>
