!) $18,000
<span>2) 1000 + 425(48) = $21,400 </span>
<span>3) 21,400 - 18,000 = $3400 </span>
<span>4) $23,500 </span>
<span>5) 2000 + 60(425) = $27,500 </span>
<span>6) 27,500 - 23,500 = $4000</span>
X= -2/5
SOLUTION
25x^2 + 20x + 4 = 0
(5x + 2)^2 = 0
5x + 2 = 0
x= -2/5
Hope this helps! :))
Answer:
Step-by-step explanation:
First you have to do everything in the brackets, or [ ]. -7+-3--8 is equivalent to 8-3-7, which equals -2. After that you have to do the braces, or {}. That is -5--2, which is the same thing as 2-5, which equals -3. Finally, you can finish it out. -4--2--3 is equivalent to 3+2-4, which equals 1. Hope this helps!
In order to find the<u> roots</u> of the cubic equations by <u>graphing</u> you have to follow those steps
we have
we know that
The <u>roots</u> of the function are the values of x when the value of the function is equal to zero
Using a <u>graphing </u>tool
see the attached figure
The<u> roots</u> are
therefore
the answer is
