First, you set your problem up like this:
-4x+3=2x-6
add 6 to both sides so it looks like this:
-4x+9=2x
add 4x to both sides so it looks like this:
9=6x
divide 6 from both sides so this is your answer:
1.5=x
C
6x^2-13X-5=0
(3X+1)(2X-5)
3x-1=0
X=1/3. 2x-5=0. X= 5/2
Answer:
$14.80
Step-by-step explanation:
I'm assuming you meant to put 3.20 since $320 a mile would be ridiculous.
C(n)=2.00+3.20n
If n = 4 miles we have:
C(4)=2+3.20(4)
C(4)=2+12.80
C(4)=14.80
So the cost of the taxi is $14.80.
The answer to your question is 7a.
