Solve the inequality: -1/4(x^2-4x+3)>0
Montano1993 [528]
Ok so assume that if you have
xy=0 then x and y=0
-1/4(x^2-4x+3)>0
multiply both sides by -4 to clear fraction (-4/-4=1)
flip sign
x^2-4x+3<0
factor
(x-3)(x-1)<0

we know that (+) times (-)=(-) and 
(-) times (-)=(+) so we don't want them to be both negative, we want different sign
we cannnot have 3 since it would be (0)(2)<0 which is false
we cannot have 1 either since (-2)(0)<0 is also false
lets see if the solution is in betwen 3 and 1 or outside of 3 and 1
ltry 2
2^3-4(2)+3<0
8-8+3<0
3<0
false
therefor it is outside ie
x>3 and x<1

Mark bought a notebook for $1.45 and some pencils for $0.42 each. If the total cost was $6.91, how many pencils did he buy?
Lesechka [4]
B - 13

Okay, we know that Mark brought 1 notebook and the totally is 6.91 while one pencil costs $0.42.

x= number of pencils he brought.
we know the price of 1 notebook + the cost of pencils times the numbers of pencils he brought = total cost.

So the equation will be:

1.45 + 0.42x = 6.91  subtract 1.45 on both sides.
0.42x = 5.46   Then we solve for x by dividing both sides by 0.42
x= 13

So the number of pencils he brought is 13.
