The value of “k” that will give two real roots is 25/48
Given the equation (1 – 3k) x^2 + 3x – 4, for the equation to have two real roots, this means that b^2 - 4ac > 0
From the given expression
a = 1 - 3k
b = 3
c = -4
Substitute into the equation b^2 - 4ac = 0
3^2 - 4(1 - 3k)(-4) = 0
9 + 16 (1-3k) = 0
9 + 16 - 48k =0
25 = 48k
k = 25/48
Hence the value of “k” that will give two real roots is 25/48

Answer:
no, Sara subtracted 2x on one side and added 2x on the other side
Step-by-step explanation:
The addition property of equality requires that the same value be added to both sides of an equation.
Sara wants to remove the -2x term from the right side of the equation, so rightfully adds 2x to that side of the equation. According to the addition property of equality, she must also add 2x to the left side of the equation. This will give her ...
5x ≤ 2
x ≤ 2/5 . . . . divide both sides by 5
240 melons
First, multiply the # of boxes and # of bags
(30 * 4 = 120)
Then, multiply that with 2
(120*2=240)
Thus, the store has 240 melons .
