Answer:
x = 45
Step-by-step explanation:
0.36(18) + 0.04x = 0.12(24 + x)
6.48 + 0.04x = 2.88 + 0.12x
0.04x - 0.12x = 2.88 - 6.48
-0.08x = -3.6
0.08x = 3.6
x = 3.6/0.08
x = 45
Answer:
x = -2
Step-by-step explanation:
-6x + 5 = 17
First, combine the constants by subtracting 5 from each side.
-6x = 17 - 5
-6x = 12
Now you want x by itself, so divide both sides by -6.
x = -2
Check your answer by plugging x = -2 into the original equation.
-6(-2) + 5 = 17
12 + 5 = 17
17 = 17
Your answer is correct.
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}
Add up all like factors so just add all of them up
