The <em>correct answer</em> is:
$30.
Explanation:
Writing the transaction amounts as signed integers, we have:
+30, -20, -30, +40, -50
We want to add these together. Addition is commutative, which means we can add the positive integers before the negative:
30+40+(-20)+(-30)+(-50)
70+(-20)+(-30)+(-50)
We can now add the negative integers together:
70+(-50)+(-50)
70+(-100)
Adding these together, we have
-30
This means we would need at least $30 to avoid overdrafting the account.
A man has 21 sheep, one out of every 4 are red, how many are red
21/4 = 5.25
A man has 21 bricks he glues every 4 pieces together how many pieces does he have now
21/4 = 5.25

Answer:
see explanation
Step-by-step explanation:
Given
y = 3(x - 3)(x - 2)
To find the x- intercepts, let y = 0, that is
3(x - 3)(x - 2) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 2 = 0 ⇒ x = 2
Thus the x- intercepts are x = 2 and x = 3
To find the y- intercept let x = 0 and equate for y, that is
y = 3(0 - 3)(0 - 2) = 3(- 3)(- 2) = 3 × 6 = 18
Thus the y- intercept is y = 18
