Where does the graph of y=-3x-18 intersect the x-axis

2 answers:

6 0

<span>a line crosses the x axis when y = 0
0 = -3x - 18

Add 3x to both sides
3x = -18

Divide both sides by 3
x = -6

Graph intersects x axis at point
(-6, 0)

Irina18 [472]

Answer:

$x \in (40,110)$

Step-by-step explanation:

We are given the following in the question:

$p(x)=-x ^2 + 150 x - 4400$

where p gives the profit.

We want to keep the profit positive, thus

$p(x)=-x ^2 + 150 x - 4400 > 0\\-x ^2 + 150 x - 4400 > 0\\x^2-150x+4400$

Thus, x should lie between 40 and 110 so that the profit is always positive.
