The maximum profit is the highest point on the curve at (3, 45), and since the y-value is the profit in hundreds of dollars, the maximum profit is $4500.
The shop is making a profit as long as the curve is above the x-axis, so this is over the given interval (0, 10).
The maximum profit is earned at x = 3, and the x-value is the money spent on advertising in hundreds of dollars, so this means that $300 was spent of advertising.

Which number line represents the solution set for the inequality –4(x 3) ≤ –2 – 2x?

Anna71 [15]

The solution to the inequality expression is x ≥ - 5

<h3>Inequality expressions</h3>

Inequality are expressions not separated by an equal sign. Given the inequality;

–4(x + 3) ≤ –2 – 2x

Expand

-4x - 12 ≤ -2 - 2x

Collect the like terms

-4x + 2x ≤ -2 + 12

-2x ≤ 10

Divide both sides by -2

-2x/-2 ≤ 10/-2
x ≥ - 5

Hence the solution to the inequality expression is x ≥ - 5
