A mine extracts 2 tons of ore in an hour. Of the total ore extracted in a day, 4 tons is purchased by the government and more th

an 10 tons is sold to a mineral extractor. If the mine operates for x hours in a day, what is the simplest inequality that represents the number of hours the mine must operate to meet its obligations?

8 0

they sell 4 and more than10 for a total of at least 14 tons

the mine extracts 2 ton per hour

 so 14/2 = 7 hours a day minimum

so the inequality should be x>7

Find the inverse function g(x) of the function f(x)=2x+1
choli [55]

Answer:

The inverse function is f(x) = (x - 1)/2

Step-by-step explanation:

To find the inverse of any function, start by switching the x and f(x) values.

f(x) = 2x + 1

x = 2f(x) + 1

Now solve for the new f(x). The result will be your inverse function.

x = 2f(x) + 1

x - 1 = 2f(x)

(x - 1)/2 = f(x)

2. 7x = 5 + 5x <br> solve
Tresset [83]

Answer:

x = 2\frac{1}{2} or \frac{5}{2}

Step-by-step explanation:

Subtract 5x from both sides. This leaves us with 2x = 5. Now divide both sides by 2 to isolate x. If you want an improper fraction you can stop at x = \frac{5}{2}. If you want a mixed number you will have x = 2\frac{1}{2}.

Write an equation in standard form of the line that passes through the given point and the given slope. (-9, -4); m = -1/3
tigry1 [53]
<h2>Answer:</h2>

First, we must determine <u><em>b</em></u> using <u><em>slope-intercept form*</em></u>, the given point, and the given slope.

-4 = -\frac{1}{3}(-9) + b\\\\-4 = -3 + b\\\\-1 = b

Second, we need to set up the equation of the line in slope-intercept form.

y = -\frac{1}{3}x - 1

Third, we convert the above equation to <em>STANDARD FORM**</em>.

y = -\frac{1}{3}x - 1\\\\\frac{1}{3}x + y = -1

We now have our equation: \frac{1}{3}x - y = -1

*Slope-intercept form: <em>y = mx + b</em>

**Standard form: <em>ax + by = c</em>
