Answer:

The correct answer is:

Option A: A 10x — 15000 ≥ 50000

Step-by-step explanation:

Given that the total cost of manufacturing by the company is $15000.

Let x be the number of gallons the company sells.

It is also mentioned that the company earns $10 on each gallon.

So the total profit will be the the difference of the selling cost of gallons and manufacturing cost

Mathematically,

$10x-15000$

Now it is mentioned that the profit should be at least 50000 dollars which means the profit can be minimally 50000 and also can be greater than it so

$10x-15000 \geq 50000$

The number of gallons can be found by solving the obtained inequality.

Hence,

The correct answer is:

Option A: A 10x — 15000 ≥ 50000

Whats the slope intercept for x-8y=-6

suter [353]

The slope-intercept form of a line is in the form y = mx + b. So basically if you want to put the equation of a line in slope-intercept form, you solve for y.
x - 8y = -6
-8y = -x - 6
y = (1/8)x + 3/4
