At Binh's Greenhouse in early spring, there are many greenhouse plants to repot and many outside plants to water. If it takes Bi

nh 5 minutes to repot each plant and 2 minutes to water each plant, and he has at most 2 hours before the greenhouse opens, what inequality represents the time Binh has to repot and water the plants before the greenhouse opens? Let x represent the number of plants to repot, and y represent the number of plants to water.

2*y + 5*x < 2 hours But the units are not the same. The left side contains minutes and the right hours.

2y + 5x < 2*60

Answer:

5x + 2x < 120

Step-by-step explanation:

Given:

Binh takes 5 minutes to repot each plant and 2 minutes to water each plant.

He has at most 2 hours.

Here "at most" represents by the inequality "<"

Let's convert 2 hours into minutes.

1 hour = 60 minutes

2 hours = 2×60 minutes = 120 minutes

Let x represent the number of plants to repot, and y represent the number of plants to water.

So, the given situation represented by

5x + 2x < 120

Dafna11 [192]

Let <em>f(x)</em> = <em>x</em>³ + <em>x</em> - 5. <em>f(x)</em> is a polynomial so it's continuous everywhere on its domain (all real numbers). Since

<em>f</em> (1) = 1³ + 1 - 5 = -3 < 0

and

<em>f</em> (2) = 2³ + 2 - 5 = 5 > 0

it follows by the intermediate value theorem that there at least one number <em>x</em> = <em>c</em> between 1 and 2 for which <em>f(c)</em> = 0.

Which linear inequality is represented by the graph?​
zalisa [80]

Answer:

y ≥ \frac{1}{3}x - 1

Step-by-step explanation:

First, determine the slope of the line. We can see that the slope is \frac{1}{3}, because the slope has less than 1 y interval per every x interval. This means that the line is less steep. There are only 2 slope choices, \frac{1}{3}, -\frac{1}{3}\\, and 3. We can tell that the slope is positive, but it must be \frac{1}{3}\\ because it is clearly less steep than a 3 slope line.

Now, look at the portion that is shaded. It is above the line, and this means that y is greater than the equation given. We can tell it is greater than or equal to, because the line that represents the equation is shaded as well. If it was only greater than and not equal to, the line would not be shaded.

Hope this helps ! :) Please feel free to ask me any questions!
