We are given a graph of the system of inequalities.

Given system of inequalities:

1) y < 2x

y ≤ 1

2) y > 2x

y ≥ 1

3) y ≤ 2x

y < 1

4) y ≥ 2x

y > 1.

In the show graph, we can see that red shaded portion have a dotted line.

And the graph is shaded above the dotted line.

Because graph is shaded above the dotted line, it should be only greater than sign.

<h3>So, the inequality y > 1 would best fit for that above shaded portion of the graph.</h3><h3>We, can see in 4th option we have y > 1 ( y is greater than 1).</h3><h3>Therefore, correct option is 4th option :</h3><h3> y ≥ 2x</h3><h3>y > 1</h3>

A boat sails 20 miles wast of the port and then 15 miles south to an island how far is the boat from the port if you measure thr
sweet-ann [11.9K]

Answer:

25 miles

Step-by-step explanation:

Given: A boat sail 20 miles west of the port and then 15 miles south to an island.

Picture attached.

The distance from port to island could be measured in a straight line. It will form a hypotenous.

∴ we can use Pythogorean theorem to find the distance.

h^{2} = a^{2} +b^{2}

Where, "a" is adjacent= 20 miles and "b" is opposite= 15 miles.

h^{2} = 20^{2} +15^{2}

⇒ h^{2} = 400+225= 625

⇒h^{2} = 625

⇒h= \sqrt{625}= \sqrt{25^{2} }

We know \sqrt{x^{2} } = x.

∴h= 25\ miles

∴ Distance of Port from the Island is 25 miles.

2. How many real number solutions are there to the equation 0 =-3x2 + x - 4?
goblinko [34]

For this case we have the following quadratic equation:

-3x ^ 2 + x-4 = 0

Where:

a = -3\\b = 1\\c = -4

By definition, the discriminant of a quadratic equation is given by:

d = b ^ 2-4 (a) (c)

We have to:

d> 0: Two different real roots

dTwo different complex roots

d = 0: Two equal real roots

Substituting the values we have:

d = 1 ^ 2-4 (-3) (- 4)\\d = 1-48\\d = -47

So, we have two different complex roots

Answer:

Two different complex roots
