Answer:

In Explanation.

Step-by-step explanation:

In situations like this, you want to first find the equations of the individual lines.

Let's start with the left one.

It has a negative slope of 2 while it has a y-intercept of 1

y=-2x+1

is the equation.

The other line has a slope of 3/2.

The y-intercept is not visible, so we need to use point slope form.

I chose (2,-3)

y+3=3/2(x-2)

Simplify.

y=3x/2-3-3

y=3x/2-6

so we have

y=-2x+1

and

y=[tex]\frac{3x}{2}[/tex]-6

Since both lines are solid, the signs are ≥ or ≤

The shadings intersect above both lines so the individual shadings also have to be above the line.

That means the equation is less than the "y".

y≥-2x+1

y≥[tex]\frac{3x}{2}[/tex]-6

The equation of the line in slope intercept form is y = - 1 / 2 x - 5

The equation of the line in point slope form is (y + 4) = - 1 / 2 (x + 2)

The equation in a slope intercept form is represented as follows:

y = mx + b

where

Therefore, let's find the equation of the line L in slope intercept form.

The line L is perpendicular to y = 2x

Hence,

m₁m₂ = -1

2m₂ = -1

m₂ = -1 / 2

Therefore,

y = - 1 / 2 x + b

let's find b using (-2, -4)

-4 = - 1 / 2 (-2) + b

b = -4 - 1

b = -5

Hence, the equation of the line in slope intercept form is as follows:

y = - 1 / 2 x - 5

The equation of the line in point slope form is represented as follows:

(y - y₁) = m(x - x₁)

where

Therefore, using (-2, -4),

(y + 4) = - 1 / 2 (x + 2)

Step-by-step explanation:

8⁰ = 1

8¹ = 8

8² = 64

8³ = 512

8⁴ = 4096

8⁵ = 32768 > 6467

We have

6467 ÷ 8⁴ = 1 (mod 2371)

2371 ÷ 8³ = 4 (mod 323)

323 ÷ 8² = 5 (mod 3)

3 ÷ 8 = 0 (mod 3)

3 ÷ 1 = 3

=> 6467 in the base-eight system: 30541

Answer: i think u got it write its that one

Step-by-step explanation:

we can rewrite:

(-1.5)²*(3.2)⁵ = 3.76⁵

The new base of the expression is 3.76

Here we have the expression:

(-1.5)²*(3.2)⁵

And we want to write this as a single expression with a power of 5.

First we can rewrite:

(-1.5)² = x⁵

x = (-1.5)^(2/5)

Then the new base of the expression will be:

x*3.2

(-1.5)^(2/5)*3.2 = 3.76

Then we can rewrite:

(-1.5)²*(3.2)⁵ = 3.76⁵

The new base of the expression is 3.76

The lengths of the legs of the right triangle from the coordinates will be 2.24 units.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x - h)² + (y - k)²

Vega uses a coordinate system using yards as the units to create a map of a park that is situated on her street. A park seat is located at position (-1, 1) and the park gate is located at (1, 2).

Then the lengths of the legs of the right triangle from the coordinates will be

D² = (1 + 1)² + (2 - 1)²

D² = 2² + 1²

D² = 4 + 1

Answer:

$30.60

Step-by-step explanation:

What we know:

The bill for Mr. Wilson's diner meal is $25.50.

He gives a 20% tip to the waiter.

To figure out this tip, multiply 1/5 by 25.5.

1/5 * 51/2

51/10 = $5.10 tip.

Here, it's asking for the total, including the $5.10 tip. So, add $5.10 to $25.50 for $30.60 total, including the tip.

(For a simpler method *multiply 6/5 by $25.5)

Answer:

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = 4/2 = 2

           b = 5

           c = x

plugin values into the formula:

2² + 5² = x²

x = √(2² + 5²)

x = √29

The length of the side x of the isosceles triangle is x = √29 units

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

The measure of side AB = AC = x

The measure of BC = 4 units

Now , let AD be the perpendicular bisector of the triangle and AD = 5 units

where the measure of BD = measure of CD

And , right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

So , the measure of x = √ ( AD )² + ( BD )²

x = √ ( 25 ) + ( 4 )

x = √29 units

Hence , the length of side of triangle is x = √29 units

Answer:

The 25% discount on AED 4000 will be: 1000 AED

Step-by-step explanation:

Given

In order to determine a 25% discount on the amount AED 4000, all we need means is to multiply 25/100 or (0.25) by 4000.

i.e

Discount amount = 25% of 4000

                             = 25/100 × 4000

                             = 0.25 × 4000

                             = 1000 AED

Thus, the 25% discount on AED 4000 will be: 1000 AED
