How do you do this?
Write a system of inequalities to describe the
shaded region.
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

What is the base when the expression (-1.5)2 • (3.2)5 is written as a single power of 5?
we can rewrite:
(-1.5)²*(3.2)⁵ = 3.76⁵
The new base of the expression is 3.76
What is the new base of the expression?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

What is a Triangle?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

Please choose all of the transformations that she can use to create a congruent image.
Fun fact: Kamama is a Cherokee name meaning Butterfly.

Based on the fact that Kamama wants her hexagons to be congruent, the transformations that she can use are:
ReflectionTranslationRotationWhat transformations give congruent shapes?In order to have congruent shapes, there are three transformations that can be used.
Firstly, it is important to note that congruent shapes have the same size and the same shape. They are identical except for their orientation which may be different.
A reflection would create a congruent shape that would have the same size and angles but the orientation should be different. This is the same as a rotation. A translation will often result in congruent shapes that also have the same orientation. This means that Kanama can use any of these transformations.

The area of the figure is
square units.
Answer:
80 square units
Step-by-step explanation:
The figure given can be decomposed to have two trapezoids of equal dimensions and a rectangle.
Area of the figure = (2*area of a trapezoid) + (area of a rectangle)
Area of the 2 trapezoids:
Area of the two trapezoid = 2(½(a + b)*h)
Where,
a = 2 + 6 + 2 = 10 units
b = 6 units
h = 2 units
Plug in the values:
Area of the two trapezoid = 2(½(10 + 6)*2)
= 2(½(16)*2)
Area = 32 units²
Area of the rectangle:
Area = length × width
Length = 8 units
Width = 6 units
Area = 8 × 6 = 48 units²
✔️Area of the figure = 32 + 48 = 80 units²

The bill for Mr. Wilson’s diner meal is $25.50. As a tip, Mr. Wilson gives the server 20% of the meal’s cost. What is the total amount Mr. Wilson’s pays, including tip?
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)

Step-by-step explanation:
Write the equation for line L in point-slope form and slope-intercept form
L is perpendicular to y=2x
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)
How to represent equation in slope intercept form and point slope form?
The equation in a slope intercept form is represented as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, 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
m = slopex₁ and y₁ are the coordinatesTherefore, using (-2, -4),
(y + 4) = - 1 / 2 (x + 2)

25% discount for AED 4000
Answer:
The 25% discount on AED 4000 will be: 1000 AED
Step-by-step explanation:
Given
The amount = 4000Discount = 25%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
