How do you decide where to shade an inequality whose boundary does not go through the origin?
Answer:
If it does not satisfy the inequality, shade the region which does not contain that point. All the points in the shaded region will satisfy the inequality. Note: The origin (0, 0) is usually the easiest point to test, provided it is not on the line.
Inequalities are used to represent unequal expressions.
The region to shade are the region that satisfy the inequality.
Take for instance the following inequality
[tex]\mathbf{y \ge 2x + 5}[/tex]
The above inequality represents greater than or equal to.
This means that, the regions that satisfy the inequality are the region on the line of [tex]\mathbf{y \ge 2x + 5}[/tex] and the areas above it.
If the inequality is less than, then the region below the line of the inequality will be shaded.

Answer:
Step-by-step explanation:
I am assuming that number began with a decimal point.
Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes

Given a set of attributes, can you make one triangle, no triangles, or many triangles?
jo says, "the attributes of my triangle are sides that are 3cm and 9cm long. I can make only one triangle because I have to connect the ends of my two sides."
do you agree or disagree? why?
Answer:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
In the figure below, triangle JKL is isosceles, with JK = LK, and triangle LMN is equilateral. K M M N L Note: picture not drawn to scale If m<ZJKL = 32, what is m<ZKLM? A 56 B. 41 C. 51 D. 46

What property of operations can be used to justify that the two expressions in this equation are equivalent? 6x^2 +4x=4x + 6x^2
Answer:
Commutative
Step-by-step explanation:
There are four basic property of operations to solve an algebraic expressions. They are associative, commutative, distributive and identity.
The expression given is : [tex]$6x^2 + 4x=4x+6x^2$[/tex]
So the given algebraic expression is a commutative property of operations. The commutative property states that when any two numbers are added in an expression the sum of the numbers are the same regardless of the order of the numbers that are added.
Thus the sum of the above expression will be same in which ever order the numbers are added.

The area of the circle is equal to 144π square inches.
What is the area of the circle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that the circumference of a circle is 24π in. The area of the circle is calculated by the formula given below,
Area of circle = πr²
Circumference of the circle = 24π
2πr = 24π
r = 12
The area of the circle will be calculated as:-
Area = πr²
Area = π x ( 12 )²
Area = 144π square inches.
Hence, the area is 144π square inches.

Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter

Step-by Step
500.00-375.00 = 125.00
5000 x 2.5% = 125.00
375.00 + 125.00 = 500.00
The volume of clay sculpture is 540 cubic inches.What is the volume of similar sculpture that is smaller by a scale factor of 1/2.
Answer:
67.5 in³
Step-by-step explanation:
Given that :
Volume 1 = 540 in³
Volume 2 of similar shape = x ; if the scale factor = 1/2
Volume of a shape = length * width * height)
The scale factor = 1/2
Volumetric factor = 1/2 * 1/2 * 1/2 = 1/8
Hence, the volume of similar sculpture will be :
540 in³ * 1/8 = 67.5 in³

Answer:
x= -7

-4x = - 8 + 36
-4x= 28
x= 28/-4
x= - 7
Can someone help me on this please? X/4=-12 this says x divided by 2 equals -8. Explain how you would solve for x and what you would get.
Answer:
-48 ; - 16
Step-by-step explanation:
Given the expression :
X /4 = - 12
Multiply both sides by 4
X/4 * 4 = - 12 * 4
X = - 48
For the second :
X/2 = - 8
Multiply both sides by 2
X/2 * 2 = - 8 * 2
X = - 16

Step-by-step explanation:
How would you do this maths question?
Answer:
Step-by-step explanation:
First you take the 142+B=180
because those 2 are supplementary
B=38
and you see the 2 lines on the 2 sides that means those two sides are equal to each other and the angles corresponding with them are also equal to each other.
and a triangle= 180 degrees
A and E are the same so A=E
180-B(38)= 142
and because A=E you do 142/2= 71
and now that you have A and E you don't need A or B for the last part so
E+(x)=180 because those two angles are supplementary.
and E is 71 so...
71+(x)=180 ---------180-71=x
X=109

Step-by-step explanation:
i kinda dont know what your asking but i tried
The common prime factor of the numbers 77 and 242? will be 11.
What is a prime factor?A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,
Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,
77 / 11 = 7
242 / 11 = 22
Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.
