In inequality 20 >= 4/5 w, w is 25 or any real no. lower than< 25 and in inequality -8<-1/4m, m = any real no. greater than> 24 is are the solution.
What is inequality?An inequality compares two values and indicates whether one is lower, higher, or simply not equal to the other.
A B declares that a B is not equal.
When a and b are equal, an is less than b.
If a > b, then an is bigger than b.
(those two are called strict inequality)
The phrase "a b" denotes that an is less than or equal to b.
The phrase "a > b" denotes that an is greater than or equal to b.
We have give the inequality to solve
20 = 4/5w
w = 20 × 5/4
= 25 or any real no. lower than< 25
Let -8 = -1/4m

Write the equation in standard form for the circle passing through (2,3) centered at the origin
Given
coordinates (2, 3) and centre points (0,0)
Find
Equation of a circle
Explanation
As we know the standard equation for a circle with centre (h , k ) and r is a radius
[tex](x-h)^2+(y-k)^2=r^2[/tex]since, center is (0 , 0) , the equation becomes
[tex]x^2+y^2=r^2[/tex]Now, we find the value of radius , it is can find by using the pythagoras theorem,
[tex]r^2=2^2+3^2=4+9=13[/tex]so,
[tex]x^2+y^2=13[/tex]Final Answer
The equation for a circle passing through (2, 3) is

What is polynomial ?Polynomials are algebraic expressions with variables and coefficients. Variables are also known as indeterminates. For polynomial expressions, we can perform arithmetic operations such as addition, subtraction, multiplication, and positive integer exponents, but not division by variable.The variables and exponents of polynomials do not change when they are subtracted. Only their coefficients are subject to change. This ensures that the difference has variables and exponents that are already classified as polynomials. As a result, the difference is always a polynomial.Consider two polynomials,
(9x² + 8x) and (2x² + 3x)
The difference of polynomials is,
(9x² + 8x) - (2x²+ 3x)
9x² + 8x - 2x²+ 3x
= 7x² + 8x - 3x
= 7x² + 5x
Simplifying we get ,

Based on the triangle inequality theorem, the set of side measurements that could be used to form a triangle is: D. 5, 11, 8.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that three set of side measurements, a, b, and c would form a triangle if a + b > c, that is, the sum of any of two sides should be greater than the third side.
The set of side of measurements 5, 11, 8 will form a triangle because:
5 + 11 > 8 ⇒ 16 > 8
5 + 8 > 11 ⇒ 13 > 11
8 + 11 > 5 ⇒ 19 > 8

Given,
angle I = 54 degrees
angle FBC = 44 degrees
Recall, the sum of the angles in a triangle is 180 degrees. This means that for triangle BIC,
angle B + angle I + angle BCI = 180 degrees
54 + 44 + angle BCI = 180
angle BCI + 98 = 180
angle BCI = 180 - 98 = 82(sum of angles in a triangle)
Since lines AD and EH are parallel,
angle BCI and angle FGI are corresponding angles(They have similar positions and lie on the same side of the transversal, CI)
Thus,
angle FGI = 82(corresponding angles)

To determine which option is a representation of the graph we need to make the numer line analysis; to make it we need to notice that the functions has zeros at the points:
[tex]\begin{gathered} x=2 \\ x=4 \\ x=-3 \\ x=0 \end{gathered}[/tex]once we know this we divide the number line in the following intervals:
now we need check the sign of the function in each interval, to do this we choose a value in them.
For the first interval let's take x=-4, then we have:
[tex]\begin{gathered} f(-4)=-(-4)^3(-4-2)^2(-4-4)(-4+3) \\ f(-4)=-(-64)(36)(-8)(-1) \\ f(-4)=(64)(36)(8) \\ f(-4)=18432 \end{gathered}[/tex]From the last expression we notice that the value of the function is positive at this point. Hence the firts interval have positive values for the function.
For the second interval let's take x=-1, then we have:
[tex]\begin{gathered} f(-1)=-(-1)^3(-1-2)^2(-1-4)(-1+3) \\ f(-1)=-(-1)(9)(-5)(2) \\ f(-1)=-90 \end{gathered}[/tex]From the result we conclude that the function is negative in this interval.
For the third interval, let's take x=1, we have:
[tex]\begin{gathered} f(1)=-(1)^3(1-2)^2(1-4)(1+3) \\ f(1)=-(1)(1)(-3)(-4) \\ f(1)=12 \end{gathered}[/tex]From the result we conclude that the function is positive in this interval.
For the fourth interval, let's take x=3. then we have:
[tex]\begin{gathered} f(3)=-(3)^3(3-2)^2(3-4)(3+3) \\ f(3)=-(27)(1)(-1)(6) \\ f(3)=162 \end{gathered}[/tex]Then the function is positive in this interval.
Finally, for the fifth interval let's take x=5, then we have:
[tex]\begin{gathered} f(5)=-(5)^3(5-2)^2(5-4)(5+3) \\ f(5)=-(125)(9)(1)(8) \\ f(1)=-9000 \end{gathered}[/tex]Then the function is negative in the last interval.
Hence the line analysis is:
The y-intercept of the function happens when x=0, then we have that:
[tex]\begin{gathered} f(0)=-(0)^3(0-2)^2(0-4)(0+3) \\ f(0)=0 \end{gathered}[/tex]Therefore the y-intercept of the function is 0.
Once we know the information from the line analysis and the y-intercept of the function we conclude that the sketch of the graph is option B.
Two graphs of the function (with different values for the y-axis) are shown below:
This graphs confirm that option B is an approximate sketch of the graph.
A science class is going on a field trip to a museum. The school hires vans to take the students to the museum. Each van can hold a maximum 11 people including
passengers and driver
If there are a total of 30 students going on the field trip, which inequality represents the number of vans, V. that will be needed?
Answer: 3 Vans are needed.
Step-by-step explanation:
There are 30 students so already you need 3 vans, if you only have 2 vans, you will be leaving behind 10 students so regardless you need a 3rd van. with 3 vans you can hold 33 people. 30 students+ 3 drivers=33 people.
The inequality that represents the number of vans for the given case is V ≤ 30/11.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
Suppose the number of vans be V.
The number of students for each van is 11.
And, the total number of students is 30.
Now, the inequality for the number of vans can be written as,
11V ≤ 30
⇒ V ≤ 30/11
Hence, the inequality for the number of vans is given as V ≤ 30/11.
