What is inequality?
An inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Here given that,
Party favors are on sale for $[tex]2.40[/tex] each. You have $[tex]380[/tex] to spend on the decorations and gifts, and you have already spent $[tex]270[/tex] on decorating.
So,
[tex]380-270=[/tex] $[tex]110[/tex]
To find the number of party favors you can buy, we divide $[tex]110[/tex] by the favors that are on sale for $[tex]2.40[/tex] is
[tex]\frac{110}{2.40}[/tex] = $[tex]45[/tex]

which of the following values of x makes the rational expression below undefined? x-25/x+13
a. 13
b. 0
c. 25
d. -13
Answer:
Option D
Step-by-step explanation:
We will check each option for the given expression (x-25)/(x+13)
(A). for x = 13
[tex](\frac{x-25}{x+13})=\frac{13-25}{13+13} =\frac{-12}{26}[/tex]
So expression is defined.
(B). for x = 0
[tex]\frac{x-25}{x+13}=\frac{0-25}{0+13} =(\frac{-25}{13})[/tex]
So expression is defined.
(C). For x = 25
[tex](\frac{x-25}{x+13})=\frac{25-25}{25+13} =0[/tex]
So expression is defined
(D). For x = -13
[tex]\frac{x-25}{x+13}=\frac{-13-25}{-13+13}=( \frac{-38}{0})[/tex]
Function is not defined.
Option D is the answer.
please translate 2 minus the product of a number and 9 is 20.
The statement '2 minus the product of a number and 9 is 20' translates to the equation 2 - 9x = 20. Solving for x, we find the solution x = -2, meaning the number in question is -2.
The student is asking to translate the phrase '2 minus the product of a number and 9 is 20' into a mathematical equation. The 'product of a number and 9' can be represented as '9x' where 'x' is the unknown number. Therefore, translating the entire phrase, we end up with the equation: 2 - 9x = 20.
To solve for 'x', we first bring '9x' to the other side of the equation by adding '9x' to both sides, resulting in 2 = 9x + 20. Subsequently, we subtract 20 from both sides, yielding -18 = 9x, and then we divide both sides by 9 to find the value of 'x'. So, x = -18 / 9, which simplifies to x = -2.
The solution for the equation is x = -2, which means the number we were looking for is -2.

An athlete whose event is the shot put releases a shot. When the shot whose path is shown by the graph to the right is released at an angle of 70°, it's height, f(x), in feet, can be modeled by:
[tex]f(x)=-0.06x^2 + 2.7x + 5.9[/tex]
where x is the shot's horizontal distance, in feet, from its point of release.
What is the maximum height of the shot and how far from it's point of release does this occur?
The maximum height reached by the shot is 36.375 feet. This occurs at a horizontal distance of 22.5 feet from its point of release.
Explanation:This is a question about the maximum height of a shot put. The equation presented here is a quadratic function, and it has the form of a parabola. The maximum value of a parabola that opens downwards (as in this case, where the coefficient of x2 is negative) is given at its vertex.
To find the 'x' coordinate of the vertex, use the formula -b/2a, where 'a' is the coefficient of x2 and 'b' is the coefficient of 'x'. In this case, 'a' is -0.06, and 'b' is 2.7. -b/2a = -(2.7)/(2*-0.06) equals 22.5 feet. This is the horizontal distance from the point of release where the shot reaches the maximum height. To find the maximum height, substitute the value of 'x' into the equation, f(22.5) = -0.06*(22.5)2 + 2.7*22.5 + 5.9. This gives the maximum height as 36.375 feet.Learn more about Maximum Height of Shot here:

Given: LM ∥ KN , KL ∥ NM LP = h1 = 5 cm, MQ = h2 = 6 cm PKLMN = 42 cm Find: Area of KLMN
Answer:
Area = 630/11 cm² = 57 3/11 cm²
Step-by-step explanation:
Area = (5 cm)(KN) = (6 cm)(KL)
Perimeter = 2(KN +KL) = 42 cm
So, ...
KN = 1.2·KL . . . . divide the area equation by 5 cm
1.2·KL +KL = 21 cm . . . . . divide the perimeter equation by 2
KL = (21 cm)/2.2 . . . . . . . divide by the coefficient of KL
Substituting for KL in the area equation, we have ...

The solution to the expression log₅ ( 2 )+ log₅( 10 ) - log₅( 4 ) is 1. Option B is correct.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The expression is calculated as:-
E = log₅ ( 2 )+ log₅( 10 ) - log₅( 4 )
Use Logarithmic property Loga(x / y ) = Loga(x) - Loga(y)
E = log₅ ( 2 ) + log₅( 10 / 4 )
Use Logarithmic property Loga(x y ) = Loga(x) + Loga(y)
E = log₅ [ 2 x ( 10 / 4 ) ]

find the values of x and y in the following equation. (x + yi) + (4 + 9) = 9 -4i
In this question we solve the given complex number equation. By comparing real and complex components on both sides of the equation, we find the values satisfying the equation are x = 5 and y=-13.
Explanation:In this complex number equation, we must solve for x and y: (x + yi) + (4 + 9) = 9 -4i. Begin by simplifying the left side of the equation, to give (x + 4 + yi +9i) = 9 - 4i. This further simplifies to (x + 4) + (y + 9)i = 9 -4i.
Now we can see that the real component of the equation (x + 4) must equal the real component on the other side of the equation (9), and the complex component of the equation (y + 9)i must equal the complex component -4i. Setting these equal gives x + 4 = 9 and y + 9 = -4.
Solving these gives x = 5 and y = -13, which are the values for x and y satisfying the equation.

Melissa bought a cake that cost $75. the sales-tax rate is 10 percent. what is the total amount she paid for the cake
Answer:
The total amount that Melissa paid for the cake is $82.5
Step-by-step explanation:
we know that
The total amount that Melissa paid for the cake is equal to the cost of the cake plus the sales tax
we have that
the cost is equal to $75
Find the sales tax
The sales tax is 10%, therefore find the 10% of the cost of the cake
10%=10/100=0.10
so
(0.10)*$75=$7.5
Adds the cost and the sales tax
$75+$7.5=$82.5
