The solution set to the inequality, -1/2m ≥ 7/11, is: m ≤ -14/11.

See attachment for the graph.

If the possible set of values to an inequality is "greater than or equal to" (≥), or "less than or equal to" (≤), then a closed circle is used to indicate the point on the graph.

On the other hand, an open circle is used for "< or >".

If it is "> or ≥" the shaded arrow is drawn to the right, if "< or ≤", it is drawn to the left of the inequality graph.

Given the inequality, -1/2m ≥ 7/11, solve for m:

-1/2m(-2) ≥ 7/11(-2)

m ≤ -14/11 [the sign changes because we are multiplying both sides by negative number]

The solution to the inequality is: m ≤ -14/11.

The graph is given below for m ≤ -14/11.

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

2([tex]\frac{2}{5}[/tex] ) + 2(- [tex]\frac{1}{5}[/tex] )

= [tex]\frac{4}{5}[/tex] + (- [tex]\frac{2}{5}[/tex] )

= [tex]\frac{4}{5}[/tex] - [tex]\frac{2}{5}[/tex]

= [tex]\frac{2}{5}[/tex]

Answer: C

Step-by-step explanation:

Starting off we need to understand what the circles are in inequalities.

A closed circle means that the number on the inequality is included in the solution. An open circle means that the number in the inequality is not included in the solution. A closed circle would use [tex]\leq or \geq[/tex]. An open circle would use < or >.

So, using these processes, -2<x[tex]\leq[/tex]7 would be the answer.

Due to the fact that the line does not pass through the origin, the equation does not represent a proportionate relationship.

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.

Given Data

The remaining length (L) of 120-inch rope after x inches have been cut off: 120- x = L.

The fact that

If a relationship between two variables, x and y, can be written as or, then it represents a proportionate variation.

y = kx

The line passes through the origin, and the constant of proportionality, k, is equal to the slope of the line, m.

There are

The length (L) of a 120-inch rope that is left after x inches have been removed.

There are

The dependent variable is L —->. (output variable)

The independent variable is x. (input variable)

The linear formula is

L = 120-x

The original price of the motorcycle is approximately $7,987.

Here, we are given that p represent the motorcycle’s original price.

The sale price of Dealer A will be-

7.5% less that the original price

= 92.5% of p

= 0.925p

Similarly, the sale price of dealer B will be-

$599 less than original price

= (p - 599)

Now, these two prices are equal, so we can equate the two-

0.925p = (p - 599)

0.925p = p - 599

0.925p - p = -599

-0.075p = -599

p = -599/-0.075

p = 599/0.075

p = 599000/75

p = 7,986.67

Thus, the original price of the motorcycle comes out to be approximately $7,987.

Suppose a life insurance company sells a $280,000 one year term life insurance policy to a 24 year old female for $290.Then The expected value of this policy to the insurance company is $168.76

Probability that Person doesn't die = 0.999567. Profit = Revenue - Cost; Profit = $290 - 0 = $290

Probability that Person dies = 1 - 0.999567 = 0.000433. Profit = Revenue - Cost; Profit = $290 - $280000 = -$279710

Expected Value E(X) = ∑xp(x)

E(X) = $290*(0.999567) + (-$279,710* 0.000433)

E(X) = $289.87443 - $121.11443

And the solution is x = 18.

Here we have the following mathematical sentence:

"three is a number divided by 6"

If we define x as the "number", then we can write this as:

3 = x/6

So we have a simple linear equation, to solve this, we just need to multiply both sides of the equation by 6, we will get:

3*6 = (x/6)*6

18 = x

Step-by-step explanation:

The interval where the product will at least break even is [tex]$\left[\begin{array}{cc}\text { Solution: } & x \leq-5 \\ \text { Interval Notation: } & (-\infty,-5]\end{array}\right]$[/tex]

Given C= 305 x+1350C

R=60 x

To find the interval where the product will at least break even we must have [tex]$R(x) \geq c(x)$[/tex]

[tex]$\Rightarrow \quad 35 x \geq 305 x+1350$[/tex]

[tex]$$35 x \geq 305 x+1350$$[/tex]

Subtract 305 x from both sides

[tex]$$35 x-305 x \geq 305 x+1350-305 x$$[/tex]

Simplify

[tex]$$-270 x \geq 1350$$[/tex]

Multiply both sides by - 1 (reverse the inequality)

[tex]$$(-270 x)(-1) \leq 1350(-1)$$[/tex]

Simplify

[tex]$$270 x \leq-1350$$[/tex]

Divide both sides by 270

6 x 2 = 12

The sum of the  partial products is,

16 x 52 = 500 + 300 + 20 + 12 = 832

Here the partial products method is used to find the product of two two digit numbers 16 and 52.

For this a table of the form given in the figure is constructed in which the partial products are found.

For this first split 16 and 52 into 10 + 6 = 16 and 50 + 2 = 52.

Then take the partial products between 10 and 50, 10 and 2, 6 and 50, 6 and 2. Then take the sum of all these four values to get the final answer. This is the method of partial products.

So finding the partial products,

10 x 50 = 500

10 x 2 = 20

6 x 50 = 300

6 x 2 = 12

To find the final answer, take the sum of these products.

The Zero Product Property simply notes that if ab = 0, then either a = 0 or b = 0. The solutions exists x = -4, x = -2, x = 1.

The zero-product property in algebra asserts that two nonzero items cannot be multiplied together to produce zero.

The Zero Product Property simply notes that if ab = 0, then either a = 0 or b = 0 (or both). A product of factors exists zero if and only if one or more of the factors exists zero.

Let the given equation be (x+4)(x+2)(x-1)=0

By using the Zero Factor Principle, we get

If ab = 0 then a = 0 or b = 0

then x + 4 = 0 or x + 2 = 0 or x - 1 = 0

Solve x + 4 = 0

⇒ x = -4

Solve x + 2 = 0

⇒ x = -2

Solve x - 1 = 0

⇒ x = 1

The solutions are x = -4, x = -2, x = 1

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. A common, vulgar, or simple fraction is one that has a non-zero denominator shown below (or after) the line that separates the numerator from the denominator. Composite fractions, complicated fractions, and combined numeral fractions are examples of uncommon fractions that use numerators and denominators.

Composite functions are when the output of one function is used as the input of another.

Therefore, the given composite function (f o g)(x) means to substitute function g(x) in place of the x in function f(x).

[tex]\begin{aligned}(f \circ g)(x) & = x^2\\f(g(x)) & = x^2\\\implies 3(g(x))-1 & = x^2\\3(g(x))-1+1 & = x^2+1\\3(g(x))&=x^2+1\\\dfrac{3(g(x))}{3}&=\dfrac{x^2+1}{3}\\\implies g(x)&=\dfrac{x^2+1}{3}\end{aligned}[/tex]
