Graph the solution set.-10x≤2y
Answers
To be able to determine the graph of this inequality, we'll start rearranging the inequality putting the "y" variable at the left side of the equation.
[tex]\begin{gathered} -10x\leq2y \\ \frac{-10x}{2}\leq\frac{2y}{2} \\ -5x\leq y \\ or \\ y\ge-5x \end{gathered}[/tex]Since the inequality here is greater than or equal to, this means that the shade is above the solid line.
This equation also has a slope of -5 and y-intercept of 0.
Therefore, the graph of this equation looks like this:

is the median of a data set is the same whether you order the set from greatest to least or least to greatest?
Answers
The value of median will be same.
Given:
The objective is to determine whether the median of a data set is same or not while ordering from greatest to least or least to greatest.
There are two possible data sets, which is even number of sets or odd number of sets.
If the number of sets (n) is even, consider two terms,
[tex]\frac{n}{2}\text{ and }\frac{n+1}{2}[/tex]Then, the average of these two numbers will gives the median of the even sets.
If the number of sets (n) is odd, the median can be calculated as,
[tex]\frac{n}{2}[/tex]Hence, the value of median will be same, even if the order of the sets are arranged greatest to least or least to greatest.
Nicole runs 7 miles in 60 minutes. At the same rate, how many miles would she run in 24 minutes?
Answers
In 24 minutes, Nicole runs the distance of 2.8 miles.
What is miles?
In mathematics, The term 'miles' is a unit of distance. It is used for the calculation of displacement measurement. It is defined as the starting point and endpoints on the graph.
According to the question, Nicole runs 7 miles in 60 minutes. Therefore, the parameters are:
Distance = 7 miles; Time = 60 minutes
Therefore, Speed = Distance/Time = 7/60 miles/minutes
Now, the time is 24 minutes and speed is 7/60 miles/minutes.
The required distance can be calculated as:
Distance = (Speed)(Time) = (7x24/60) = 28/10 = 2.8 miles
Hence, In 24 minutes, Nicole runs 2.8 miles.

dilate the figure about the given point a scale factor of 2.
Answers
1) The first thing to dilate a figure, is to know the scale factor and if it's about the origin or not.
We have k=2, as our scale factor. So the image will be twice larger (scaled) than the pre-image.
2) Since it is not about the origin but about the point, We need to count from the center of dilation (that point).
2.1) Let's locate each point of the vertex, and call them by ABCD for that pre-image, and call E the point which is going to be the center of dilation.
Counting the distances from figure ABCD to point E

Answers
Using the mathematical operations, the quantity that each of the six friends got from the 3/8 of pizza remaining after 4 hours is 0.75.
What are the mathematical operations?The mathematical operations that are used to perform basic number operations are division, multiplication, subtraction, and addition.
These basic mathematical operations can be used to compute the quantity of pizza that each friend got from the remainder.
For instance, after determining that 4.5 of the pizza is remaining, this value can be shared by 6 to get 3/4 or 0.75 for each friend.
The number of friends in the group = 6
The number of equal pieces of pizza = 12
The quantity of pizza remaining after 4 hours = 3/8 or 4.5 (12 x 3/8)
The quantity received by each friend after the equal splitting of the remainder = 0.75 (4.5/6) or 3/4 (3/8 ÷ 6).
Thus, basic mathematical operations show that each friend will get 3/4 more pizza.

Given that,
The table is a proportional relationship.
Workout hours are 1 2 3
Calories Burned are 240 480 720
We can conclude from the form of the question that the quantity of calories we burn is determined by the length of time we spend practicing, making the activity (hours) the independent variable and the calories burned the dependent one. The responses C and D are automatically canceled out by this.
The table's information is all we can then depend on. The assigned hours were 1, 2, and 3, and the corresponding calories were 240, 480, and 720. Just make sure that's reflected in the response.

using this module predict when it will take to reach approximately 300 female turtles ? how many female turtles will there be in 7 years?
Answers
Answer
a) It will take 3.54 years for the turtle population to hit 300 female turtles.
b) There will be 78,125 female turtles in 7 years.
Explanation
The model has been give to us as
T(t) = 5ᵗ
where
T(t) = Female turtle population at any time t
t = time in years
First part of the question asks us to find when the turtle population will hit 300 female turtles. That is, find t when T(t) = 300
T(t) = 5ᵗ
300 = 5ᵗ
We can rewrite this as
5ᵗ = 300
We will take the natural logarithms of both sides
In 5ᵗ = In 300
t (In 5) = In 300
t (1.6094) = 5.7038
Divide both sides by 1.6094
t = (5.7038/1.6094)
t = 3.54 years = 3 years, 6.5 months
For the second part of the question, we want to calculate the number of female turtles when t = 7 years
T(t) = 5ᵗ
T(7) = 5⁷ = 78,125 female turtles

June, she found that she could only buy 3/5
a bag for N2400. What was the percentage
increase in price from April to June
Answers
The percentage increase in price from April to June to Mrs Ezeaku, based on the cost of the bag is 66.7%
How to find the percentage increase?First, find the price of a bag in June. If 3/5 of a bag costs N2,400, then a full bag would be:
= Cost of proportion / Proportion of bag
= 2, 400 / (3 / 5)
= N4, 000
The percentage increase from April to June is:
= ( Price in June - Price in April) / Price in April x 100%
= ( 4, 000 - 2, 400) / 2, 400 x 100%
= 1, 600 / 2, 400 x 100%

X^2+y-9=0 test for symmetry
Answers
We have three tests of symmetry. In respect to the y-axis or in respect to the x-axis, or in respect to the origin.
For symmetry with respect to the Y-Axis, check to see if the equation is the same when we replace x with −x:
[tex]x^2+y-9=(-x)^2+y-9=0[/tex]Since the equation remains the same when we change the sign of the x variable, the equation is symmetric in respect to the y-axis.
For symmetry with respect to the X-Axis, check to see if the equation is the same when we replace y with −y:
[tex]x^2+y-9\ne x^2+(-y)-9=x^2-y-9[/tex]Since the equation does not remains the same when we change the sign of the y variable, the equation is not symmetric in respect to the x-axis.
The equation is symmetric with respect to the origin if for every point (x,y) that satisfies the equation, the point (-x, -y) also satisfies the equation.
[tex](-x)^2+(-y)-9=x^2-y-9\ne x^2+y-9[/tex]Since it doesn't satisfies this condition, the equation is not symmetric with respect to the origin.

The vertical asymptote of a function is the x value gotten when the denominator is equated to 0.
The denominator of the function given can be equated to 0 as shown below:

The dosage of a cold medication is 2 mg for every 80 lb of body weight. How many milligrams of this medication are required for a person who weighs 140 lb? mg
Answers
Let x represent the amount of milligrams required for a person who weighs 140 lb.
We were told that the dosage of a cold medication is 2 mg for every 80 lb of body weight. The equations would be set up as shown below
2 = 80
x = 140
By crossmultiplying, we have
x * 80 = 2 * 140
80x = 280
We would divide both sides of th equation by 80. We have
80x/80 = 280/80
x = 3.5
Therefore, 3.5 milligrams of this medication are required for a person who weighs 140 lb
