Step-by-step explanation:
this relation is not a function cuz each x pair (domian) has only one image in y pair (codomain) so we will have all the ×-axis pairs meeting with y-axis in only one point as they have one image as this is the rule of having a function so what in front of us the positive part of x-axis has two images in y-axis
u can knew it by another way draw a vertical line and if it meets in two point or more than one then the relation is not a function s o if we draw a vertical line in the right part of the graph it will meats in two points then not a function
the domain is all the pairs of this relation taken in x-axis which are [0,infinity[ and range is the y-axis images if the fomain in x-axis which are ]-infinity, infinity[

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) in the same proportion, the rule of three applies as follows:
a ⇒ b
c ⇒ x
Then: [tex]x=\frac{c*b}{a}[/tex]
where a, b and c are known values and x is the value to be calculated.
In this case, the rule of three applies as follows: if 1/20 of a ton is the weight of 1 person, 3/4 of a ton is the weight of how many people?
[tex]number of people =\frac{\frac{3}{4} of a ton*1 person }{\frac{1}{20} of a ton}[/tex]
or, what is the same,
number of people* [tex]\frac{1}{20}[/tex] = [tex]\frac{3}{4}[/tex]
Solving:
number of people= 15

Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe any patterns. Number of classes: 8 Data set: Finishing times (in seconds) of 20 male participants in a 5K race
Answers
Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382

7. A recipe for 12 people needs the following ingredients. Brian is going to adjust the recipe
for 3 people.
4 whole eggs
4 1/4cups of sugar
7 cups of flour
41/2cups of milk.
Part A
How much flour will Brian need if he is making it for 3 people?
Part B
How much sugar will be needed if he is making it for 3 people?
Answers
Answer:
A. Brian will need 1.75 (1 3/4) cups of flour
B. Brian will need 1 1/16 cups of sugar
Step-by-step explanation:
Brian wants to make it for 3 people, so everything must be divided by 4 since 12/4=3.
7/4=1.75
4 1/4 divided by 4=1 1/16
Answer:A is 21 cups of flour and B is 12 3/4 cups of sugar
Step-by-step explanation:
A is 21 because 7x3 is 21 and B because 4 1/4x3 equals 12 and 3/4 cups
Solve the equation

Write it step by step. I really need help
Answers
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2(2x−4)=4x
(−2)(2x)+(−2)(−4)=4x(Distribute)
−4x+8=4x
Step 2: Subtract 4x from both sides.
−4x+8−4x=4x−4x
−8x+8=0
Step 3: Subtract 8 from both sides.
−8x+8−8=0−8
−8x=−8
Step 4: Divide both sides by -8.

find the zero of the function h(x) = 4x+2
Answers
Answer:
[tex]x=-1/2=-0.5[/tex]
Step-by-step explanation:
So we have the function:
[tex]h(x)=4x+2[/tex]
To find the zero(s) of a function, set the function equal to 0 and solve for x. So:
[tex]0=4x+2[/tex]
Subtract 2 from both sides:
[tex]-2=4x[/tex]
Divide both sides by 4:
[tex]x=-1/2=-0.5[/tex]
So, the zero of the function is -0.5.
This means that the graph (a line) crosses the x-axis at (-0.5, 0).

Answers
Answer:
They are 260 miles apart. No it would not be possible.
Step-by-step explanation:
If they are 260 miles apart and you drive at a constant speed on 70mph. You will have to 260/70 which = 3.7 or 4 so it would not be possible.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
It is not possible to make this trip in [tex]3[/tex] hours.
By using any geographical tool, such as the local map or you can use internet too to find the distance between Amarillo and Oklahoma City.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Time = \frac{Distance}{Speed}[/tex]
[tex]Time = \frac{260}{70}[/tex]

The actual distance between the library and train station is 500 ft. Explain how you
could find the distance between them in centimeters on the map.
Answers
Answer:
15,420 cm
Step-by-step explanation:
Given the actual distance between the library and train station to be 500 ft, to find the distance between them in centimeters, we ill convert 500 ft to cm as shown;
Given the conversion:
1 ft = 30.48cm
500ft = x cm
Cross multiply
x cm * 1ft= 30.48 cm * 500ft
x cm = 30.48 cm * 500ft/1ft
x cm = 15,240 cm
Hence the distance between them in centimeters on the map is 15,420 cm

The price of 2 tons of gravel is $128.
Given:
The price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.
To find:
The price of 2 tons of gravel.
Explanation:
Let [tex]x[/tex] be the price of 1 ton of gravel.
Then the price of [tex]\dfrac{3}{8}[/tex] ton is [tex]\dfrac{3}{8}x[/tex] and the price of 2 tons of gravel is [tex]2x[/tex].
It is given that the price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.
[tex]\dfrac{3}{8}x=24[/tex]
[tex]x=\dfrac{8}{3}\times 24[/tex]
[tex]x=8\times 8[/tex]
[tex]x=64[/tex]
Now, the price of 2 tons of gravel is:
[tex]2x=2(64)[/tex]
[tex]2x=128[/tex]
Therefore, the price of 2 tons of gravel is $128.

First you would round 0.092, which would just be 0.09 because 2 is less than 5. You would then have 9.49. You would then round the 0.49, and since 9 is greater than 5, it would be 9.5 because 9 would round to 10.

Answers
Answer:
-2
Step-by-step explanation:
Here is a number line:
<-------+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+------>
-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
Start at 3, marked with an S below:
<-------+-----+-----+-----+-----+-----+-----+-----+-----+-----S----+-----+-----+------>
-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
Since you are adding a negative number, -5, count 5 numbers to the left starting on P which corresponds to 3.
5<---4<---3<----2<---1<---Start
<-------+-----+-----+-----+-----E-----+-----+-----+-----+-----S----+-----+-----+------>
-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6
You end up at E which corresponds to -2.
Therefore, -5 added to 3 is -2.
