What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever.
This refers to those as closed number lines. Number lines might be alternatively left empty or blank.
In the number line, negative numbers represent leftward distances. The product of a negative number and a positive number will be equal to the distance of the negative one by the number of times such distance is repeated.
The procedure is described as follows:
Draw the distance of the first negative number then Extend the distance by the magnitude of the second negative number.
And Draw the distance of the reflection of the result found in 2.

(c-d)/5 - 2 = 0
c-6d=0
Given the equations, what is the value of c/d?
PLZ HELP WILL MARK BRAINLIEST
Answer:
On the first equation, which is (c-d)/5 - 2 = 0 Let's start by solving c.
First, you need to add 1/5d to both sides:
1/5 c + -1/5 d - 2 + 1/5 d = 0 + 1/5 d
1/5 c - 2 = 1/5 d
Next, add 2 to both sides:
1/5 c - 2 + 2 = 1/5 d + 2
1/5 c = 1/5 d + 2
Now, divide both sides by 1/5:
1/5 c/ 1/5 = 1/5 d + 2/ 1/5
c = d + 10
so, therefore, your answer is c = d + 10
____________________________________________________________
Now we are going to do the 2nd equation, which is c-6d=0 Lets solve c.
The only thing you need to do is you need to add 6d to both sides:
c − 6d + 6d = 0 + 6d
c = 6d
So, therefore, your answer is c = 6d
Kwame must earn more than 16 1616 gold pieces per day to afford living in the City of Gold. Write an inequality that describes G GG, the number of gold pieces Kwame must earn per day to afford living in the City of Gold.
Answer:
G > 16
Step-by-step explanation:
The expression "more than" 16 gold pieces per day means that the number of gold pieces Kwame earns each day (G) must be greater than 16. In order to represent that as an inequality, we should use the greater-than sign: >.
The inequality that describes the number of gold pieces Kwame must earn per day is G > 16.

Hyperbola Question:
Two neighbors who live one mile apart hear an explosion while they are talking on the telephone. One neighbor hears the explosion two seconds before the other. If sound travels at 1100 feet
per second, determine the equation of the hyperbola on which the explosion was located.
(i know the answer is
[tex] \frac{ {x}^{2} }{1210000} - \frac{y {}^{2} }{5759600} = 1[/tex]
but i don't understand how you get it)
Answer:
[tex]\dfrac{x^{2}}{1210000 } - \dfrac{y^{2}}{5759600} = 1[/tex]
Step-by-step explanation:
A hyperbola is a curve for which the difference of the distances |d₂ - d₁| of any point P from the foci is constant.
The definition leads to the equation
[tex]\dfrac{x^{2}}{a^{2}} - \dfrac{y^{2}}{b^{2}} = 1[/tex]
1. Calculate the value of a²
Assume the neighbours are at the foci A and B.
The explosion is farther from B than from A, so it occurred on the right branch of the hyperbola.
Then AB = 1 mi = 5280 ft
and the distance from the focus to the y-axis is
c = 2640
The vertices are (±a,0).
The speed of sound is 1100 ft/s, so B is 2200 ft further from the explosion.
The distance from A to the vertex V₁ is c - a. Then
AB = 2200 + 2(c - a) = 2200 -2(2640 - 2a) = 2200 +5280- 2a = 5280
2a = 2200
a = 1100
a² = 1 210 000
2. Calculate the value of b²
[tex]\begin{array}{rcl}a^{2} + b^{2} & = & c^{2}\\1100^{2} + b^{2} & = & 2640^{2}\\b^{2} & = & 2640^{2} - 1100^{2}\\& = & 6969600 - 1210000\\& = & \mathbf{5759600}\\\end{array}[/tex]
3. Write the equation for the hyperbola
[tex]\mathbf{\dfrac{x^{2}}{1210000 } - \dfrac{y^{2}}{5759600}} = \mathbf{1}[/tex]
The equation of the hyperbola is [tex]\frac{x^2}{1210000} -\frac{y^2}{5759600^2} = 1[/tex]
How to determine the equation of the hyperbolaThe equation of an hyperbola is represented as:
[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} = 1[/tex]
The given parameters are given as:
AB = 1 mile
a = 1100 feet
Express the distance AB as feet
AB = 5280 ft
So, the distance AB from the foci is:
[tex]c = \frac{AB}2[/tex]
This gives
[tex]c = \frac{5280}2[/tex]
[tex]c = 2640[/tex]
The value of b is calculated as:
[tex]a^2 + b^2 = c^2[/tex]
So, we have:
[tex]1100^2 + b^2 = 2640^2[/tex]
This gives
[tex]b^2 = 2640^2 -1100^2[/tex]
Evaluate
[tex]b^2 = 5759600[/tex]
Recall that:
[tex]\frac{x^2}{a^2} -\frac{y^2}{b^2} = 1[/tex]
So, we have:
[tex]\frac{x^2}{1100^2} -\frac{y^2}{5759600^2} = 1[/tex]
[tex]\frac{x^2}{1210000} -\frac{y^2}{5759600^2} = 1[/tex]
Hence, the equation of the hyperbola is [tex]\frac{x^2}{1210000} -\frac{y^2}{5759600^2} = 1[/tex]

how long will it take for ball to hit the ground with the equation h=-t^2+10t+22
Answer:
about 11.856 time units
Step-by-step explanation:
We have to assume the equation has something to do with the path of the ball relative to the ground. Perhaps it represents height, with t representing time. The height (h) will be zero for the values of t that satisfy ...
0 = -t^2 +10t +22
Using the quadratic formula, we can find the values of t that satisfy this equation:
t = (-10 ±√(10² -4(-1)(22)))/(2(-1)) = (-10 ±√188)/-2 = 5±√47
The value of h is zero for t ≈ 11.856.

Which inequality is shown in the graph?
Answer: D
Step-by-step explanation:
I don’t know how to explain this to you step by step but when it comes to questions like this try to think more “logically” (if that makes sense) especially if you’re not familiar with the topic, like me. Think about it, if it was the first one the line on the graph would be above the middle line (its addition plus its greater than y so that wouldn’t be correct). Now the second one is subtraction but its less than y and everything thats coloured goes up not down so it has to be greater than y. C is not the correct answer because its a regular equation and thats not what the question wants plus its the only question out of the the 4 answers which is completely the odd one out so you can just cancel that out. Mow we come to the last answer which is the correct answer because it follows all the right “points” I mentioned earlier. I hope this makes sense to you, sorry I couldn’t explain it better!

A population of 100 frogs has a growth rate of 1.25% each month. At this growth rate,
the function f(x) = 100(1.25)* gives the population in x months. In how many months
will the population first reach 500?
Answer: 7.2 months
Step-by-step explanation:
Hi, to answer this question we have to substitute f(x) =500 in the equation given:
f(x) = 100(1.25)^x
500= 100(1.25)^x
Solving for x (number of months)
500/100 = 1.25^x
5 = 1.25^x
log 5 =log 1.25^x
log 5 =x (log 1.25)
log 5 /log 1.25 =x
x = 7.2 months

At a zoo, youth tickets cost $5 and adult tickets cost $9. A group that purchased x youth tickets and y adult tickets spent $90 on tickets. What is the domain of the relationship
Answer:
0 ≤ x ≤ 18
Step-by-step explanation:
Let 'x' be the number of youth tickets purchased at the zoo and 'y' be the number of adult tickets purchased at the zoo.
At a zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. We can write as
5x + 9y = 90
to find x we divide both side by 5
x = (90-9y)/5 => 90/5 - 9y/5
x = 18 - 9y/5
The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is
0 ≤ x ≤ 18
At x = 0, it means only adult tickets were purchased.
At x = 18, it means only youth tickets were purchased.
Answer:
0 ≤ x ≤ 18

What is the value of X
Answer:
x=28
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
Therefore,
x+95+57=180
Add 95 and 57
x+152=180
We are trying to find x. In order to do this, we must get x by itself. 152 is being added to x. The opposite of addition is subtraction. So subtract 152 from both sides.
x+152-152=180-152
x=180-152
x=28
Let’s check our answer. Add all the angles together, to be sure they add to 180 degrees.
x+95+57=180
Substitute 28 for x
28+95+57=180
180=180
The equation above is true, so we know that x is equal to 28.
____________________________________
Hey!!
Solution:
X+95+57=180 (sum of angle in triangle)
or,X+152=180
or,X=180-152
X=28 degree.
The value of X is 28 degree.
