Nancy has to find the reflection of a point across the x-axis. How can she find the new coordinates without graphing the point? Is there a rule that she can apply to find it?
Answer:To find the reflection of a point across the x-axis without graphing it, Nancy can change the sign of the y-coordinate and keep the sign of the x-coordinate the same.
Step-by-step explanation:
(x, y) transforms into (-x, y) is the rule that she can apply to find reflection.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given that Nancy has to find the reflection of a point across the x-axis
We need to find how can Nancy find the new coordinates without graphing the point
Let us find the rule that she can apply to find it
When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.
We do a reflection over the y-axis, then the value of y must be fixed.
Start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)
So the rule is, the y value remains equal and the x changes of sign.
(x, y) transforms into (-x, y)
Hence, (x, y) transforms into (-x, y) is the rule that she can apply to find reflection.

Answer:
3/16 miles/minute
Step-by-step explanation:
A rate of change describes how an output quantity changes relative to the change in the input quantity.
Points given:
Input Output
2 1/6
3 17/48
4 13/24
5 35/48
6 11/12
Here input values describe the time in minutes from 2 to 6 and output values describe the distance in miles from 1/6 to 11/12
Calculating the rate of change using the first two pairs of input-output values
Relative change = change in distance/change in time(17/48 - 1/6)/(3-2) = (17/48 - 8/48) /1 = 9/48 = 3/16 miles/minuteWe will get the same result if we take any other ordered pair of input and output values.

Right and solve an equation to find the number N
Six times the sum of a number and 15 is -42
Answer:
N=-22
Step-by-step explanation:
We first highlight all the information that is important and make an equation based on that. From that, we get 6(N+15)=-42. From there, we divide both sides by 6 to get N+15=-7. We subtract 15 from both sides to get N =-22, which is our answer.
Two times the sum of half a number and six is four. Find the number.
Answer:
The number is:

Hannah is asked to convert the number 0.00000305 to scientific notation. Her answer is 3.05 x 106.
Which statement best describes her answer?
Answer:
Hanna converted the number:
0.00000305
to:
3.05x10^6.
Now, when we have:
Ax10^n
This will "move" the value of A n times to the left, adding zeros when the decimals of A run over.
if we have
Ax10^-n
This will move A n times to the right.
Then the number:
3.05x10^6 = 3050000
This is clearly not the number that Hannah wanted to write.
The problem is that the exponent should be negative, if we have instead:
3.05x10^-6
We move our number 6 times to the right, adding zeros when necessary.
3.05x10^-6 = 0.00000305.
So Hannah is incorrect, she should wrote 0.00000305 = 3.05x10^-6
Answer: D. Hannah is not correct because the exponent should be -6.

The area of a rectangular wall of a barn is 216 square feet. Its length is 6 feet longer than twice its width. Find the length and width of the wall of the barn
Answer:
Length is 24 feet and width is 9 feet.
Step-by-step explanation:
It is given that length of a rectangular wall is 6 feet longer than twice its width.
Let x feet be the width of wall.
Length = 2x+6 feet
Area of rectangle is
[tex]A=length \times width[/tex]
[tex]A=(2x+6)\times x[/tex]
[tex]A=2x^2+6x[/tex]
It is given that area of a rectangular wall of a barn is 216 square feet.
[tex]2x^2+6x=216[/tex]
[tex]x^2+3x=108[/tex]
[tex]x^2+3x-108=0[/tex]
Splitting the middle term, we get
[tex]x^2+12x-9x-108=0[/tex]
[tex]x(x+12)-9(x+12)=0[/tex]
[tex](x+12)(x-9)[/tex]
[tex]x=-12,9[/tex]
Width can not be negative. So width is 9 feet.
Length [tex]=2(9)+6=18+6=24\text{ feet}[/tex]
Therefore, length is 24 feet and width is 9 feet.

What is the Value of X?
Answer:
x = 27
Step-by-step explanation:
4x+7 = 5(x-4)
4x + 7 = 5*x + 5*-4
4x + 7 = 5x - 20
7 + 20 = 5x - 4x
27 = x
Check:
4*27 + 7 = 5*(27-4)
108 + 7 = 5 * 23 = 115
Answer: x = 27
Step-by-step explanation:
These angles are congruent to each other so we well put an equal sign in between the two degrees.
Distribute the 5 by multiplying x and the -4 by 5 to get, 5x - 20
4x + 7 = 5x - 20
add 20 to the 7
subtract 4x from the 5x
27 = 1x

m=-1/4
Hope this help!
have a nice day!
Answer:
B
Step-by-step explanation:
So we have the equation:
[tex]\frac{3m-3}{5}=\frac{2m-1}{2}[/tex]
First, let's get rid of the fractions. Multiply both sides by the LCM of 5 and 2, which is 10:
[tex]10(\frac{3m-3}{5})=10(\frac{2m-1}{2})[/tex]
On the left, the 10 gets reduced to 2. On the right, the 10 gets reduced to 5. Thus:
[tex]2(3m-3)=5(2m-1)[/tex]
Distribute:
[tex]6m-6=10m-5[/tex]
Subtract 6m from both sides:
[tex]-6=4m-5[/tex]
Add 5 to both sides:
[tex]-1=4m[/tex]
Divide both sides by 4:
[tex]m=-\frac{1}{4}[/tex]
And we're done!
The answer is B.

Answer
[tex]5+2\sqrt{x} 13=12.211[/tex] or 5−2 this is where the square root would go 13=−2.211
Step-by-step explanation:
1.1 Factoring x2-10x-27
The first term is, x2 its coefficient is 1 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is -27
Step-1 : Multiply the coefficient of the first term by the constant 1 • -27 = -27
Step-2 : Find two factors of -27 whose sum equals the coefficient of the middle term, which is -10 .
-27 + 1 = -26
-9 + 3 = -6
-3 + 9 = 6
-1 + 27 = 26
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
2.1 Find the Vertex of y = x2-10x-27
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 5.0000
Plugging into the parabola formula 5.0000 for x we can calculate the y -coordinate :
y = 1.0 * 5.00 * 5.00 - 10.0 * 5.00 - 27.0
or y = -52.000
