Answer:
m=7/9
Step-by-step explanation:
-5(-5m+5)=-2m-4
25m-25=-2m-4
25m+2m=-4+25
27m=21
÷ 27 ÷ 27 (divide both sides)
m=7/9 or .777 (infinite)

Does 2x +3 = 5 +2x have infinitely many solutions
Answer:
The equation 2x + 3 = x + x + 3 is an example of an equation that has an infinite number of solutions. Let's see what happens when we solve it. We first combine our like terms.
Step-by-step explanation:
pply the Distributive Property. 2. Combine like terms. 3. Add/subtract on both sides. 4. Multiply/divide on both sides. Note: You might not need to do all of these steps! Special Cases – 1. Infinitely many solutions - when solving your equation, you get results like. 0=0, 7=7 ... 3) 5(2x - 7) = 7x + 3x + 7. 4) 4x +2x - 2 = 6x -- 3 + 1

George is comparing two different phones. The screen of phone A has a width of 5.3 cm. The width of the screen on phone B is 5 and one-third cm. Which statement explains which phone has the wider screen?
The screens have the same width.
Screen A is wider, because 5.3 is greater than 5 and one-third..
Screen B is wider, because 5.3 is greater than 5 and one-third..
Screen B is wider, because 5 and one-third is greater than 5.3..
Answer:
the correct answer is that Screen B is wider, because 5 and one-third is greater than 5.3.
Step-by-step explanation:
E D G E N U I T Y 2020
The Screen B is wider, because 5 and one-third is greater than 5.3.
What is a decimal ?A decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point. The dot in a decimal number is called a decimal point. The digits following the decimal point show a value smaller than one.
According to the question
George is comparing two different phones.
Phone A : screen has a width of 5.3 cm
Phone B : The width of the screen is 5 and one-third cm.
i.e
The width of the screen of phone B = [tex]5\frac{1}{3}[/tex] cm
= [tex]\frac{16}{3}[/tex] cm
Converting it into decimal to compare
= 5.333 cm
Therefore ,
5.333 cm > 5.3 cm
i.e Phone B screen > Phone A screen
Hence, Screen B is wider, because 5 and one-third is greater than 5.3.

Rewrite as y−k=a(x−h)2 or x−h=a(y−k)2. Find the vertex, focus, and directrix.
y−3=(2−x)^2
Given:
The given equation is
[tex]y-3=(2-x)^2[/tex]
To find:
The vertex, focus, and directrix.
Solution:
The equation of a parabola is
[tex]y-k=a(x-h)^2[/tex] ...(i)
where, (h,k) is vertex, [tex]\left(h,k+\dfrac{1}{4a}\right)[/tex] and directrix is [tex]y=k-\dfrac{1}{4a}[/tex]
We have,
[tex]y-3=(2-x)^2[/tex]
It can be written as
[tex]y-3=(-(x-2))^2[/tex]
[tex]y-3=(x-2)^2[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]h=2,k=3,a=1[/tex]
Vertex of the parabola is (2,3).
[tex]Focus=\left(2,3+\dfrac{1}{4(1)}\right)[/tex]
[tex]Focus=\left(2,3+\dfrac{1}{4}\right)[/tex]
[tex]Focus=\left(2,\dfrac{13}{4}\right)[/tex]
Therefore, the focus of the parabola is [tex]\left(2,\dfrac{13}{4}\right)[/tex].
Directrix of the parabola is
[tex]y=3-\dfrac{1}{4(1)}[/tex]
[tex]y=3-\dfrac{1}{4}[/tex]
[tex]y=\dfrac{11}{4}[/tex]
Therefore, the directrix of the parabola is [tex]y=\dfrac{11}{4}[/tex].

Answer:
1)
Minimum is a 4th Degree
2)
Positive; Even
3)
[tex]x=-4, -1\text{ Odd Multiplicity}\\x=3\text{ Even Multiplicity}[/tex]
Step-by-step explanation:
Part 1)
The minimum degree of our function will be 4.
Looking at the graph, we know that the graph crosses the x-axis at -4 and -1. Since it crosses through the x-axis at these two points, these two factors must have an odd multiplicity.
So, it can be anything 1, 3, 5, 7, etc.
However, we will choose the lowest one, 1.
Next, we know that the graph bounces off at 3.
So, it must have an even multiplicity. In other words, 2, 4, 6, 8, etc.
We choose the lowest one, 2.
Therefore, the minimum degree of our function will be 1+1+2 or 4.
Part 2)
The degree of our polynomial is (and will always be) even. Therefore, both ends of the graph will go in the same direction.
Recall the simplest even polynomial, the parent quadratic function. When the leading coefficient is positive, both of the ends go straight up.
This applies to all polynomials with even degrees.
Therefore, since the arms of the graph is going straight up towards positive infinity, the leading coefficient of our graph must be positive.
Part 3)
This is similar to Part 1.
We can see that the graph touches the x-axis at -4, -3, and 1. So, the zeros of the function is: [tex]x=-4, -1, 3[/tex]
We know that it passes through [tex]x=-4 \text{ and } x=-1[/tex] . So, these two factors must have an odd multiplicity.
However, since the graph bounces off [tex]x=3[/tex], this factor must have an even multiplicity.
And we're done!

The height after t seconds of an object projected upward with an initial velocity of 48 feet per second from a 210-foot tower can be modeled by h=−16t^2 + 48t +210. The height of a neighboring 50-foot tall building is modeled by the equation h=50. The time (t) when the object will be at the same height as the building is found to be t = –2 and t =5. Which statement BEST describes the validity of these solutions?
A. Neither solution is valid since time values cannot be squared.
B. The solution t = – 2 is the only solution since 5 seconds is an unreasonable amount of time for the object to reach a height of 50 feet.
C. The solution t = 5 is the only valid solution to this system since time cannot be negative.
D. Both are valid solutions to this system since both values make the equation h=−16t^2 + 48t + 210 true.
Answer:
C. The solution t = 5 is the only valid solution to this system since time cannot be negative.
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 48t + 210[/tex]
[tex]h(t) = 50[/tex]
Required
Determine which of the options is true
After solving
[tex]h(t) = -16t^2 + 48t + 210[/tex]
for
[tex]h(t) = 50[/tex]
We have that
[tex]t = -2[/tex] and [tex]t = 5[/tex]
Because time can't be negative, we have to eliminate [tex]t = -2[/tex]
So, we're left with
[tex]t = 5[/tex]
Because of this singular reason, we can conclude that option c answers the question

O rotation of 90° counterclockwise about the origin, followed by a translation (x, y) = (x + 2 y + 1).
reflection over the line y = x, followed by a translation (x, y) + (x + 1, y + 1).
O rotation of 180° about the origin, followed by a translation (x, y) - (x + 1, y + 1).
o translation (x,y) → (x + 1, y + 1), followed by a rotation of 180°counterclockwise about the origin.
Answer:
rotation of 180° about the origin, followed by a translation (x, y) - (x + 1, y + 1).
Step-by-step explanation:
Remember that a rotation of 180º about the origin will result in the change of both X's and Y's signs to the opposite so if the sign of one of them is negative, it will be positive, and viceversa.
Since point R is (-2,4) the first transformation would change the signs and make it (2,-4) the next one would be transform it by adding 1 to both of them:
(x,y)---(x+1,y+1)
(x,y)---(2+3,-4+1)
(x,y)---(3,-3)
So that would be the correct answer.
Answer:
Rotation of 180° about the origin, followed by a translation (x, y) - (x + 1, y + 1).

Standard deviation is a useful concept in performance management. Let us say that a director in a local fire department wants to know any variation between the performance of this year and that of the last year. He draws a sample of 10 response times of this year ( in minutes):
3.0, 12.0, 7.0, 4.0, 4.0, 6.0, 3.0, 9.0, 11.0, and 15.0, comparing them with a sample of 10 response times last year ( in minutes): 8.0, 7.0, 8.0, 6.0, 6.0, 9.0, 7.0, 9.0, 8.0, and 6.0.
Required:
a. Does he see a performance variation by the mean?
b. Does he see a performance variation by the standard deviation? If he does, is it performance improvement or deterioration from the last year? Why?
Answer:
Step-by-step explanation:
Given the data :
Response time this year :
3.0, 12.0, 7.0, 4.0, 4.0, 6.0, 3.0, 9.0, 11.0, 15.0
Response time last year :
8.0, 7.0, 8.0, 6.0, 6.0, 9.0, 7.0, 9.0, 8.0, 6.0
Let's calculate the mean and standard deviation of each data sample :
Mean(m) = Σ(X) / n
n = sample size = 4
This year:
ΣX = 74 ; n = 10
Mean = 74 /10 = 7. 4
Standard deviation(s) = √(Σ(x - m)²/n - 1)
s = 4.195
Using a calculator to save computation time :Standard deviation = 4.195
LAST YEAR :
ΣX = 74 ; n = 10
Mean = 74 /10 = 7. 4
Standard deviation(s) = √(Σ(x - m)²/n - 1)
Using a calculator to save computation time :Standard deviation = 1.17
a. Does he see a performance variation by the mean?
From the mean value obtained for the two years, both are the same, hence, the value does not signify a variation in performance.
b. Does he see a performance variation by the standard deviation? If he does, is it performance improvement or deterioration from the last year? Why?
Yes, the value of standard deviation are different with the current year having a value of 4.195 and the previous year, a value of 1.17
The variation shows there is a deterioration on this year's performance from last year due to the larger value of standard deviation obtained ; 4.195 > 1.17
