The equation of line is y = ( 1/4 )x - 1 , where the slope is m = ( 1/4 ) and the graph is plotted
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = ( 1/4 )x - 1
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = 1/4
The y-intercept of the line is b = -1
The graph of the line y = ( 1/4 )x - 1 is plotted
Hence , the equation of line is y = ( 1/4 )x - 1

An employee took 5 vacation days bringing his new vacation day balance to 8 days.Which equation can be used to find, x, the number of vacation days the employee had before using 5 vacation days?
Answer:
[tex]x + 5 = 8[/tex]
Step-by-step explanation:
Given
[tex]Total = 8[/tex]
[tex]Additional\ Vacation = 5[/tex]
Required
Determine the equation to find initial days of vacation
This is represented with x.
To get a total of 8 days vacation, we must have the following expression.
[tex]Initial\ Days + Additional\ Days = Total[/tex]
Substitute values for initial days, additional days and total. So, we have
[tex]x + 5 = 8[/tex]
Hence, the required expression is: [tex]x + 5 = 8[/tex]

each gender?
1
(A) 32
(B) 0.031
1
(C) 16
5
(D) 16
(E) 4
Answer:
5/16
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Let's say r is the number of male puppies.
n = 5, r = 2, p = 0.5, and q = 0.5.
P = ₅C₂ (0.5)² (0.5)³
P = 5/16
The probability of getting two males and three females, assuming an even chance for each gender is [tex]\frac{5}{16}[/tex].
Given that,
In a litter of five puppies.There is two males and three females, assuming an even chance for each gender.Based on the above information, the calculation is as follows:
Here we use binomial probability:
[tex]P = ^nC_r p^r q^{n-r}[/tex]
Here n denotes the number of trials,
r denotes the number of successes,
p denotes the probability of success,
and q denotes the probability of failure (1−p).
Let's us assume the r be the number of male puppies.
Now
n = 5, r = 2, p = 0.5, and q = 0.5.
So, put the values
So,
[tex]P = ^5C_2 (0.5)^2 (0.5)^3[/tex]
= [tex]5 \div 16[/tex]
Therefore we can conclude that the probability of getting two males and three females, assuming an even chance for each gender is [tex]\frac{5}{16}[/tex].

Answer:
31.01, 180.8, 0.2, 15501
Step-by-step explanation:
Puzzle 1:
The first rule takes out 301
The second rule has to have a 1 in the units place so that takes out 3.1, 3.101, and 30.1
The 3rd rule takes out 1.01, and 1.03
Rule 4, is self explanatory, so it takes out 31.3
and the last rule takes out 31.1 bc there is no hundredths column
That leaves you with 31.01
Puzzle 2:
Rule 1 takes out 18180
Rule 2, self explanatory, takes out 180
Rule 3 takes out numbers less than 18 so 1.81 and 0.18
Rule 4 takes out 18.01, 1800, 188, and 18.8
That leaves you with 180.8
Puzzle 3:
Rule 1 takes out 0.24, 0.5, and 2.02
Rule 2 takes out 0.15
Rule 3 takes out 0.02, 0.01 and 0.1 (bc it just says greater than and not equal to so it takes this one out)
Rule 4 takes out 0.12
That leaves you with 0.2
Puzzle 4:
Rule 1 takes out 45000
Rule 2 takes out 5401, 5444, and 4544
Rule 3 takes out 5454
Rule 4 does not take out any because all the remaining numbers ( 14500, 15501, 14534, and 10500) have 5 hundreds
Rule 5 takes out 14500, 14534, and 10500
That leaves you with 15501

Jane worked for 10 hours on the weekend. She was paid $7.00 per hour. How much Medicare tax was withheld from her paycheck if the tax rate is 1.45%?
Answer:
The Medicare tax withheld from her paycheck if the tax rate is 1.45% was $1.015.
Step-by-step explanation:
First, you have to determine the amount that Jane earned by multiplying the amount she earns per hour for the number of hours she worked:
$7*10=$70
Then, you need to calculate 1.45% of $70:
$70*1.45%=$1.015
According to this, the answer is that the Medicare tax withheld from her paycheck if the tax rate is 1.45% was $1.015.

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
3x + y = 5
-2x - y = -10
Step 2: Solve for x
Elimination
Add 2 equations together: x = -5Step 3: Solve for y
Define original equation: 3x + y = 5Substitute in x: 3(-5) + y = 5Multiply: -15 + y = 5Add 15 on both sides: y = 20Step 4: Graph systems
Check the solution set and graph.
Answer:
x = -5
y = 20
Step-by-step explanation:
3x + y = 5 ⇒ y = 5 - 3x
-2x - y = -10 ⇒ 2x + y = 10
2x + (5 - 3x) = 10
5 - x = 10
x = -5
Substitution of x-value into "y = 5 - 3x":
y = 5 - 3(-5)
y = 5 + 15
y = 20
If an object is shot upward with an initial velocity, v0, in feet per second (ft/s), the velocity, v, in ft/s is given by the formula v=v0−32t, where t is time in seconds. Find the initial velocity of an object if the velocity after 2 seconds is 39ft/s.
Answer:
96m/s
Step-by-step explanation:
Given the velocity, v, in ft/s of an object given by the formula v=v0−32t,
Given
V = 39ft/s
t = 2secs
Required.
Initial velocity v0
Substitute the given parameters into the formula
v=v0−32t,
32 = v0-32(2)
v0 = 32+64
v0 = 96m/s
Hence the initial velocity of the object is 96m/s

Triangle EFG has an incenter and orthocenter of D. What kind of triangle is triangle EFG?
A. Right
В.
Isosceles
C. Scalene
D
Equilateral
Answer: D Equilateral
Step-by-step explanation: Center of a triangle is a point where lines intersect. There 4 most popular: centroid, circumcenter, orthocenter and incenter.
Altitude or Height of a triangle is a perpendicular line is draw from a vertex to the opposite side. There are 3 heights and they united (or intersect) at a point called Orthocenter
Incenter is a point where the three angle bisectors meet. Angle bisector is a line that divide the angles of the triangle in two equal angles.
Generally, each center is positioned at a different location on the triangle (in one example, the point is located outside the triangle).
However, there is a case in which incenter and orthocenter are coincidental. That case is for a equilateral triangle, a triangle whose angles and sides are the same.

Susan needs 228 ounces of fruit juice for a party. She is choosing between two brands of juice. Two Brands of Juice Brand A Brand B 12 ounces 8 ounces $2.55 $1.45 She finds the unit rate of each brand and rounds to the nearest cent. Which statement about the unit rates is true?
Answer:
Brand A costs approximately $0.21 per ounce
Brand B costs approximately $0.18 per ounce
Step-by-step explanation:
the rate can be regarded as the change in one entity with respect to the other
From the question, we know brand A
$ 2.55 for 12 ounces of juice, to Know the cost of single once of the juice is
($ 2.55/12ounce)
=$ 0.2125
But the conversation rate for dollar to cent is (1 dollar = 100 cents)
Then to convert $ 0.2125 to cent, we can say
1 dollar = 100 cents
$ 0.2125 =X cent , if we cross multiply we have
= 21.25 cents
Which is approximately 21 cents.
From the question, Brand B cost $ 1.45 for 8 ounces of juice.
to Know the cost of single once of the juice is ( $ 1.45/8 ounce)
=$ 0.18125
We can convert to cent like we did above
1 dollar = 100 cents
$ 0.18125 =X cents, if we cross multiply, we have
= 18.125 cents
which is approximately: 18 cents
Therefore, the true statement about the unit rate are"Brand A costs approximately $0.21 per ounce
Brand B costs approximately $0.18 per ounce"
