Quadrilateral ABCD is the result of a reflection of quadrilateral EFGH over the line. Which line segment in the image corresponds to EH in the pre-image?
A.) AD
B.) AB
C.) BC
D.) CD
Answers
Answer: A) AD
Step-by-step explanation:
Given: Quadrilateral ABCD is the result of a reflection of quadrilateral EFGH over the line.
We know that after reflection each point on the pre-image has a corresponding point on its image that is equidistant from a given line of reflection.
Since, EH shows the first and the last character of the name .
Thus, the line segment in the image corresponds to EH in the pre-image is AD because A is the first and D is the last character of the pre-image.

The starting value is 13, this is given from x=0.
So the equation is y = 7x + 13, but that's not in the list.
We'll have to manipulate it until we find the formula that's equivalent. If we move the 13 to the left and the y to the right (the signs swap as you know), we get:
-13 = 7x - y
Swap the left and the right side and you get
7x - y = -13, that's answer D!

What is the discrimination of 3x^2+6x=2
Answers
D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
You must re-write 3x^2+6x=2 in standard form: 3x^2 + 6x - 2
Here a=3, b=6 and c= -2
The discriminant is b^2 - 4ac. Here, it's 6^2 - 4(3)(-2), or 36 + 24, or 60.
This quadratic has two real, unequal, zeros.

C. the number of miles Dee drove in h hours
D. the number of miles Dee had left to drive after driving h hours
Answers
60h represents the number of miles Dee drove each hr
** she was 705 miles from home....she drives 60 miles per hr....so each hr she drives, she is 60 miles closer to home
The statement that best represents the meaning of the term 60h is:
C. the number of miles Dee drove in h hours
Step-by-step explanation:The expression 705 – 60h gives the number of miles Dee is from home after driving h hours.
This means that initially he is: 705 miles away from the home.
Now, he is travelling at a speed of 60 miles per hour.
This means that the distance he travels in h hours is: 60h miles.

yasmine bought 6 gallons of apple juice. after filing up 4 bottles of the same juice, she had 0.3 gallons of apple juice left. What's the amount of apple juice in each bottle?
Answers
1.425 gallons/bottle
Further explanationGiven:
Yasmine bought 6 gallons of apple juice. After filling up 4 bottles of the same juice, she had 0.3 gallons of apple juice left.Question:
What is the amount of apple juice in each bottle?
The Process:
Let the amount of apple juice in each bottle as X.
The two steps for obtaining X are as follows:
Step-1: the total amount of apple juice is the initial gallon amount subtracted by the remaining gallon amount.
[tex]\boxed{ \ 6 \ gallons - 0.3 \ gallons = 5.7 \ gallons \ }[/tex]
Step-2: the total amount of apple juice divided by the number of bottles is the amount of apple juice in each bottle.
[tex]\boxed{ \ X = 5.7 \ gallons \div 4 \ bottles = \boxed{ \ 1.425 \ gallons/bottle \ } \ }[/tex]
Quick steps:
[tex]\boxed{ \ X = \frac{(6 - 0.3) \ gallons}{4 \ bottles} = \boxed{ \ 1.425 \ gallons/bottle \ } \ }[/tex]
Thus, the amount of apple juice in each bottle is 1.425 gallons.

The size of each bottle that is filled by apple juice is [tex]\boxed{\bf 1.425}[/tex].
Further explanation:
Given:
Yasmine bought [tex]6[/tex] gallons of apple juice.
She filled up [tex]4[/tex] bottles of same size.
She had [tex]0.3[/tex] gallon of apple juice left.
Calculation:
Consider the size of each bottle is [tex]x[/tex] gallons.
Total size of each bottle is [tex]4x[/tex] gallons.
Total amount of apple juice used in these [tex]4[/tex] gallons can be obtained by subtracting total amount of apple juice to remaining apple juice.
[tex]\boxed{6-0.3=5.7}[/tex]
Therefore, total size of the [tex]4[/tex] bottles is [tex]5.7\text{ gallon}[/tex].
Write the equation for the total size of the bottles.
[tex]\boxed{4x=5.7}[/tex]
Now find the value of [tex]x[/tex] which gives the size of the bottles.
[tex]\begin{aligned}4x&=5.7\\x&=\dfrac{5.7}{4}\\x&=1.425\end{aligned}[/tex]
Therefore, the size of each bottle that is filled by apple juice is [tex]\boxed{\bf 1.425}[/tex].
Simple method:
First find the total size of bottle and then divide by [tex]4[/tex].
The total size of each bottle can be obtained as follows:
[tex]6-0.3=5.7[/tex]
The size of each bottle can be obtained as follows:

Louise bought 114 pounds of roast beef at $2.00 per pound and 212 pounds of turkey at $1.50 per pound. What was her total cost? Enter your answer in the box. $
Answers
Answer: Hello there!
Louse bought 114 pounds of roast beef at $2.00 per pound, this means that each one of the 114 pounds cost $2, then the total cost of the roast beef is $2*114 = $228.
For the turkey she bought 212 pounds at a price of $1.50 per pound, with the same reasoning as before, we need to see $1.50*212 = $318
then she spend $228 in roast beef and $318 in turkey, then the total cost is the addition of this two: $228 + $318 = $546.

Answer: There is 211 number of acres of barley the farmer can plant and still be under budget.
hgfhfhfghfgh
Step-by-step explanation:
Since we have given that
Amount of budget = $18000
Expenses he spent to plant wheat = $8100
So, Total amount for acre is given by
[tex]\$18000-\$8100\\\\=\$9900[/tex]
Cost of each acre to plant = $47.00
So, the maximum number of acres of barley is given by

what is the solution to the system of equations ?
(-1,8)
(8,-1)
(5,1/2)
(1/2,5)
Answers
Answer: The solution of the system of the equation is, (8,-1)
Step-by-step explanation:
Using substitution method
[tex]2x+4y=12[/tex] .......... (1)
[tex]y=\frac{1}{4}x-3[/tex] ......... (2)
Now we are putting equation (2) into equation (1), we get the value of 'x'
[tex]2x+4(\frac{1}{4}x-3)=12[/tex]
[tex]2x+\frac{4}{4}x-4\times 3=12[/tex]
[tex]2x-x=12+12[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now put the value of 'x' in equation (2), we get the value of 'y'
[tex]y=\frac{1}{4}x-3[/tex]
[tex]y=\frac{1}{4}\times 8-3[/tex]
[tex]y=2-3[/tex]
[tex]y=-1[/tex]
Hence, the correct option is, (8,-1)
The solution to the system of equations is (-1, 8).
Explanation:The given system of equations is:
2x + 4y = 12
y = ⅓x - 3
To find the solution to the system, we can solve it by substitution or elimination method:
Substitution Method:
From the second equation, we have y = ⅓x - 3.Substitute this value of y in the first equation.Replace y with ⅓x - 3 in the first equation: 2x + 4(⅓x - 3) = 12.Distribute 4 to both terms inside the parentheses: 2x + ⅓*4x - 12 = 12.Combine like terms: 2x + ⅓*4x = 12 + 12.Combine like terms: 2x + ⅓*4x = 24.Simplify: 2x + 4/4*x = 24.Simplify: 2x + x = 24.Combine like terms: 3x = 24.Divide both sides by 3 to solve for x: x = 8.Substitute the value of x in the second equation to find y: y = ⅓(8) - 3 = 2 - 3 = -1.Therefore, the solution to the system of equations is (-1, 8).

WHAT IS THE RELATIONSHIP BETWEEN A DOMAIN, RELATION, AND RANGE??????
Answers
A function ff is a relation with a special property: for each a∈Aa∈A there is a unique b∈Bb∈B s.t. ⟨a,b⟩∈f⟨a,b⟩∈f.This unique bb is denoted as f(a)f(a) and the 'range' of function ff is the set {f(a)∣a∈A}⊆B{f(a)∣a∈A}⊆B.You could also use the notation {b∈B∣∃a∈A[⟨a,b⟩∈f]}{b∈B∣∃a∈A[⟨a,b⟩∈f]}Applying that on a relation RR it becomes {b∈B∣∃a∈A[⟨a,b⟩∈R]}{b∈B∣∃a∈A[⟨a,b⟩∈R]}That set can be labeled as the range of relation RR.
The relationship between a domain, relation, and range in mathematics is that the domain represents the set of input values, the relation shows the relationship between input and output values, and the range represents the set of output values.
Explanation:In mathematics, "a domain is the set of input values or independent variable in a relation or function". It represents the possible values for the input variable. A relation is a set of ordered pairs that shows the relationship between the input and output values. The range of a relation is the set of output values or dependent variable.
For example, let's consider a relation that relates the ages of students to their heights. The ages of the students would be the domain, the heights would be the range, and the ordered pairs would represent the relationship between age and height.
