Alexa and Daniel , two students of middle school together collected $20 from the students for annual function of their school . Write a linear equation for this and draw a graph to depict the statement .
Answer:
x + y = 20
Step-by-step explanation:
Let the amount collected by Alexa = $x
& the amount collected by Daniel = $y
Total amount collected = $20
Therefore,
x + y = 20
what is 6/a-6 = 3/a-3 ?
help me please
Answer:
a=1
Step-by-step explanation:
Multiply all terms by a and cancel:
6+−6a=3+−3a
−6a+6=−3a+3(Simplify both sides of the equation)
−6a+6+3a=−3a+3+3a(Add 3a to both sides)
−3a+6=3
−3a+6−6=3−6(Subtract 6 from both sides)
−3a=−3
−3a
−3
=

(Divide both sides by -3)

Which statement could always be used to prove

2) 27 228
3) Z3 and Z6 are supplementary
4) Z1 and 25 are supplementary
Answer: D, m<5=55.1 and m<7=124.9
Step-by-step explanation: 5 is the opposite of 4 in this diagram becuase of the bisector so that would make it the same 55.1, while 7 is an obtuse angle so it's clearly more than 90°, leaving 124.9 the most logical explanation.
Statement, ∠3 and ∠6 are supplementary will always be used if lines AB and CD are parallel.
What is a traversal line?When a line passes through two lines on the same plane, is called traversal line.
Given that,
Two lines are AB and CD,
Also, a transversal line EF intersect line AB and CD.
According to traversal line property,
If two lines are parallel and a traversal line intersect two lines, then each pair of interior angles on the same side of the transversal is supplementary.
In the given figure, Angle 3 and 6 are interior angles
Implies that,
Angle 3 and angle 6 will be supplementary if line AB and CD are parallel.
Hence, statement ∠3 and ∠6 are supplementary shows that lines AB and CD are parallel.

Answer:
2,300
Step-by-step explanation:
since it turns it would be double and both radius would be 1,150ft you have to add them together and then you get 2,300ft.
The longest distance across the space the system still water is the diameter of the circle, that is 2300 feet and this can be determined by using the given data.
Given :
Brian orders a center pivot irrigation system to water his field system is made up of a line connected pipes that turn around a center point.Brian's system will be 1150 feet long.The following steps can be used in order to determine the longest distance across the space the system still water:
Step 1 - According to the given data, the Brian system will be 1150 feet long.
Step 2 - So, from the given data it can be concluded that the irrigation system moves about a point and form a circle whose radius is 1150 feet.
Step 3 - So, the longest distance across the space the system still water is the diameter of the circle, that is:

what is the equation of the line that passes through the point (4,7) and has a slope of o?
Answer:
The equation of the line that passes through the point (4,7) and has a slope of 0 will be:
[tex]y=7[/tex]Step-by-step explanation:
As we know the equation of a line in a slope-intercept form of an equation is
[tex]y = mx + b[/tex]
Here,
m is the slopb is the y-interceptso
substituting the point (4,7) and slope m=0
[tex]y = mx + b[/tex]
[tex]7=0(4)+b[/tex]
[tex]7=0+b[/tex]
[tex]b=7[/tex]
Therefore, the equation of the line that passes through the point (4,7) and has a slope of 0 will be:

There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club. Write a system of linear equations that represents this situation. Let x represent the number of students in the drama club and y represent the number of students in the yearbook club. How many students are in the drama club? The yearbook club?
Answer: There are 37 students in the drama club and 27 students in the drama club.
Step-by-step explanation:
Let x= number of students in the drama club.
y= number of students in the yearbook club.
As per given, we have
x+y=64
x=10+y
A system of linear equations that represents this situation:
x+y=64 (i)
x=10+y (ii)
Put value of x from (ii) in (i)
10+y+y=64
⇒ 2y= 54
⇒ y = 27 [Divide both sides by 2]
Put value of y in (ii) , we get
x= 10+27 = 37
Hence, there are 37 students in the drama club and 27 students in the drama club.

GivenEquation ax² + bx + c = 0One of the roots is twice the otherTo findShow that 2b² = 9acSolutionLet the roots be p and q
The sum and product of the roots:
p + q = -b/apq = c/aThe sum of the roots, considering p = 2q,
p + q = 2q + q = 3qAnd
3q = -b/a ⇒ q = -b/(3a)The product of the roots, considering p = 2q:
pq = 2q(q) = 2q²And
2q² = c/aSubstitute q with -b/(3a)
2(-b/(3a))² = c/a2b²/(9a²) = c/a2b² = 9a²(c/a)2b² = 9ac=================================================
17. .................................................
GivenQuadratic equation
ax² = bx + c = 0, with equal rootsTo findShow that b² = 4acSolutionEqual roots means the discriminant is zero:
D = √b² - 4ac√b² - 4ac = 0b² - 4ac = 0b² = 4ac3. Charlie needs to hire a plumber to fix his kitchen sink. ABC Plumbing charges a flat
fee of $50 plus 535 per hour, Pipes R Us charges a flat fee of $75 and $25 per hour.
How many hours will the two companies charge for the total cost to be equal?
Answer:
2 hoursStep-by-step explanation:
step one:
given
ABC Plumbing charges
flat fee=$50
charge per hour= $35------------------i want to assume you meant $35 and not $535
Pipes R Us charges
flat fee=$75
charge per hour= $25
Let the number of hours be x
the equation for the charges is given bellow
y=35x+50----------1
y=25x+75-----------2
equating 1 and 2
35x+50=25x+75
35x-25x=75-50
10x=20
divide both sides by 10
x=20/10
x=2 hours

what is the solution set of this inequality? 1<|x-2|<5
(-3, ) U ( , )
We first need to consider the absolute value of x-2 to find the solution set of this inequality, The solution set of this inequality is (3, 4, 5).
What is absolute value?An absolute value is a number's distance from 0 on the number line.
Since the inequality is 1<|x-2|<5, we can then determine the two extreme points of the absolute value of x-2.
These points are 1 and 5.
Now, to find the solution set of this inequality, we need to find the two points that are 1 and 5 units away from the point x = 2.
The two points that are 1 and 5 units away from x = 2 are 3 and 5 respectively.
This is because the absolute value of x-2 has two extreme points, which are 1 and 5 units away from the point x = 2.
Therefore, the two points that are 1 and 5 units away from x = 2 are 3 and 5 respectively.

The nth term of an AP is 12-4n. Find the first term and the common difference.
Answer:
the first term is 8 and common difference d is -4.
Step-by-step explanation:
We are given nth term of an arithmetic sequence is: aₙ=12-4n
We need to find first term and common difference of given arithmetic sequence
First term can be found by putting n=1:
[tex]a_n=12-4n\\a_1=12-4(1)\\a_1=12-4\\a_1=8[/tex]
So, first term is a₁= 8
Now to find common difference we need to find second term
Second term can be found by putting n=2
[tex]a_n=12-4n\\a_2=12-4(2)\\a_2=12-8\\a_2=4[/tex]
So, second term is: 4
The common difference is found by subtracting second term with first term: a₂-a₁= 4-8 = -4
So, first term is 8 and common difference d is -4
