Answer:
The solutions are (2,0) and (3,0)
Step-by-step explanation:
The common denominator is (x - 2)(x - 4) which comes to x^2 - 6x + 8 which is exactly what the denominator on the right hand side is.
2x (x - 4) - (x+3)(x - 2) = - 4x
============= ========
(x -2)(x - 4) x^2 - 6x - 8
Multiply both sides by x^2 -6x - 8
2x(x - 4) - (x^2 + x - 6 ) = - 4x Remove the brackets
2x^2 - 8x - x^2 - x + 6 = - 4x Combine like terms on the left
2x^2 - x^2 - 8x - x + 6 = - 4x
x^2 - 9x + 6 = - 4x Add 4x from both sides
x^2 - 9x + 4x + 6 = 0
x^2 - 5x + 6 = 0
This factors into
(x - 2) and (x - 3)
x - 2 = 0
x = 2
x - 3 = 0
x = 3

Is the point (0,4) a solution to the system
of inequalities below?
y<-3.x +4
y> 5x – 2
Answers
Answer:
No
Step-by-step explanation:
To determine if the point is a solution to either of the inequalities, substitute the variables with the point given. When y<-3.x+4 is substituted with (0,4), the inequality becomes 4<4, which proves that the point is inapplicable to the first inequality. Therefore, you do not need to continue to check its applicability with the second inequality.

====================================================
Explanation for problem 1
In line 1, I used the distributive rule a*(b+c) = a*b+a*c. On the left side the 3(n+2) becomes 3n+6. On the right side, the 9(6-n) becomes 54-9n
On the next line, I added 9n to both sides. The 3n on the left side updates to 3n+9n = 12n.
For the third line, I subtracted 6 from both sides. Then the last line involves dividing both sides by 12 to fully isolate n. To confirm the solution n = 4, plug it back into the original equation. You should get the same thing on both sides after simplifying.
------------------------------------
Explanation for problem 2
The steps here are similar as problem 1, but this time we're involving fractions. Unfortunately, these steps don't involve clearing out the fractions which is often a handy trick to use.
We use the distributive rule on line 1
For line 2, we subtract 2m/9 from both sides. Think of 2m/3 as 6m/9 to help combine the fractions. The denominators must be the same for you to be able to add or subtract fractions.
For line 3, we subtract 4/3 from both sides. Think of 4/3 as 12/9.
The last step is to multiply both sides by 9/4, which is the reciprocal of 4/9. Your teacher made a typo on the right hand side of the last line. It should read [tex]\frac{4}{9}m[/tex] and not [tex]\frac{2}{9}m[/tex]. Refer to the previous line.

Your answer:
Answers
Answer:
(6,21)
Step-by-step explanation:
Given that,
y = 2x + 9 .....(1)
y = 4x − 3 .....(2)
From equations (1) and (2),
2x + 9 = 4x − 3
Taking variables both sides and constants to another side.
9+3 = 4x-2x
12 = 2x
x = 6
Put the value of x in equation (1).
y = 2(6) + 9
y = 12 + 9
y = 21
The solution of the given equations is x = 6 and y = 21. If we graph them, they will intersect at (6,21).
Mr. Fox organizes a field trip to a museum. He orders 52 student tickets and 2 adult tickets. The cost of a student ticket is s and the cost of an adult ticket is a. The tickets Mr. Fox orders are for the students and teachers from 2 classes that he is taking to the museum. Each class pays for the same number of student tickets and each class pays for the same number of adult tickets. Write 52s + 2a as the product of the number of classes and the total cost per class. Use the number pad, a, and s to enter your answers in the boxes.
PLEASE DO NOT SEND ANY FAKE LINKS
thank you
Answers
Answer:
52·s + 2·a = [2] × ([26·s] + [a])
Step-by-step explanation:
The number of classes Mr. Fox takes to the museum = 2 classes
The number of tickets Mr. Fox orders = The number of students and teachers in the two classes
The number of students paid for by one of the classes = The number of students paid for by the other class
The number of adult paid for by one of the classes = The number of adult paid for by the other class
The expression for the total cost of the ticket is 52·s + 2·a
Let 'c' represent the total cost for each class
Therefore, given that each class pays for the same number of students and adults, we have;
2 × c = 52·s + 2·a
∴ c = (52·s + 2·a)/2 = 26·s + a
Therefore, given that we have 2 classes, we get;
52·s + 2·a = 2 × (26·s + a)

Carter paid $21 000 for a car and later sold it to Sienna for 75% of what he paid. Afterwards, Sienna sold it to her friend Charli for 60% of what she had paid Carter. How much did Charli pay for the car?
Answers
Answer:
Amount Charli paid for the car = $9,450
Step-by-step explanation:
Amount Carter paid for the car = $21,000
Sienna paid 75% of what Charli paid
Amount Sienna paid for the car = 75% of $21,000
= 75/100 * $21,000
= 0.75 * $21,000
= $15,750
Amount Sienna paid for the car = $15,750
Charli paid 60% of what Sienna paid
Amount Charli paid for the car = 60% of $15,750
= 60/100 * 15,750
= 0.60 * 15,750
= $9,450
Amount Charli paid for the car = $9,450
|x-1|-1=1 what’s the value of x
Answers
Answer:
x=3, x=-1
Step-by-step explanation:
|x-1|-1=1
Add 1 to each side
|x-1|-1+1=1+1
|x-1|=2
Now set the absolute value to ±2
x-1 = 2 and x-1 = -2
Add 1 to all sides
x-1+1 = 2+1 x-1+1 = -2+1
x=3 x = -1
Step-by-step explanation:
|x - 1| - 1 = 1
Add 1 to each side
|x - 1| - 1 + 1 = 1 + 1
|x - 1| = 2
Now set the value to +_ 2
x - 1 = 2 and x - 1 = -2
Add 1 to all sides
x - 1 + 1 = 2 + 1 x - 1 + 1 = -2 + 1
x = 3 x = -1

The second doughnut glazing machine can glare 78 dozen doughnuts in
2 hours
Based on this rate, what is the total number of hours it will take the second
machine tolar 135 doren doughnuts Show or explain how you got you
answer
Answers
Answer:
t = 3.46 hours, or 3 hours 28 minutes
Step-by-step explanation:
78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.
Donuts produced as a function of time: D(t), where t is the number of hours the macine runs.
Set D(t) = 135 dozen = (39 dozen/hr)t.
Solving this equation for t, we get:
t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes

Answers
Answer:
[tex]y=x[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axisy and x stay as they are while m and b are replaced with numerical values1) Determine the slope (m)
[tex]y=mx+b[/tex]
We're given that the slope of the line is 1. Plug this into the above equation
[tex]y=1x+b\\y=x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=x+b[/tex]
Plug in the given point (-7,-7)
[tex]-7=-7+b[/tex]
Add 7 to both sides to isolate b
[tex]-7+7=-7+b+7\\0=b[/tex]
Therefore, the y-intercept is 0. Plug this back into [tex]y=x+b[/tex]
[tex]y=x+0\\y=x[/tex]

A warehouse has a height of 8\frac{1}{2}8 2 1 meters, length of 120120 meters, and width of 20\frac{3}{10}20 10 3 meters
Answers
Answer:
10,353m³
Step-by-step explanation:
We can look for the volume of the warehouse since we are not told what to look for
Volume of the warehouse = length * width * height
Given
Length = 120m
Width = 20 3/10 = 203/20 m
Height = 8 1/2m = 17/2 m
Volume of the warehouse = 120 * 203/20 * 17/2
Volume of the warehouse = 6 * 203 * 17/2
Volume of the warehouse = 3 * 203 * 17
Volume of the warehouse = 10,353 cubic metres
Hence the volume of the warehouse is 10,353m³

required to pay off a promissory
note issued for $500.00 at 10%
ordinary interest and a 180-day
term?
Answers
Answer:
the total payment need to pay is $525
Step-by-step explanation:
Given that
The amount at promissory note issued is $500
The rate of interest is 10%
And, the time period is 180 days
So, the total payment included is
= $500 + ($500 × 10% × 180 days ÷ 360 days)
