Graph Jkl and its image after a reflection in the given line J(5,3), K(1,-2), l(-3,4); y-axis
When a shape is reflected, it must be reflected across a line.
See attachment for the graphs of JKL and the image of JKL
The coordinates of JKL are given as:
[tex]J = (5,3)[/tex]
[tex]K = (1,-2)[/tex]
[tex]L = (-3,4)[/tex]
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex]J' =(-5,3)[/tex]
[tex]K' =(-1,-2)[/tex]
[tex]L' = (3,4)[/tex]

What is the solution to the compound inequality in interval notation? 2(x+3)>6 or 2x+3≤−7
Answer: The required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]
Step-by-step explanation: We are given to find the solution to the following compound inequality in interval notation :
[tex]2(x+3)>6~or~2x+3\leq -7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To find the solution to (i), we must solve both the parts separately.
The inequality (i) can be solved as follows :
[tex]2(x+3)>6\\\\\Rightarrow x+3>\dfrac{6}{2}\\\\\Rightarrow x+3>3\\\\\Rightarrow x>3-3\\\\\Rightarrow x>0\\\\\Rightarrow x\epsilon (0,\infty)[/tex]
or
[tex]2x+3\leq-7\\\\\Rightarrow 2x\leq-7-3\\\\\Rightarrow 2x\leq -10\\\\\Rightarrow x\leq -\dfrac{10}{2}\\\\\Rightarrow x\leq-5\\\\\Rightarrow x\epsilon(-\infty,-5].[/tex]
Thus, the required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]

Mr. Plum's math class of 25 students had an average of 85 on a test. Miss Scarlett's class of 22 students had an average of 87 on the same test. What is the average of the two classes combined?
A mean is an arithmetic average of a set of observations. The average of the two classes combined is 85.936.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
Mr. Plum's math class of 25 students had an average of 85 on a test.
Average = Total marks /Total number of students
Total marks of Mr. Plum's class = Total number of students × Average
Total marks of Mr. Plum's class = 25 × 85
Total marks of Mr. Plum's class = 2,125
Miss Scarlett's class of 22 students had an average of 87 on a test.
Average = Total marks /Total number of students
Total marks of Miss Scarlett's class = Total number of students × Average
Total marks of Miss Scarlett's class = 22 × 87
Total marks of Miss Scarlett's class = 1,914
Further, the average of the two classes combined is,
Average = Total marks / Total students
= (2,125 + 1914)/(25+22)
= 4039/47
= 85.936
Hence, the average of the two classes combined is 85.936.

Amy is eight years older than twice her cousin Alicia’s age. The sum of their ages is less than 32. Let x represent Alicia's age. Which inequality represents Alicia’s possible age?
To find Alicia's possible age, we can write an inequality based on the given information, solve it, and express Alicia's age in terms of a variable.
Explanation:To find the inequality that represents Alicia's possible age, we can start by representing Amy's age in terms of Alicia's age. Let x represent Alicia's age. Amy is eight years older than twice Alicia's age, so Amy's age is 2x + 8. The sum of their ages is less than 32, so we can write the inequality x + (2x + 8) < 32 to represent their ages. Simplifying the inequality gives us 3x + 8 < 32. We can now solve for x by subtracting 8 from both sides of the inequality: 3x < 24. Divide both sides of the inequality by 3 to isolate x: x < 8. Therefore, Alicia's possible age is less than 8, and the inequality that represents her age is x < 8.

Factor the expression. k2 + kf – 2f2
Answer:
Factorized form of the given expression is (k + 2f)(k - f).
Step-by-step explanation:
The given expression is k² + kf - 2f² and we have to factorize the given expression.
k² + kf - 2f² = k² + 2kf - kf - 2f²
= k(k + 2f) - f(k + 2f)
= (k + 2f)(k - f)
So the factorized form of the expression is (k + 2f)(k - f).

The first aircraft has 75 more seats than the second aircraft. The third aircraft has 49 fewer seats than the second aircraft. If their total number of seats is 401, find the number of seats for each aircraft.
1st = 75+x
2nd = x
3rd = x-49
401 = 75 +x+ x+ +x-49
401 = 75+3x-49
401 = 3x+26
375=3x
x=375/3 = 125
1st = 125+75 = 200
2nd = 125
3rd = 125-49 = 76
200 + 125 +76 = 401

We are given that last year sales=$200,000
This year sales increases=250%
We have to find the earn money from this year sales
Let x be the earn money in this year
According to question

A person 6 ft tall casts a shadow 5ft long. at the same time, a nearby tree casts a shadow 31 ft long. find the height of the tree
Therefore, the tree's height is 37.2 feet.
We can use proportions to find the height of the tree based on the shadow it casts and compare it to the height and shadow of a known object (in this case, a person). Given that a person 6 ft tall casts a 5 ft long shadow, we can set up a proportion with the tree's 31 ft long shadow to find its height. The formula we use for this comparison is:
Person's Height / Person's Shadow = Tree's Height / Tree's Shadow
Plugging in the numbers:
6 ft / 5 ft = Tree's Height / 31 ft
Now, we solve for the Tree's Height:
6 ft * (31 ft / 5 ft) = Tree's Height
Tree's Height = 37.2 ft
Therefore, the height of the tree is 37.2 feet.

Final answer:
Using the elimination method, we solved the system of linear equations to find that the solution is x = 3 and y = 1/2.
Explanation:
The student is asking us to solve a system of linear equations. The equations given are:
3x + 2y = 10
2x + 3y = 15/2
To solve these equations, we can use either substitution or elimination method. Let's go ahead with the elimination method to find the values of x and y.
Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x the same:
9x + 6y = 30 (multiplying the first equation by 3)
4x + 6y = 15 (multiplying the second equation by 2)
Now, subtract the second equation from the first equation to eliminate y:
9x + 6y - (4x + 6y) = 30 - 15
5x = 15
x = 3
Now plug x=3 into the first original equation:
3(3) + 2y = 10
9 + 2y = 10
2y = 1
y = 1/2
Therefore, the solution to the system of equations is x = 3 and y = 1/2.
