find the nonpermissible replacement for the variable x in this expression (x^2)/(2x-4) ? find the nonpermissible replacement for the variable x in this expression (x^2)/(2x-4) ?
Answers
The non-permissible replacements for the variable x in the expression (x^2)/(2x-4) are x = 0 and x = 2.
Explanation:An expression is undefined when its denominator is equal to zero. Therefore, we need to find the values of x that make the denominator, 2x-4, equal to zero.
Solve the equation for x: 2x - 4 = 0 2x = 4 x = 2
Therefore, x = 2 is a non-permissible replacement because it makes the denominator zero.
Additionally, the expression also includes x^2 in the numerator. Since any number multiplied by zero is still zero, dividing any non-zero number by zero results in undefined. Therefore, x = 0 is also a non-permissible replacement.
In conclusion, the non-permissible replacements for the variable x in the expression (x^2)/(2x-4) are x = 0 and x = 2.
2x-3y=13 y=1/2x-7/2 as a substitution problem
Answers
so replace y with 1/2x - 7/2 in ur other equation
2x - 3y = 13
2x - 3(1/2x - 7/2) = 13....distribute through the parenthesis
2x - 3/2x + 21/2 = 13 ...multiply entire equation by 2 to get rid of fractions
4x - 3x + 21 = 26
4x - 3x = 26 - 21...combine like terms
x = 5
2x - 3y = 13
2(5) - 3y = 13
10 - 3y = 13
-3y = 13 - 10
-3y = 3
y = -3/3
y = -1
solution is (5,-1)
What is the simplified form of x + 6/3 - x + 2/3
Answers
The simplified form of the given expression x + 6/3 - x + 2/3 is 8/3 after combining like terms and simplifying the constants.
The question involves simplifying a mathematical expression.
The expression given is:
x + 6/3 - x + 2/3.
To simplify this expression, combine like terms.
Since x is present in both the first and third terms, they cancel each other out.
Next, combine the constant terms 6/3 and 2/3. This results in:
6/3 + 2/3 = (6 + 2) / 3 = 8/3
The simplified form of the expression is therefore 8/3.

The length of a rectangular jewelry box is 3 inches more than twice the width. the perimeter is 18 inches
Answers
Final answer:
The width of the rectangular jewelry box is 2 inches and the length is 7 inches. These dimensions satisfy the given relationship between the length and width and the specified perimeter of 18 inches.
Explanation:
To solve the problem of finding the dimensions of a rectangular jewelry box where the length is 3 inches more than twice the width, and the perimeter is 18 inches, let's define the width of the box as w inches. Subsequently, the length will be 2w + 3 inches, as stated by the relation given in the problem. The perimeter of a rectangle is calculated by the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. We can set up the equation:
18 = 2(2w + 3) + 2w
Solving the equation for w gives us:
18 = 4w + 6 + 2w
18 = 6w + 6
12 = 6w
w = 2
Now that we have the width, we can find the length:
Length = 2w + 3 = 2(2) + 3 = 7 inches
So, the width of the jewelry box is 2 inches and the length is 7 inches.

An employee receives a weekly salary of $340 and a 6% commission on all sales.
Find the employee's earnings for a week with $660 total sales.
Answers
340+.06(660)
$379.60
The employee earns a fixed salary of $340 plus a 6% commission on sales. In a week with $660 in sales, his total earnings would be $379.60.
Explanation:The employee's weekly income is a combination of a fixed salary and a percentage of sales. His fixed salary is $340. From his sales, he earns a 6% commission. So for a week with $660 in sales, the commission would be 6/100 * 660, which equals $39.60. Adding this commission to the fixed salary: $340 + $39.6 = $379.60. So, the employee's overall earnings for the week would be $379.60.

Use the Distributive Property to complete the following statement:
4(x−1)=4x−
1.
–4.

Answers
So, lets expand this problem. The distributive property basically states that multiplying two numbers being added together is the same as multiplying the outer number by the two numbers being added individually, then adding those together. Sounds way harder than it is:
[tex]x(y+z) = xy+xz[/tex]
You can apply this to your problem like this: multiply the 4 by each term in your binomial (your two terms in parenthesis), then simplify.
[tex]4(x-1) = 4x-(4)(-1)= 4x-(-4)[/tex]
(One thing to always remember – at least, in terms of algebra and not necessarily life – two negatives always equal a positive. This is not shown above, however, because the symbol on the end of the given problem is a subtraction sign. Your answer, in this case, is (–4), or B. Hope that clears up any confusion).

Lisa's age is 4 years older than three times Sammy's age. Lisa is 28 years old. Let s represent Sammy's age.
Which equation can be used to solve for Sammy's age?
s + 4 = 28
3s + 4 = 28
4s + 3 = 28
3s = 28
Answers
Sammy's age can be found by using the formula 3s + 4 = 28.
Lisa's age is 4 years more than Sammy's age multiplied by 3.
Assuming Sammy's age is s, Sammy's age multiplied by 3 is:
= 3s
Lisa's age is 4 more than Sammy's age multiplied by 3 which is:
= 4 + 3s
We know that Lisa is 28 years old and Lisa's age is "4 + 3s." Equating those together will give the expression:
4 + 3x = 28
In conclusion, Sammy's age can be found by the formula 4 + 3x = 28.

d = √12^2 + 5^2 = 13
Total lenght is:
2*13 + 24 + 4 = 26 + 28 = 54
X = 24 ft Of Materials

What is the equation of a line that passes through point R(−4, −3) and has a slope of 7?
A: y = 7x + 25
B: y = 7x − 25
C: y = 7x + 3
D: y = −7x − 3
Answers
(x,y) = (-4,-3) is the given point
Turn to slope-intercept form and use these values to find b
y = mx+b
-3 = 7(-4)+b ... plug in the given values
-3 = -28+b
-3+28 = -28+b+28
25 = b
b = 25
since we know that m = 7 and b = 25, the equation y = mx+b turns into y = 7x+25

Write the rule for the nth term of an arithmetic sequence in which a10=46 and d=3
Answers
Final answer:
The rule for the nth term of the arithmetic sequence is given by the formula a_n = 19 + (n - 1)×3, where a1 is the first term of the sequence and d is the common difference.
Explanation:
To write the rule for the nth term of an arithmetic sequence where the 10th term a10 is 46 and the common difference d is 3, we use the formula:
an = a1 + (n - 1)d
We have that:
a10 is the 10th term of the sequence which is 46.
The common difference d is 3.
Firstly, we need to find a1, the first term of the sequence. We can use the given a10 to find a1.
a10 = a1 + (10 - 1)×3
46 = a1 + 9×3
46 = a1 + 27
a1 = 46 - 27
a1 = 19
Now we can write the rule for the nth term:
an = 19 + (n - 1)×3
This formula allows us to calculate any term in the sequence by substituting the desired term number for n.

now we need to make those 2 equations equal to eachother and solve for x because we want to see after how many months both will read the same that is why we set them equal.
