Simplify. What are the restrictions on the variable? (2x/x-3)+(6/3-x)
Answers
Answer:
V = 2
x ≠ 3
Step-by-step explanation:
Simplifying
We are given the expression:
[tex]\displaystyle V=\frac{2x}{x-3}+\frac{6}{3-x}[/tex]
To simplify, we make both denominators equal by multiplying the second term by -1:
[tex]\displaystyle V=\frac{2x}{x-3}-\frac{6}{x-3}[/tex]
Now both denominators are equal, we simply add the numerators:
[tex]\displaystyle V=\frac{2x-6}{x-3}[/tex]
Factoring the numerator:
[tex]\displaystyle V=\frac{2(x-3)}{x-3}[/tex]
This expression can be simplified by x-3, but we must take into consideration the x-3 cannot be zero because it would cause an indetermination to appear.
The restriction is:
x - 3 ≠ 0
Or, equivalently:
x ≠ 3
Simplifying:
V = 2
A hairdresser receives a discount on each comb purchased. The original price of each comb is x dollars. The hairdresser purchases 15 combs for a total of (15x-45) dollars. By how much is each comb discounted?
Answers
Answer:
$3
Step-by-step explanation:
Given that:
Price of each comb = $[tex]x[/tex]
15 combs were purchased in = $[tex](15x-45)[/tex]
To find:
Amount of discount offered on each comb.
Solution:
First of all, let us calculate the price of 15 combs at the price of $[tex]x[/tex] each.
Original Price of 15 combs = Price of one comb [tex]\times[/tex] Number of combs = $15[tex]x[/tex]
Now, there is some discount provided on the purchase of 15 combs.
Discount offered on 15 combs = Original price of 15 combs - Discounted price of 15 combs = [tex]15x- (15x-45)[/tex] = $45
Discount offered on each comb = Discount on 15 combs divided by 15
Discount offered on each comb = [tex]\frac{45}{15}[/tex] = $3

Answers
Answer:
solving the equation [tex]5x^2 - 16 = 29[/tex] we get the solution: [tex]\mathbf{x=3,x=-3}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]5x^2 - 16 = 29[/tex]
We need to solve the equation to find the value of x.
We can solve this equation using simple DMAS rule.
We are given:
[tex]5x^2 - 16 = 29[/tex]
Add 16 on both sides
[tex]5x^2 - 16+16 = 29+16\\5x^2=45[/tex]
Now, divide both sides by 5
[tex]\frac{5x^2}{5}=\frac{45}{5} \\x^2=9[/tex]
Now, we know that [tex]\sqrt{x^2}=\pm x[/tex]
Taking square root on both sides.
[tex]\sqrt{x^2}=\sqrt{9}\\x=\pm3[/tex]
So, we get values of x:
[tex]x=3, x=-3[/tex]
Therefore, solving the equation [tex]5x^2 - 16 = 29[/tex] we get the solution: [tex]\mathbf{x=3,x=-3}[/tex]

B: (k-1)(2k+3)
C: (2k-1)(k+3)
D: (k-3)(2k+1)
Answers
Answer:
A
Step-by-step explanation:
Given
2k² - k - 3
Consider the factors of the product of the k² term and the constant term which sum to give the coefficient of the k- term.
product = 2 × - 3 = - 6 and sum = - 1
The factors are + 2 and - 3
Use these factors to split the k- term
2k² + 2k - 3k - 3 ( factor the first/second and third/fourth terms )
= 2k(k + 1) - 3(k + 1) ← factor out (k + 1) from each term
= (2k - 3)(k + 1) → A

5) I think the wrong image is attached, but a point would just be a dot, a line would have one dot then an arrow on the other end, an angle would be 2 lines connected with an emphasis on what's going on in between the 2 lines, a line segment is 2 dots on both ends of a line.

8) line p
9) (-2, 7)
Step-by-step explanation:
For the distance between 2 points, do (x2-x1)^2+(y2-y1)^2 then take the square root of that.
For naming a plane, as long as it is an uppercase cursive letter it is a plane.
Rays are lines without the dot on the end.
Collinear points are points that lie on the same line.
Midpoint method is finding the average between the x coordinates then the y coordinates, so think (x1+x2)/2, (y1+y2)/2, but this can be confusing with negative distances, so just think of it as on a number line, from -1 to -3 they are 4 apart, so the average between them is -2.

Find the value of x in the triangle shown below
Answers
Answer:
x=50
Step-by-step explanation:
since its an isosceles triangle, both of the base angles are going to be the same. Since all of a triangle's angles combined equal 180, and you already have one angle, subtract the 80 from 180.
this leaves you with 100. since there are two angles left, divide 100 by two and thats the value of x
hope this helps!! :)
Answer:
50?
Step-by-step explanation:
I would say 50 because x and the blank angle looks the same and 80+x+?=180
80+x2=180
x*2=100
x=50

The square root of the quotient of a number n and 3 is equal to the square root of 4 less than the number. Which of the following is the value of n?
Answers
Answer:
6
Step-by-step explanation: You can set up the equation: [tex]\sqrt{\frac{n}{3} }[/tex] = [tex]\sqrt{n-4}[/tex] You square both sides to cancel out the squares which leaves you with [tex]\frac{n}{3}[/tex] = n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with [tex]\sqrt{2}[/tex] on both sides.
