Step-by-step explanation:
Factor 2k^2 - k - 3
A: (2k-3)(k+1)
B: (k-1)(2k+3)
C: (2k-1)(k+3)
D: (k-3)(2k+1)
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

4(x-7)+12 = 16
Answer:
x = 8
Step-by-step explanation:
do distribution: 4x - 28 + 12 = 16
simplify: 4x - 16 = 16
add 16 to both sides: 4x = 32
divide both sides by 4: x = 8

Austin correctly answered 80% of the questions on the geography quiz. Liz answered 42 of the 50 questions correctly. compare their scores
Answer:
Liz got a higher score than Austin.
Step-by-step explanation:
Since 42 divided by 50 is 82, as a percentage is then 82%. Austin has a 80% which most likely means, if on the same quiz, that he got a 40 out of 50.

4) Ray
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.
6)H N K I
7) (2,-8)
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.
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?
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.

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?
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
