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

Yohan Blake ran the 100-meter race in the 2012 Olympics in 9.75 seconds. Compare the speeds if he ran the 200-meter race in 19.5 seconds.
Sorry for the late response :<
Answer:
The unit rates would be comparable for both races. So, his speed is going to be the same for both races.

Leyla will roll a number cube 1-4 and flip a coin. The coin can land on heads or tails. If Leyla rolls the number cube once and flips the coin once, which list contains only the outcomes in which the number cube land on a number greater than 3?
Answer:
[tex]Outcome = \{4H,4T\}[/tex]
Step-by-step explanation:
Given
A roll of cube numbered 1 - 4
A flip of coin
Required
Determine the possible outcomes for a number greater than 3
First, we list the sample space of the coin:
[tex]Sample\ Space = \{1,2,3,4\}[/tex]
Next, we list outcomes greater than 3
[tex]S = \{3\}[/tex]
Next, we list out the sample space (C) of a flip of coin:
[tex]C = \{H,T\}[/tex]
Where
[tex]H = Head\\T = Tail[/tex]
So, the possible outcome for a number greater than 3 is:
[tex]Outcome = \{4\} + \{H,T\}[/tex]
[tex]Outcome = \{4H,4T\}[/tex]
What is the circumference of the circle below?
Answer:
Step-by-step explanation:
circumference C=2*3.14*r
C=2*3.14*18m=113.04 m
Answer:
113.04 meters.
Step-by-step explanation:
Use the formula
2 times pi times r
r=radius of the circle
or Pi times D
d= diameter of the circle.
The radius is 18 meters.
So, do 2 times 18 times pi.

Simplify. What are the restrictions on the variable? (2x/x-3)+(6/3-x)
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

Jack will spend a total of exactly $15 on Redbix movies and games. What equation in standard form can he use to graoh a line showing the different amounts of movies at $1.25 and games at $2.50 he can buy
Answer:
[tex]1.25x+2.5y -15 = 0[/tex]
Step-by-step explanation:
Total amount to be spent on Redbix movies and games = $15
Money to be paid for each movie = $1.25
Money to be paid for each game = $2.50
To find:
Equation in standard form that can be used to graph the line.
Solution:
First of all, let us learn about the standard form of equation of a line.
Standard form can be represented as:
[tex]Ax+By+C =0[/tex]
Where [tex]A,B, C[/tex] are constants.
Now, let us try to make equation.
Let number of movies bought = [tex]x[/tex]
Amount to be paid for movies = $1.25[tex]x[/tex]
Let number of movies bought = [tex]y[/tex]
Amount to be paid for movies = $2.50[tex]y[/tex]
Total money is $15.
Therefore, we can write the equation as:
[tex]1.25x+2.5y = 15[/tex]
Standard form can be written as:
[tex]1.25x+2.5y -15 = 0[/tex]

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

A salesperson gets a commission of 4% on all sales up to $8000 and a commission of 6% on all sales over $8000. What is the commission earned on sales of $12 500?
Answer:
The commission earned on all sales over
$12 500 is $750
Step-by-step explanation:
$12 500 is over $8000 so the commission is 6%
Turn the percentage into a decimal
[tex]6 \div 100 = 0.06[/tex]
Multiply that decimal with the earned sales price
[tex]0.06 \times 12500[/tex]
= $750
