Please Help: Determine which ordered pair is a solution of y = x^2 - 2. A) -2,6
B) 5, 21
C) -1, -1
D) -5, 24

Answers

Answer 1

Answer: The answer is C
The term "ordered pairs" refers to graphing and so it will always be in the order of x,y....x first and then y, ALWAYS, so this tells you that in every potential answer given, that the first number IS x and then
to solve for y (the second number) you must do as the equation states and square x,(the first number in the ordered pair you are testing), (squaring means to times it by itself) and then subtract 2, the answer to that, will give you the solution for y.....so......so try this out for all of the above listed potentially correct answers, only ONE will work out properly
Important: to do the equation, you must remember that a negative times a negative ALWAYS equals a positive....so
-1 * -1 = 1.....then the last step, subtracting 2 (-2)
1 -2 = -1......thus C : -1, -1.... is the only possible answer

You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage.

A bag contains 5 black marbles and 4 white marbles. A spinner has 3 equal sections labeled 1 through 3. What is the probability of drawing a black marble from the bag and spinning a 1 on the spinner?

Answers

$5+4=9 \leftarrow \text{marbles in total}$

$\text{The probability of drawing a black marble is } (5)/(9)$

$\text{The probability of spinning a 1 is } (1)/(3)$

$\text{The probability of both is } (5)/(9)\cdot(1)/(3)=(5)/(27)$

Ms brown divided her class into equal groups two eighths of 48 students went to math how many students went to math

Answers

12 students went to math because 1/8 would be 6 and you would just add another eighth, which would be 12.

Well to answer this question you need to divide 48 by 8, and then multiply that answer by 2.
48/8=6 6*2=12

NEED ANSWER ASAP!!A-1 Deli sells jugs of iced tea that they have marked up 150% above their wholesale cost of $0.80 per jug. They also charge sales tax of 9%. What is the total cost of a jug of iced tea from A-1 Deli?

1. $1.27
2. $1.31
3. $2.00
4. $2.18

Answers

Answer:

Option 4: $2.18

Step-by-step explanation:

Lets first analyse our given information. We know that:

- Original Cost Per Jug: $0.80

- Mark Up cost: 150%

- Sales Tax: 9%

Now the Mark Up cost essentially means that the original price of any item has gone up (i.e. increased). So first let us find the Mark Up final cost of a $0.80 jug when price has increased by 150%, as follow:

$0.80+0.80(150)/(100) =0.80 + 1.2=2$
