In the diagram, x is a negative number and y is a positive number. Select the expression that is a positive.
Answer choices:
x(y)
x - y
y/x
y - x
Answer:
Option 4: y -x
Step-by-step explanation:
Option 1
Multiplying a positive and a negative number will result in a negative number.
For example, if x= -1 and y=5,
x(y)= -1(5)= -5 (a negative number)
Thus, option 1 is incorrect.
Option 2
In this option, we are essentially multiplying -1 to y, a positive number, before adding the result with x.
Since y is a positive number, -y is a negative number and hence x -y (when x is a negative number) will result in a negative number. Let's plug in values into x and y to check this.
For example, x= -2 and y=3.
x -y= -2 -3= -5
Option 2 is thus incorrect.
Option 3
Dividing a positive number with a negative number will result in a negative number.
For example: 6÷(-2)= -3
Option 3 is also incorrect.
Option 4
Subtracting a negative number from a positive number will result in a positive number.
For example: x= -1, y= 8
y -x= 8 -(-1)= 8 +1= 9
As seen from the example above, when the negative number is multiplied to negative 1, a positive sign results.
In summary, when a positive number is multiplied to a positive number, the resulting number is positive.
When a negative number is multiplied to a negative number, the resulting number is positive.
When a positive number is multiplied to a negative number, the resulting number is negative.
+(+)= +
-(-)= +
+(-)= -
This applies to division too.
Equation C: y = 6x + 9 Equation D: y = 6x + 2 How many solutions are there to the given set of equations?
Answer:
No solution
Step-by-step explanation:
Equation C :
y = 6x + 9
Equation D :
y = 6x + 2
By comparing both the equations with slope-intercept form of the equation,
y = mx + b
Where, m = Slope of the line
And b = y-intercept
Slopes of both the lines C and D are common as 6,
Therefore, both the lines will be parallel.
And the set of parallel lines has no solution.
Therefore, given set of equations have no solution.

Jim wants to buy a new tablet for his homework. His budget is $350. If the tablet costs $330 plus 4.5% sales tax, can he buy it for $350 or less?
Answer:
Yes, he can buy it for $350 or less
Step-by-step explanation:
330.00 x 4.5%
330.00 x 0.045 = 14.85
330.00 + 14.85 = 344.85
or
330.00 x 1.045 = 344.85

EMERGENCY!!!! Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answers I got were 384 and 64 and they were both wrong)
Answer:
After eight hours 6,561 people will know the rumor.
Step-by-step explanation:
Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:
Hour 0 = 1
Hour 1 = 1 + 2 = 3
Hour 2 = 3 + 2 x 3 = 9
Hour 3 = 9 + 2 x 9 = 27
Hour 4 = 27 + 2 x 27 = 81
Hour 5 = 81 + 2 x 81 = 243
Hour 6 = 243 + 2 x 243 = 729
Hour 7 = 729 + 2 x 729 = 2,187
Hour 8 = 2,187 + 2 x 2,187 = 6,561
Therefore, after eight hours 6,561 people will know the rumor.

Ed solved a puzzle 3/4 faster than Brett. Brett solved the puzzle in 135 seconds. How long did it take Ed to solve the puzzle.
Answer:
101.25 seconds.
Step-by-step explanation:
We know that Ed solved the puzzle 3/4 faster than Brett.
Then if Brett solved the puzzle in a time T, Ed solved the puzzle in a time (3/4)*T.
We know that Brett solved the puzzle in 135 seconds, then:
T = 135s
This means that Ed solved the puzzle in:
time = (3/4)*T = (3/4)*135s = 101.25 seconds.

Seth bought glow-in-the-dark stars to
put on his ceiling. There are 5 big stars
and 25 little stars. He wants to make
constellations that each have 1 big
star. If he uses the same amount of
stars for each constellation, how many
little stars will each have?
Answer:
Each constellation will have 5 little stars.
Step-by-step explanation:
First, let's organize the information we have:
5 big stars25 little starsEach constellation should have 1 big starEach constellation should have the same amount of starsNow, let's solve the problem:
Each constellation should have 1 big star, and Seth has 5 big stars, so we can infer that there would be 5 constellations.Since each constellation have 1 big star, and the amount of stars in each constellation is the same, the amount of little stars in each constellation are the same.We have 25 little stars, and there are 5 constellations; 25 ÷ 5 = 5, so each constellation have 5 little stars.Find the indicated side of the
