which correctly explains the number of solutions of the following system of linear equations? -3x + 3y = 12 y = x + 4
A. The Graphs of the equations are parallel lines because they have the same slope but different y-intercepts. The system has no solution
B. The graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. The system has exactly one solution
C. The graphs of the equations are lines that intersect at one point because the equations have the same slope and same y-intercept. The system has exactly one solution.
D. The graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has exactly Infinitely many solutions.
Please explain how you got the answer because I need to learn it.
Answers
The system has an infinite number of solutions because the equations have the same slope and y-intercept, and the graph of the equations is the same line.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The system of equations is given in the question, as follows:
-3x + 3y = 12
y = x + 4
When all the given equations are drawn in the graph, then we get the Infinitely many solutions ordered pairs in the solution set of the given system.
Here, the graph of the equations is the same line because the equations have the same slope and the same y-intercept. The system has exactly Infinitely many solutions.
Therefore, the correct answer would be an option (D).

#SPJ2
In the Japanese game show Sushi Roulette, the contestant spins a large wheel that’s divided into 12 equal sections. Nine of the sections have a sushi roll, and three have a “wasabi bomb.” When the wheel stops, the contestant must eat whatever food is on that section. To win the game, the contestant must eat one wasabi bomb. Find the probability that it takes 3 or more spins for the contestant to get a wasabi bomb. Show your method clearly.
Answers
Answer:
P = 0.545
Step-by-step explanation:
Here we can find the probability Q, in which you need one or two spins to win the game, and then:
P = 1 - Q
Will be the probability that it takes 3 or more spins to win.
Case where you need only one spin:
There are 3 out of 12 possible outcomes, then the probability of winning with only one spin is:
p = 3/12.
Case where you need two spins to win:
Here we should get a normal sushi roll in the first spin and a wasabi bomb in the second.
The probability of getting a sushi roll in the first spin is equal to the quotient between the number of sushi rolls (9) and the total number of possible outcomes (12), then:
p1 = 9/12
For the second spin we need to get a wasabi bomb, assuming that the susi roll is not replaced (so now there are 8 sections with sushi rolls and 3 with wasabi bombs, if you get the empty section you roll again or something like that)
Now the probability of getting a wasabi bomb is equal to the quotient between the number of wasabi bombs remaining (3) and the total number of outcomes remaining (11), this is:
p2 = 3/11
The joint probability is the product of the two individual probabilities:
p = p1*p2 = (9/12)*(3/11)
Now, the total probability of winning with one or two spins is equal to the sum of the probabilities for each case, then:
Q = (9/12)*(3/11) + 3/12 = 0.455
Then the probability of needing 3 or more spins to win is:
P = 1 - Q = 1 - 0.455 = 0.545
The probability that it takes 3 or more spins for the contestant to get a wasabi bomb is 0.545 and this can be determined by using the given data.
Given :
In the Japanese game show Sushi Roulette, the contestant spins a large wheel that’s divided into 12 equal sections. Nine of the sections have a sushi roll, and three have a wasabi bomb.When the wheel stops, the contestant must eat whatever food is on that section. To win the game, the contestant must eat one wasabi bomb.The probability to win the game in the first spin is:
[tex]\rm P_1=\dfrac{3}{12}=\dfrac{1}{4}[/tex]
The probability to win the game in the second spin is:
[tex]\rm P_2 = \dfrac{9}{12}\times \dfrac{3}{11}[/tex]
[tex]\rm P_2=\dfrac{9}{44}[/tex]
The probability to win in 1 or 2 spins is given by:
[tex]\rm Q = P_1+P_2=\dfrac{9}{44}+\dfrac{1}{4}[/tex]
Q = 0.455
So, the probability that it takes 3 or more spins for the contestant to get a wasabi bomb is:
P = 1 - Q
P = 1 - 0.455
P = 0.545

Question 3. Find the distance between P(4,5) and the line with equation 8x + 5y = 20
Answers
Answer:
Step-by-step explanation:
8x+5y = 20
y = (-8/5)x + 4
slope of the line is -8/5.
slope of any perpendicular to the line is ⅝.
line of slope ⅝ that passes through P(4,5):
y-5 = ⅝(x-4)
y = ⅝x + 2.5
find intersection of lines
⅝x + 2.5 = (-8/5)x + 4
25x + 100 = -64x + 160
89x = 60
x = 60/89, y = 260/89
distance between (60/89, 260/89) and (4,5) = 3.92

Answers
Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.
A cube has a volume 1,000 cubic feet. What is the length of the edge of the cube. SHOW YOUR ANSWER
Answers
Answer:
10ft
Step-by-step explanation:
The length of one side of this cube would be the cube root of 1000 since each of the three dimensions are the same. You could solve this problem with the following equation, where [tex]l[/tex] is the side length.
[tex]l^3[/tex] = 1000
[tex]l[/tex] = [tex]\sqrt[3]{1000}[/tex]
[tex]l[/tex] = 10
So, the side length of the edge of the cube is 10ft.

Answer:

Step-by-step explanation:
The easiest way to start this is to add the two values together to find the total amount of participants.
154+136=292
To find the percentage of males in the population, we need to divide the amount of men by the total population.
154/292=0.527397
The percentage of men is 53%.
