The graph shows two lines, A and B.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.
Part B: What is the solution to the equations of lines A and B? Explain your answer
Answer:
A: 1 solution
B: (4,4) is the solution
Step-by-step explanation:
They have different slopes so they're already different equations and because of that, they can only have one solution.
The intersection of the two lines is the solution since those coordinates satisfy both equations.
Answer:
Part AThe solutions of a graphed pair of equations are the points of intersection - the points on the graph where the two lines cross each other. At this point, when inputting the same x-value into the 2 equations, the resulting y-values will also be the same.
Therefore, from inspection of the graph, there is one point of intersection, and so one solution.
The name for a system that has one solution and intersects at one point is Consistent Independent
Part BFrom inspection of the graph, the point of intersection is (4, 4).
Therefore, the solution to the equations of line A and B is (4, 4).
Proof
Equation of line B: y = xEquation of line A: y = -0.5x + 6Using substitution:
⇒ x = -0.5x + 6
⇒ 1.5x = 6
⇒ x = 4
Substituting the found value of x into one of the equations to find y:
⇒ y = 4
Therefore, the solution is (4, 4)
20 POINTS FOR PART B)
The number of toys owned by eight classmates is shown below:
4, 3, 4, 5, 6, 6, 8, 4
Part A: What is the mean of the data? Show your work. (4 points)
Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work. (6 points)
Part A:
The mean of the data is 5 because you add all the numbers otgether then divided it by 8 (the number of classmates). 4 + 3 + 4 + 5 + 6 + 6 + 8 + 4 = 40 then divided by 8 is 5.
A spinner with four sections is spun 30 times.
Color Number of times
Red 7
Yellow 8
Blue 6
Green 9
Based on these results, what is the experimental probability that the next time the spinner is spun, it lands on green?
A. 1/5
B. 3/10
C. 4/15
D. 7/30
Answer:
3 / 10
Step-by-step explanation:
Total = 30 times
n ( T ) = 30
Green = 9
n ( G ) = 9
To find : Probability of Green [ P ( G ) ]
Formula : -
P ( G ) = n ( G ) / n ( T )
P ( G ) = 9 / 30
9 = 3 x 3
30 = 3 x 10
P ( G ) = ( 3 x 3 ) / ( 3 x 10 )
P ( G ) = 3 / 10
Hence,
the experimental probability that the next time the spinner is spun, it lands on green is 3 / 10.

PLEASE HELP I WILL GIVE 20 POINTS!
Answer:
it says there are only 10, not 20?
Step-by-step explanation:
Please give step by step explanation and answer,
Answer:it would be C.
Step-by-step explanation:
6-(-6)=12 and 5-(-3)=8, so if you put it in the fraction, it would end up as 3/2.
3-(-3)=6 and 3-(-1)=4, and 6/4 simplified is 3/2. If both slopes are 3/2, then they would be parallel, showing that the two lines have the same slope. Another way to prove is that 3/2=3/2 is true
