Answer:
122
Step-by-step explanation:
If a number has an explanation point on the side of it, you should multiply all numbers that are equal to are less than that number.
What is the solution to the system of equations?
1 answer:
Answer:
A: There is no solution
Step-by-step explanation:
This is not a very likable question.
Y=3x-4
9x-3y=14
Put the y value from the first equation into the second.
9x - 3(3x - 4) = 14 Remove the brackets
9x - 9x + 12 = 14 Combine like terms on the left
12 = 14 When you get this kind of conclusion, that means there is no solution. I'll graph these two for you.
Blue: y =3x - 4
Green: 9x - 3y = 14
They never touch they never meet: they are parallel. They don't give a solution.

Please find attached, the required graph created on MS Excel
Step-by-step explanation:
The distance between Sandy's house and the school = 200 m
The number of minutes Sandy talked to her friend for = 10 minutes
The time it took Sandy to return home to pick her homework = 5 minutes
Let <em>x </em>represent Sandy's location she stops to talk to her friend 10 minutes, we have;
The slope of the motion on the graph, m₁ = (x - 0)/(t - 0)
The slope of her motion running home to pick the up her homework, m₂ = (x - 0)/(5 - 0)
Given that t > 5, the slope on trip back home, m₁, is larger than are her initial slope, m₂
Therefore, where x = 125, we have;
The rate at which she returned home = m₂ = (125 m - 0)/(5 min - 0) = 25 m/min
Given that the same rate m₂ is what she used in heading back to school, we have;
The time it takes her to get to school = 200 m/(25 m/min) = 8 minutes
Therefore, whereby it took her 10 minutes to reach point <em>x</em>, we have the following coordinate points on the graph in a tabular form;
The plot of the above point is completed using MS Excel as shown in the attached diagram.
