Since x=8y, subsitute 8y for x in other equation
y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47
subsitute taht for y to find x
x=8y
in (x,y) form
(x,y)

She exhaled deeply, eyeing the brown clock vigilantly. One more hour of utter boredom and suffering. Her afterschool activity had been canceled last minute, meaning she had to wait to be picked up with nothing to do till it would have ended. She sat on a dirty and peeling maroon bench in the schoolyard, her back to the worn soccer pitch. Figuring she might as well find some way to pass the time before finally going home, she began to doodle in her orange and blue notebook.
Step-by-step explanation:
1. yes, they work together to set the scene by providing details to where she is and why. the sentences describe her emotions without making the paragraph boring.
2. for the most part, the reasoning for her being there afterschool could have been mentioned first but the way it is currently written makes sense regardless.
3. the writer could have included transitions to better connect the sentences. but overall, it is well written.
Answer:
781250 
Step-by-step explanation:
Let y is the length of the farm field
Let x is the width of the farm field
Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:
2x + y = 2500 feet
<=> y = 2500 -2x
The are of the farm has the following formula:
A = x*y
<=> A = x(2500 - 2x)
<=> A = 2500x -2
To have the maximum area of field in square feet, we need to use differentials to estimate:
= 2500 - 4x
Set = 0, we have:
2500 - 4x = 0
<=> x = 625 feet.
=> y = 2500 - 2*625 = 1250 feet
So the maximum area of field is:
A = x*y = 625*1250 = 781250
There should be a .94 increase making it be 141.94 at the end of the week.
Answer:yes 3 times 500 = 1500
Step-by-step explanation: because 3 of 500 = 1500
