Over 5 straight plays a football team gained 8 yards lost 4 yards
melomori [17]
Over 10 straight plays they would have 16 gained years and 8 lost yards. over 20 straight plays the would have 32 yards gained and 16 lost yards. what you do to find out how to do this is dividing the yards gained and the yards lost and then multiplying all the numbers by the number you got.

12. Write the equation of the line passing through the point (2,6) with slope 4 in
stepladder [879]

Answer:

y = 4x - 2

Step-by-step explanation:

slope = 4

y -6 = 4 ( x- 2 )

distribute the 4 to ( x - 2 )

y - 6 = 4x - 8

add 6 to both side

y = 4x - 2

Hopefully this helps you understand this concept.

I think I have the correct answers but will anyone try to solve these questions so I can see if we got the same answer.
Andre45 [30]

Because you seem to have an understanding of the material, I will write my math, but no explanations for my work. Comment on this answer for an explanation, or if I did something wrong.

1. Find the length of the South side of the field.

(5x+2)+(x^2-9)+(x^2-7x+12)\\5x+2+x^2-9+x^2-7x+12\\2x^2+5x+2-9-7x+12\\2x^2-2x+2-9+12\\2x^2-2x+5

2.Find the perimeter of the pumpkin field.

2(5x+2)+2(5x-2)\\(5x+2)+(5x+2)+(5x-2)+(5x-2)\\20x+4-4\\20x

3. Find the perimeter of the whole field.

2(4x+5x-2)+2(5x+2+x^2-9+x^2-7x+12)\\2(9x-2)+2(2x^2-2x-5)\\18x-4+4x^2-4x+10\\4x^2+14x+6

4. If x=30ft, what is the total perimeter?

P=4x^2+14x+6\\P=4(30)^2+14(30)+6\\P=4(900)+420+6\\P=1026ft

Random Tangent:

If you want to involve y in finding these answers for whatever reason, your math is going to get messy. Here's what I tried before I realized you could multiply each side by 2 to get the total perimeter:

xy+1+x+6=4x+5x-2\\xy-8x=-9\\x(y-8)=-9\\y-8=-\frac{9}{x}\\y=-\frac{9}{x}+8

Now the other side. This one's even worse.

xy-1+6x+x=5x+2+x^2-9+x^2-7x+12\\xy+9x-2x^2=5\\x(y+9+2x)=5\\2x+9+y=\frac{5}{x}\\y=\frac{5}{x}-2x-9

At this point, was realizing I wasn't going about the problem correctly, but did one last try by setting y=y. At this point in the equation, I simply had to stop, both due to complexity and technological problems.

\frac{5}{x}-2x-9=-\frac{9}{x}+8\\\frac{14}{x}=2x+17\\ 14=2x^2+17x\\0=2x^2+17x-13\\

I could possibly continue to solve, but I don't see a point. It was clear that this was NOT the right path to take finding the perimeter. It was here I realized that I could just multiply the two sides without y in them by 2 and--without as much difficulty--reach the correct answer.
