Answer:
2677
Step-by-step explanation:
Let's make this easier first of all:
a^2-y^3(a-y^2)y^2
a^2-y^5(a-y^2)
a^2-ay^5+y^7
(-2)^2-(-2)(3)^5+3^7
4-(-2*243)+2187
4-(-486)+2187
4+486+2187
490+2187
2677
Answer:
Tommy and Manuel are 16 ft apart
Step-by-step explanation:
The locations of all three players are shown in the image below
They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.
We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then

Knowing c and one of the legs, say b:

Using the values c=20, b=12 we find


So, Tommy and Manuel are 16 ft apart
You could get two different functions out of this:
<u>2x + 2y = 8</u>
1). <u> 'y' as a function of 'x'</u>
Subtract 2x from each side: 2y = -2x + 8
Divide each side by 2 : <em> y = -x + 4</em>
2). <u> 'x' as a function of 'y' :</u>
Subtract 2y from each side: 2x = -2y + 8
Divide each side by 2 : <em> x = -y + 4</em>
Those two functions look the same, but that's just because the original
equation given in the problem was so symmetrical. In general, they're
not the same function.
