Answer:
<h2>y = 2</h2>
Step-by-step explanation:
Put x = -13 to the equation -3x + 9y = 57
(-3)(-13) + 9y = 57
39 + 9y = 57 <em>subtract 39 from both sides</em>
9y = 18 <em>divide both sides by 9</em>
y = 2
you'd use the pythagorean theorem.
a^2+b^2=c^2
a is the first leg, b is the second leg, and c is the third leg.
10^2+13^2=c^2
100+169=c^2
269=c^2
take the square root of both sides
16.4=c

Answer:
Greek
Step-by-step explanation:
compare 5/7 and 64/89
5/7 = .71429

The first term is
1(1-1) -4 = -4
The second term is
2(2-1) -4 = -2
The third term is
