Answer: C
Step-by-step explanation:
Proof in picture.
You use Pythagorean theorem to solve this problem.a^2+b^2=c^2
A.53*53=45*45+28*28
2809=2025+784
2809=2809
B.85*85=13*13+84*84
7725=169+7056
7725=7725
C.85*85=36*36+77*77
7725=1296+5929
7725=7725
D.65*65=16*16+61*61
4225=256+3721
4225=3977
The answer is D
10^-5 = 0.00001
27 divided by 0.0001=2700000

Answer:
D. 2x + 7
Step-by-step explanation:
Use the point given, (-3, 1), and put it into the point-slope formula.
y - 1 = m(x+3)
The m, or the slope, is still blank. When you want a line parallel to a certain slope, the slope remains the same. Therefore, you plug in 2 for m:
y - 1 = 2(x+3)
y - 1 = 2x + 6
y = 2x + 7
