You can use the Pythagorean theorem for this problem.
a^2 + b^2 = c^2
a^2 + 5^2 = 10^2
a^2 + 25 = 100
a^2 = 75
a = 8.66
h = 8.7
Hope this helps =)
Answer: =−20
y=2
Step-by-step explanation:
Solve for xx in -5y-10=x−5y−10=x.
x=-5y-10
x=−5y−10
2 Substitute x=-5y-10x=−5y−10 into x+9y=-2x+9y=−2.
4y-10=-2
4y−10=−2
3 Solve for yy in 4y-10=-24y−10=−2.
y=2
y=2
4 Substitute y=2y=2 into x=-5y-10x=−5y−10.
x=-20
x=−20
5 Therefore,
\begin{aligned}&x=-20\\&y=2\end{aligned}
x=−20
y=2
Answer:
Option D (most probably)
Step-by-step explanation:
It definitely won't be C because Rational numbers need not be terminating. A and B are clearly wrong, so its most probably D
Answer:
for A it's the first answer and for b 15826
