Answer: 2x-3=15
2(9)-3=15
18-3=15
Answer:
x=1, y=-1. (1, -1)
Step-by-step explanation:
2x-3y=5
x+2y=-1
---------------
2x-3y=5
-2(x+2y)=-2(-1)
-----------------------
2x-3y=5
-2x-4y=2
-------------
-7y=7
y=7/-7
y=-1
x+2(-1)=-1
x-2=-1
x=-1+2
x=1

Answer:
a = 7
Step-by-step explanation:
The Pythagorean theorem tells you the value of 'a' is ...
a^2 = b^2 - c^2
a^2 = 25^2 -24^2 = 625 -576 = 49
a = √49 = 7
The length of side 'a' is 7 units.
Answer:
Your answer would be the first option.
