Step-by-step explanation:
1) 7x+3y=19
2)2x-7y=12
3) x=5, y=0
4) x=15/2, y=(-63/4)
5) x=9, y=92
6) x=(-2) , y=(-9)
7) x=5, y=(-2)
8) x=2, y=2
Answer:
The answer is A
Step-by-step explanation:
Using PEMDAS you answer parentheses first so
(8-5)2-(2+4) would then be
3*2-6 then you would multiply
6-6 and find the answer of
0
Step-by-step explanation:
is the required answer.

If a^2+b^2=c^2 then it's a right angle
If a^2+b^2>c^2 then it's acute
If a^2+b^2< c^2 then it's obtuse. 3.1^2+3^2. 5^2
1+9. < 25
#3 is obtuse
4. 28^2+45^2. 53^2
2809. 2809
#4 is a right triangle
5. 9^2+11^2. 13^2
81+ 121 =202.> 169
#5 is acute
Answer:
(x - 3) x + 2
Step-by-step explanation:
