love ya
<span>-3x + 2y = 2 eq (1)
7x - 3y = 7 eq (2)
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1)
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)
Answer: option B. (4,7)

Yes i believe thats it ok
Answer:
acute: D and E
obtuse: A and F
right: B
straight: C
Step-by-step explanation:
You can solve it as 3*500+3*80+3*4. It the same as solving it normally, since you're essentially solving it as above (one place value at a time).
