A consistent system has at least one solution
Answer:
10. 7 + 4a
11. 7a + 4
12. 12a - 4
13. 14(a - 4)
14. 2a + b
15. 2(a + b)
16. 1/3x - 5
17. 3x/8
18. ab / a+b
Step-by-step explanation:
Let x be the number.
Can't explain, I need to do homework.
Hope this helps :)
We have that
point B (-3,-2)
point C (0,2)
the distance between B and C is
d=√(y2-y1)²+(x2-x1)²--------> d= √(2+2)²+(0+3)²-------> d=√25
d=5 units
the answer is
<span>the length of segment BC is 5 units
using a graph tool
see the attached figure</span>
Answer:
Area_ACD = [AC*CD*sinC]/2
Area_BCE = [BC*CE*sinC]/2
AC*CD = BC*CE (as Thales theorem AC/CE = BC/CD)
Then, Area_ACD = Area_BCE
Answer:
30 i think because 3x is 90
