Answer:
y=7
x=-7
Step-by-step explanation:
2(-3x - 7y )= 2(-28)
3(2x+ 3y)=3(7)
-6x - 14y = -56
6x + 9y = 21
Add the two equations
-1(0x - 5y)= -1(- 35)
5y = 35
Divide both sides by 5
y=7
Substitution
6x + 9(7) = 21
6x + 63 = 21
Subtract 63 from both sides
6x = -42
Divide both sides by 6
x= - 7
Answer:
The aspect of the lines that are the same is that they have the same slope while the aspect of the lines that are different is that they have different x and y-intercepts
Parallel lines are lines that do not meet in a xy-plane
If the parallel lines are vertical lines, they will both cut the x-axis at different points showing that they will have different x-intercept.
Similarly, if the parallel lines are horizontal lines, they will both cut the y-axis at different points showing that they will have different y-intercept.
Parallel lines are also known to have the same slope. This is the aspect that is common to both lines.

Answer:
BE = 49
Step-by-step explanation:
In triangle BDC
65^2=56^2+BD^2
65^2-56^2=BD^2
4225-3136=BD^2
1089=BD^2
33=BD
In triangle FDE
65^2=63^2+DE^2
4225-3969=DE^2
256 = DE^2
16=DE
since ED+DB=BE
THEREFORE
16+33=BE
49=BE
