6(3x-5)≤2(9x+7)+10

divide by 2

3(3x-5)≤9x+7+5

3(3x-5)≤9x+12

divide by 3

3x-5≤3x+4

-5≤4

which is true.

Answer:

Step-by-step explanation:

A(10,10) B(b,10b)

ax-2y=30

$a)\\a(10)-2(10)=30\\10a-20=30\\10a-20+20=30+20\\10a=50$

Divide both parts of the equation by 10:

a=5

Hence,

5x-2y=30

5(b)-2(10b)=30

5b-20b=30

-15b=30

Divide both parts of the equation by -15:

b=-2

Thus,

a=5 b=-2

$b)\\A(10,10)\ \ \ \ \ \ B(-2,-20)\\ \displaystyle\\C(x_C,y_C)=(\frac{10+(-2)}{2} ,\frac{10+(-20)}{2} )\\\\C(x_C,y_C)=(\frac{10-2}{2},\frac{10-20}{2} )\\\\C(x_C,y_C)=(\frac{8}{2} ,\frac{-10}{2})\\\\C(x_C,y_C)=(4,-5)\\Hence,\ C(4,-5)$
