Is it possoble for a system of linear equations to have no solution

Vera_Pavlovna [14]

Yes This Is Possible. This Would Happen If The Lines Never Intersected With Each Other. If This Was The Case, There Would Be No Point That Lies On Both Lines. Have A Great Day!

The sum of two numbers is 13 and there difference is 5 what are the 2 numbers?

Zielflug [23.3K]

X + y = 13
x - y = 5

x = (13 - y)

(13-y) - y = 5

13 - 2y = 5
-2y = -8
y = 4

x - 4 = 5
x = 9

x=9, y = 4

Have I been solving these equations correctly?

2(-3)² => 2(-3)(-3) => 2*9 = > 18

27+18-11 => 27 + 7 = > 34.

16)

$\bf p(x)=\cfrac{x^2-4}{2x+1}\implies p(-8)=\cfrac{(-8)^2-4}{2(-8)+1}\implies p(-8)=\cfrac{64-4}{-16+1} \\\\\\ p(-8)=\cfrac{60}{-15}\implies p(-8)=-4$

17)

$\bf h(x)=3\cdot 9^x\implies h(-2)=3\cdot 9^{-2}\implies h(-2)=3\cdot \cfrac{1}{9^2} \\\\\\ h(-2)=\cfrac{3}{9^2}\implies h(-2)=\cfrac{3}{81}\implies h(-2)=\cfrac{1}{27}$
