The solution set is (7,3).

Step-by-step explanation:

Given system of equations is;

3x−2y=15     Eqn 1

y=2x−11        Eqn 2

Substituting value of y from Eqn 2 in Eqn 1

3x-2(2x-11)=15\\3x-4x+22=15\\-x+22-15=0\\7=x\\x=7

Putting x=7 in Eqn 2

y=2(7)-11\\y=14-11\\y=3

The solution set is (7,3).

Keywords: linear equation, substitution method

A) x=90, y=47<br> B) x=47, y=43<br> C) x=43, y=47<br> D) x=90, y=43
fomenos
D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.

F(x)=1/x and g(x)=x-4<br> Can you evaulate (g o f)(0) explai sn why or why not
Ostrovityanka [42]

Hello from MrBillDoesMath!

Answer:

 (g o f)(0) cannot be evaluated

Discussion:

(g o f)(0) = g ( f(0))  if it exists but f(0) is not defined (as division by zero is not defined) so   (g o f)(0) cannot be evaluated

Thank you,

MrB
