6x + 3y = 9
Ganezh [65]
Solution 1 ▶6(x )+ 3(y) = 9  

Solution 2 ▶2(x) + 3(y) = 1

Graphic organizer ▶3(y) + 6(x) = 9⬇
3(y)+ 2(x) = 1

Solution 2⬇
keep in mind the '2' becomes a negative!

▶3(y) = -2(x) + 1
▶(y) = -2(x) ÷ 3 + 1 ÷ 3

Solution 1⬇
x-intercept

6(x )+ 3(-2)(x)÷3+1÷3) = 9  
▶ 4(x) = 8
▶4(?) = 8
▶x = 2

y-intercept⬇

  ▶(y) = -2(x)÷3+1÷3
  ▶(y) = (-2÷3)(2)+1÷3 = -1 
▶y= -1

x-intercept: 2
y-intercept: -1

So, therefore your answer for this problem would have to be option A. x =2 , y = -1

The graph of g(x) is a transformation of the graph of f(x)=3^x .
marshall27 [118]

f(x)=3^x\\\\g(x)=3^{x+a}+b\\\\\text{We have the points (-2, 2) and (-1, 4). Substitute:}\\\\\underline{+\left\{\begin{array}{ccc}2=3^{-2+a}+b\\4=3^{-1+a}+b\end{array}\right}\qquad\text{subtract both sides of the equations}\\.\ \ -2=3^{-2+a}-3^{-1+a}\\-2=3^{-2}\cdot3^a-3^{-1}\cdot3^a\\-2=\dfrac{1}{3^2}\cdot3^a-\dfrac{1}{3}\cdot3^a\\-2=\left(\dfrac{1}{9}-\dfrac{1}{3}\right)\cdot3^a\\-2=\left(\dfrac{1}{9}-\dfrac{3}{9}\right)\cdot3^a\\-2=-\dfrac{2}{9}\cdot3^a\qquad\text{multiply both sides by}\ -\dfrac{9}{2}

3=3^a\\3^a=3^2\to a=2\\\\\text{substitute value of a to the second equation}\\\\3^{-1+2}+b=4\\3^1+b=4\\3+b=4\qquad\text{subtract 3 from both sides}\\b=1\\\\Answer:\ \boxed{g(x)=3^{x+2}+1}
