Answer:
answer B: (2,-2)
Step-by-step explanation:
First, write the equations on top of each other:
Then, multiply the the second equation by 2 so that we can use elimination of the y-variable:
Next, use elimination to find the value of "x":
So, your x-value is 2.
Now, substitute your x-value into one of your equations, let's take the second equation, 2x-y=6:
Your y-value is -2.
With all your information gathered, you find that the solution to this system of equation is (2,-2).
Answer:
The answer is (b) moved right 3 units and moved down 3 units
Step-by-step explanation:
∵ f(x) = 4^x ⇒ red in the graph
∵ f(x) = 4^(x-3) - 3 ⇒ blue in the graph
∵ x becomes x - 3 ⇒ means:
The graph moved right 3 units
∵ f(x) = 4^x becomes 4^(x-3) - 3 ⇒ means:
The graph moved down 3 units
∴ The answer is (b)
