F(2x-5)=14x-35
G(4x+3x)=14x-5
The answer is 28 units squared
Answer:
First, Juliana should write the function as an equation that equates to f(x). She can do this by translating each of the action phrases stated in the question into the form of an expression.
Take the equation f(x) and find its inverse. In the equation, change f(x) to the y variable and switch the x and y variable. Then, isolate y by moving all values to the other side of the equal sign in the backwards order of operations. The y variable should then be changed to f⁻¹(x).
In the inverse function, substitute x for twenty-four and solve. In the final answer, leave in decimal form, rounded down if needed.
Something is missing in right hand side
20% off means they will be 80% of their original price. Obviously, we can answer the question as a percentage without even thinking. We will save 20% of the ultimate price.
The first step is to find the cost of everything at 80%.
2.00, 3.96, and 4.80
That adds up to 10.76
The original cost would have been 13.45, so you saved 2.69
