Answer:
5x-1
Step-by-step explanation:
8x-3(x+1)-4
{open the brackets}3x-3
8x-3x-3-4
5x+(-7), which is 5x-7
1) You can make about 6 bracelets because 43 divided by 6.8 is 6.3235 so you round it to 6.
2) The answer is 14.4 miles because that’s what 3.6x4 equals.
3) The answer would be $63.09 because 7.01x9=63.09
4) The answer is 1.35 , you just have to multiply 0.5 and 2.7
5) The answer is 9.432 seconds
6) For aluminum it would be $1.15 and for copper it would be $3.24
7) 0.21 x 10 = 2.1
8) 45.35 divided by 10,000 = 0.004535
9) 6.02 x 0.1 = 0.602
10) 9.4 divided by 0.01 = 940
11) 15.5
12) $695

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.
