Answer:
a*b = 1/2
a/ b = 8/9
Step-by-step explanation:
a = 0.66666 and b = 0.75
To multiply it we write the decimal numbers in fraction form
a= 0.666666...
Multiply by 10 on both sides
10 a = 6.66666...
a = 0.66666...
Subtract the second equation
9a = 6
divide by 9 on both sides

so 0.6666 = 2/3
Now we convert 0.75 into fraction form

Multiply top and bottom by 100 to remove decimal

so 0.75 is 3/4
a= 2/3 and b = 3/4


<u>Answer:</u>

<u>Step-by-step explanation:</u>
Given to us is , 5 ( x + 12 ) and we need to find which is its equivalent in the given options .
So,

<h3>
<u>Hence</u><u> </u><u>opt</u><u>ion</u><u> </u><u>C </u><u>is</u><u> correct</u><u>.</u></h3>
Part A) Y cannot be described as a function of x, because in order to be a function, there can only be one input, the x value, for every output, f(x) or the y value. Since the x value, 16, generates two y values, -2 and 2, this cannot be called a function.
Part B)
<span>f(x) = 25x + 16
f(20)= 25(20) + 16
f(20) = 500 + 16
f(20) = 516
This is the total cost, in dollars, of renting the truck for 20 hours. </span>
