Answer:
The independent variable is m (the number of miles driven), and the dependent variable is "e" (the cost)
Step-by-step explanation:
Notice that the cost "depends" upon the number of miles driven, therefore, the cost (identified with the letter "e") is the dependent variable which depends upon the number of miles driven (and which is the independent variable identified with the letter "m")
Answer:
Um... Don't see the question but here's the answer
Step-by-step explanation
90 has more squares because 0.90 has one more 0 in it and it has 9th of the 10ths than 9
Answer:
f^-1(x) = (x-1)/-3
Step-by-step explanation:
Invert equation:
Describe X in original function:
multiplied by -3
add 1
Reverse order:
subtract 1
divide by -3
It is 100 times smaller because 1.95x100=195 !!!
Answer:
combined variation
Step-by-step explanation:
we have

we know that
a)<u> in the interval </u>----> (0,∞)
If the value of x increase the value of y increase
so
Is a direct variation
b) <u>in the interval -</u>---> (-∞,0)
If the value of x increase the value of y decrease
so
Is a inverse variation
therefore
Is a combined variation
