Maybe around 10 this is a tricky question.
Different dealerships sell different amounts
We see nothing below that makes the situation clear for us.
We have no way to know what the angles 'x' and 'y' are, or
even whether they're on the same planet as the circle.
Answer: D
Step-by-step explanation:
I just took it
The total charges for the first club as a function of the number of rentals (x) are
... f1 = 25 + 2.50x
The total charges for the second club are
... f2 = 3.25x
We want to find x so that f1 < f2.
... f1 < f2
... 25 + 2.50x < 3.25x
.. 25 < 0.75x . . . . . . . . . . subtract 2.50x
... 25/0.75 < x . . . . . . . . . divide by the coefficient of x
... 33 1/3 < x
You must rent 34 videos or more to make the first club more economical.
Answer:
The slope of line h is -9/7
Step-by-step explanation:
mathematically, for two lines that are perpendicular to each other, the product of their slopes is equal to -1
say we have two lines l1 and l2, the product of their slopes m1 and m2 is -1
Mathematically;
m1 * m2 = -1
now, m1 here is 7/9 , we now proceed to calculate m2
7/9 * m2 = -1
7m2/9 = -1
7m2 = -9
m2 = -9/7
