2,790 is the answer rounded to the nearest ten
Since she has "no more than $40 to spend" we know that the the symbol must be "less than or equal to" 
. Now we can eliminate the first and second choices because they are "greater than or equal to".
Next, we can figure out how to model this situation. There is a flat $5 fee and each song is $2. We can model this with 2s+5 ($2 per son plus $5).
The answer is 
Hope this helps!
Answer:
Leading coefficient is the coefficient of the highest power of x.
is the highest power.
Therefore, leading coefficient = 
Option D
First move the numbers to the other side
x+x = 33-4-7
2x = 22
Next divided both sides by 2 to get x on its own
X=11
Therefore the answer is A
First we need to find inverse function of f(x) which is written in a form of (f(x))^(-1)
That means that we are actually looking for function f(y) and we need to solve this equation for "y"
y=(4x + 1)/3
3y = 4x + 1
4x = 3y - 1
x = (3y - 1) / 4
f(y) = (3y - 1)/4
Now we simply put the value of 3 instead of y and find the answer:
f(y=3) = (3*3-1)/4 = 2
Answer is 2
