Answer:
3x^2-4x+20/x^2-5x .
Step-by-step explanation:
The given rational expression is:
3x/x-5 - 4/x
Hence to find the difference of the rational numbers we have to take the L.C.M of the denominators:
Thus the L.C.M of x-5 and x is (x-5)(x) and then solve for the numerator:
x(3x) - 4(x-5)/(x-5)(x)
Now solve the numerator and denominator:
3x^2-4x+20/x^2-5x
Thus the answer is 3x^2-4x+20/x^2-5x ....
Sorry I'm not really sure what you're asking for, but I think you want the line, so here
The circumference is usually three times as much as the diameter
Answer:
Step-by-step explanation:
y=ar^x
(ar^5)/(ar^3)=72/432
r^2=1/6
Since r^2 < 1
This is exponential decay.
<span>We can represent the number of pies she makes to be x.
We also need to add $30 to the equation to take the baking supply cost into consideration.
The Cost can be represented by C.
C = 5x + 30 is the equation to use to determine the Cost! 5 times the number of pies she makes plus the $30 for baking supplies!
If we look at just the cost when she doesn't sell any pies, we can say x = 0
That means C = 5(0) + 30 or C = 30, it means that she has to pay $30 or the Cost is $30 when she sells no pies.
This makes sense since the baking supplies were $30.
Are you with me so far?</span>
