Answer: there were 4 cats at the shelter on Monday.

Step-by-step explanation:

Let x represent the number of cats at the shelter on Monday.

Let y represent the number of dogs at the shelter on Monday.

Angel found a record showing that there were a total of 8 cats and dogs on monday. This means that

x + y = 8

The animal shelter spends $5.50 per day to care for each cat and $8.00 per day to care for each dog. Angel noticed that the shelter spent $54.00 caring for cats and dogs on Monday. This means that

5.5x + 8y = 54- - - - - - - - - - - - -1

Substituting x = 8 - y into equation 1, it becomes

5.5(8 - y) + 8y = 54

44 - 5.5y + 8y = 54

- 5.5y + 8y = 54 - 44

2.5y = 10

y = 10/2.5

y = 4

x = 8 - y = 8 - 4

x = 4

Find lim x→3 sqrt 2x+3-sqrt 3x/ x^2-3x. you must show your work or explain your work in words plsss I need help
sineoko [7]

I'm assuming the limit is supposed to be

\displaystyle\lim_{x\to3}\frac{\sqrt{2x+3}-\sqrt{3x}}{x^2-3x}

Multiply the numerator by its conjugate, and do the same with the denominator:

\left(\sqrt{2x+3}-\sqrt{3x}\right)\left(\sqrt{2x+3}+\sqrt{3x}\right)=\left(\sqrt{2x+3}\right)^2-\left(\sqrt{3x}\right)^2=-(x-3)

so that in the limit, we have

\displaystyle\lim_{x\to3}\frac{-(x-3)}{(x^2-3x)\left(\sqrt{2x+3}+\sqrt{3x}\right)}

Factorize the first term in the denominator as

x^2-3x=x(x-3)

The x-3 terms cancel, leaving you with

\displaystyle\lim_{x\to3}\frac{-1}{x\left(\sqrt{2x+3}+\sqrt{3x}\right)}

and the limand is continuous at x=3, so we can substitute it to find the limit has a value of -1/18.
