What is 15/21 subtracted by 5/7 equal ?
Artemon [7]

Answer:

0

Step-by-step explanation:

<u>Step 1:  Make common denominators</u>

What is the LCM of 21 and 7:  7

So, we need to convert both fractions into a 21 denominator.

<em>15/21 * 1/1 = 15/21</em>

<em>5/7 * 3/3 = 15/21</em>

<em />

<u>Step 2:  Subtract the numbers</u>

15/21 - 5/7 is same as 15/21 - 15/21

15/21 - 15/21

<em>0</em>

<em />

Answer:  0

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.

Use the vertical line test to determine whether the graph shown to the right is the graph of a function
Andreas93 [3]

That's not a function.

Since a vertical line hits the graph more than once, if fails the test. (See graph below)

If it is a function, any vertical line you draw can only hit the graph once.

Write the equation of line in slope-intercept form. Line parallel to y=−2x+3 that passes through the point (−100,−100)
GrogVix [38]

Remark

The line you want is parallel to y = - 2x + 3

That means it has the same slope as the given line.  The given line has a slope of  -2

y = -2x + b is what you have so far. Now you have to use the point to get b

y = - 100

x = - 100

Solve for b

-100 = -2(-100) + b

-100 = 200 + b       Notice the sign change. Two minus's make a plus. Subtract 200 from both sides.

- 100 - 200 = b

- 300 = b

Answer

y = - 2x - 100
