Help please Can you clear fractions in an equation by multiplying each side by a common denominator other than the LCD? Give an
Katena32 [7]
Yes   here is an example:_

x/4  +  5/6  =  2

The LCD of 4 and 6 is 12  but we can also multiply through by 24 to clear the fractions:-

x/4 * 24  +  5/6 * 24 = 2 + 24

6x  + 20 = 40

This will give us the same result  if we multiplied through by 12.

PLEASEEE HELP MEEEE<br><br>NO LINKSSS
Artemon [7]

Answer:

\huge\boxed{(2,\ 3);\ (-1,\ 6)}

Step-by-step explanation:

f(x)=x^2-2x+3\to y=x^2-2x+3\\f(x)=-x+5\to y=-x+5\\\\\left\{\begin{array}{ccc}y=x^2-2x+3&(1)\\y=-x+5&(2)\end{array}\right

substitute (1) to (2):

x^2-2x+3=-x+5     add x to both sides

x^2-2x+x+3=-x+x+5

x^2-x+3=5        subtract 5 from both sides

x^2-x+3-5=5-5

x^2-x-2=0\\\\x^2+x-2x-2=0\\\\x(x+1)-2(x+1)=0\\\\(x+1)(x-2)=0\iff x+1=0\ \vee\ x-2=0\\\\\boxed{x=-1\ \vee\ x=2}

substitute the values of x to (2):

x=-1\\\\y=-(-1)+5=1+5=6\\\\\huge\boxed{(-1,\ 6)}\\\\x=2\\\\y=-2+5=3\\\\\huge\boxed{(2,\ 3)}

What is the solution set of {x | x &gt; -3} {x | x &lt; 3}?
givi [52]

x > -3

x < 3

<em><u>-3 < x < 3</u></em>

question didn't mention about "x is real number, or positive, or negative etc".. so we can't say anything more

for example: x can be -2,-1,0,1,2

but if only positive, x can be = 1,2

" " negative, x can be = -1, -2

Hope this helps ^-^

SHOW ALL WORK BUT KEE IT SIMPLE AND EASY TO UNDERSTAND:)
7nadin3 [17]
To do this problem, you need to use a process called completing the square. Let me explain:  

To complete the square on the function f(x) = x² + 8x +13, first group the first two terms in (  )  and leave some space at the end as follows:
f(x) = (x² + 8x          ) + 13  Now our next step is to fill in the space and adjust our expression on the right hand side of the function.  To do this, we take half of the middle number 8 and then square it:  so 4² = 16 and we fill in our space inside the ( ) with this value 16;   
f(x) = (x² + 8x + 16) + 13  now what we have done is to increase the overall value of our expression on the right by 16, but we want the overall value to remain the same.  To fix this we simply need to subtract 16 at the end like this:  f(x) = (x² + 8x + 16) + 13 -16   we can simplify and get the following.
f(x) = (x² + 8x + 16) - 3   At this point we're almost done.. All we need to do now is to rewrite the what is in the parentheses in a slightly different form.  Here is what it will look like:  f(x) = (x + 4)² - 3  notice all I did was take the sum of the square root of x² and the square root of 16 originally in the (  ) to get then new expression inside the ( ) and then square that  ( )²

Now this is a nice form to have because you can get the vertex straight from this form.. IN FACT this is called vertex form or (h,k) form for short.  In general the form is f(x) = a(x - h)² + k  don't worry about the 'a'  for now.. you might see that in our case it is just 1 and will not effect our equation.  You only have to consider this if the original leading coefficient of the quadratic is not 1 to begin with...

So you can see that our vertex is (-4,-3)  
Hope this is helpful, but if you have questions let me know.

1) Find the missing side.
kari74 [83]

Answer:

25inch

Step-by-step explanation:

Ok so there is something called a Pythagorean theorem.

It's a²+b²=c²

It works on right triangles

C is the longest side or the side not touching the right angle

and a and b is the other 2 sides

so the missing side is 24²+7²=Missing side or c²

24²=576 and 7²= 49  

576+49=625

\sqrt{625}=25
