Evaluate the limit, if it exists. Show work. lim┬(x→5)⁡〖(x^2-3x-10)/(2x-10)〗
BARSIC [14]

Hello, first of all we can notice that

5^2-3*5-10=25-15-10=0

and

2*5-10=0

and 0 divided by 0 is undetermined.

So, we need to factorise and simplify first.

x^2-3x-10=(x-5)(x+2)\\\\\text{Because we already known that 5 is a zero...}\\\\\text{... and the sum of the zeroes is 3 = 5 - 2 and the product is -10 = 5 * (-2).}

For x different from 5, we can write

\dfrac{x^2-3x-10}{2x-10}=\dfrac{(x-5)(x+2)}{2(x-5)}=\dfrac{x+2}{2}

So, the limit when x tends to 5 is

\dfrac{5+2}{2}=\boxed{\dfrac{7}{2}}

Thank you

Answer:

$4.5

Step-by-step explanation:

Hot dogs=h

Cheese burgers=c

2h+3c=20

2h+5c=29

There are two ways to solve-

1. Elimination- multiply the bottom by -1.

2h+3c=20

-2h-5c=-29

-2c=-9

c=4.5

2. Just move 2h, and you get 2c=9, 4.5

What would the answer be to 4x-6y=36 graphed
xz_007 [3.2K]

Answer:

  see the attachment

Step-by-step explanation:

It is convenient to graph this equation using the x- and y-intercepts.

The x-intercept is found where y=0, so ...

  4x = 36

  x = 9

The y-intercept is found where x=0, so ...

  -6y = 36

  y = -6

<em>Graph the two points (9, 0) and (0, -6) and draw a line through them</em>. The graph is shown below.
