Use graphs and tables to find the limit and identify any vertical asymptotes of the function

1 answer:

5 0

You want to do exactly what this says, use the graph. If you were to just plug the 4 into the equation, you would end up with an undefined fraction. However, if you graph it in your calculator, take a look at what is going on with the graph as the x approaches 4 to easily find your limit. Remember to put parenthesis around the denominator when putting it into the calculator so it will graph correctly. Also, remember to write your asymptote as a linear equation, not just a number.

Express {x+1}{2x-3} as a trinomial.

Marizza181 [45]

Answer:

$2x^2 + 5x + 3$

Step-by-step explanation:

First, expand the original equation:

(x + 1)(2x + 3)

$2x^2 + 3x + 2x + 3$

Now simplify:

$2x^2 + 5x + 3$

And that's your answer!

Y=-2x graphed. had to put more words to put this out

timurjin [86]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))

$slope=\frac{rise}{run}$

Rise is the number of units you go up(+) or down(-)

Run is the number of units you go to the right

y = -2x

This has a y-intercept of 0, so the line intersects the y-axis/goes through the origin at (0,0)

The slope is -2 or $\frac{-2}{1}$ , so from each point, you go down 2 units, and to the right 1 unit.

What is the value of y?

NNADVOKAT [17]

Answer:

y = 40

Step-by-step explanation:

Lets make an equation to represent the sum of the angles:

We know that the sum of angles of triangles equals 180 degrees. So based on this knowledge, the equation is :

2y + y + 10 + 50 = 180

Now we simplify:

2y + y = 3y

10 + 50 = 60

So our new equation is 3y + 60 = 180

Now all we have to do is simplify:

3y + 60 = 180

3y + 60 -60 = 180 - 60

3y = 120

3y / 3 = 120 / 3

y = 40

So the answer is 40 hope this helped
