What is the end behavior? 10 points!!

Colt1911 [192]

Given:

The given function is:

$f_1(x)=-3\cdot 2^{x-5}-4$

The graph of the function is given.

To find:

The end behavior of the given function.

Solution:

We have,

$f_1(x)=-3\cdot 2^{x-5}-4$

From the given graph it is clear that the function approaches to -4 at x approaches negative infinite and the function approaches to negative infinite at x approaches infinite.

$f_1(x)\to -4$ as $x\to -\infty$

$f_1(x)\to -\infty$ as $x\to \infty$

Therefore, the end behaviors of the given function are:

$f_1(x)\to -4$ as $x\to -\infty$

$f_1(x)\to -\infty$ as $x\to \infty$

A line goes through the points (5, -1) and (7, -5). What is a possible equation to a new line that is perpendicular?

Leya [2.2K]

Ok, so you are given an equation in standard form, 5x+4y=2, and a point, (7, 5). You are being asked to write the equation for a line that is parallel to the equation in standard from, and that includes the point (7, 5).

First, let's start by finding the slope of your new line. We know that it needs to have the same slope as 5x+4y=2, because parallel lines have the same slopes. To do that, we need to put the equation into slope-intercept form (y=mx+b), which means we need to isolate the "y."

5x+4y=2

-5x -5x (subtract 5x from both sides to move it to the right side of your equation)

4y = 2 - 5x

/4 /4 /4 (divide all the terms by 4 to get "y" by itself)

y = (1/2) - (5/4)x ... I suggest leaving your slope as a fraction.

Now, we know that our slope, m , is going to be -(5/4).

Next, we are going to use our slope, -(5/4), and point, (7, 5), to find the b-value (y-intercept) of your new line. Let's plug in what we know:

y = 5

m = -(5/4)

x = 7

y=mx+b

5=(-5/4)(7) + b -> I plugged in what we knew for y, m, and x.

5 = -(35/4) + b -> I multiplied the numbers in the numerator (5 x 7) to get 35/4

20/4 = -(35/4) + b -> I converted 5 into a faction with a denominator of 4 by multiplying by (4/4)

+(35/4) +(35/4) -> I add (35/4) to both sides to isolate b

55/4 = b ... or b = 13.74

Answer:

m = -(5/4)

b = 13.75

Rounding decimals 32.60

UNO [17]

Well, assuming that you need to round to the nearest whole number, what is six closer to? 0, or 10? The answer is 10. Therefore, you would round up to 33. Hope this helps!

Can some one please help me.

Otrada [13]

X = 29 and y = 101.

To find this, you need to set up an equation.

6x - 95 = 79. Once you solve this, x would equal 29.

Since 6x - 95 and y are on a straight line, they would have to equal 180. So you make another equation except you plug in 29 for x this time.

6(29) - 95 + y = 180. Once you solve this, y would equal 101.
