Evaluate x/y if f x = 14 and y=-2

Ksju [112]

Answer:

-7

Step-by-step explanation:

First, we need to substitute x in as 14 since that is what x is equal to.

1. x / y => 14 / y

Next, we need to substitute y in as -2 since that is what y is equal to.

2. 14 / y => 14 / -2

Now to solve it;

3. 14 / -2 => -7

So now we now that x / y equals -7 when x = 14 and y = -2.

Graphing Natural Exponential Functions In Exercise,sketch the graph of the function.See Example 1.

serg [7]

Answer:

See the graph and explanation below.

Step-by-step explanation:

For this case we have the following function:

$f(x) = e^{1-x}$

We can calculate some points in order to see the tendency of the graph, we can select a set of points for example $x =-2,-1.5,-1,0,1,1,5,2$ and we can calculate the values for f(x) like this

x=-2

$f(x=-2) =e^{1+2}= e^{3}=20.086$

x=-1.5

$f(x=-1.5) =e^{1+1.5}= e^{2.5}=12.182$

x=-1

$f(x=-1) =e^{1+1}= e^{2}=7.389$

x=0

$f(x=0) =e^{1-0}= e^{1}=2.718$

This point correspond to the y intercept.

x=1

$f(x=1) =e^{1-1}= e^{0}=1$

x=2

$f(x=2) =e^{1-2}= e^{-1}=0.368$

We don't have x intercepts for this case since the functionnever crosses the x axis.

And then we can see the plot on the figure attached.

What is the answer for 1/4 ( 12x + 24 ) -9x

Gekata [30.6K]

The final expression is $-6x+6$

Step-by-step explanation:

The expression that we have is

$\frac{1}{4}(12x+24)-9x$

In order to solve the expression, we start by applying the distributive property to the bracket. We get:

$\frac{1}{4}\cdot 12x + \frac{1}{4}24 -9x$

Simplifying,

$3x+6-9x$

Now we add the two terms in x, and we find:

$(3x-9x)+6=\\-6x+6$

Which is the final expression.
