Find the slope of the line that goes through the given points.

lesya692 [45]

Answer:

Step-by-step explanation:

the formula to calculate slope is

m=( y2-y1)/(x2-x1)

here,

(9,2)= x1 ,y1

(10,6)= x2 ,y2

putting the values in formula , we get

m= (6-2)/(10-9)

=4/1

= 4

dlinn [17]

Answer:

Analyzed and Sketched.

Step-by-step explanation:

We are given $y = \ln(2x) - 2x^2$ .

We need to find the following to sketch the graph.

1) First derivative of y with respect to x to determine the interval where function increases and decreases.

2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

$y' = \frac{1}{x} - 4 x=0$

The roots are x = -1/2 and x = 1/2 but negative one cannot be possible due to logarithmic function.

x = 1/2 is absolute maximum.

$y''=-4 - \frac{1}{x^2}$

So, concavity is always down.

Here, x = 0 is vertical asymptote.

I attached the picture of sketched graph.

Which number is the additive inverse of -4 and 1/4 of a -4 1/4 b -1/4 c 1/ 4 d 4 1/4. What's the answer

Grace [21]

Answer:

The additive inverse of -4 and $\frac{1}{4}$ is 4 and $\frac{-1}{4}$

Step-by-step explanation:

Given numbers -4 and $\frac{1}{4}$

We have to find the additive inverse of the given numbers.

Additive inverse is the number added to a given number that the sum of number is equal to zero. that is $a+(-a)=0$

For given number a = -4

Let number x is added to -4 so that result is 0

$-4+(x)=0$ ⇒ x = 4

Thus, additive inverse of -4 is +4.

For given number a = $\frac{1}{4}$

Let additive inverse be x,

$\frac{1}{4}+x=0$

⇒ $x=\frac{-1}{4}$

Thus, additive inverse of $\frac{1}{4}$ is $\frac{-1}{4}$

Thus, the additive inverse of -4 and $\frac{1}{4}$ is 4 and $\frac{-1}{4}$
