Answer:

11/5

Step-by-step explanation:

We can use the slope formula

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

= (5 - -6)/(-4 - -9)

= (5+6)/( -4+9)

= 11/5

Let's find the slope using the graphing method.

First set up a coordinate system like I have done below.

Now, graph each ordered pair.

Let's call (-9, -6) point A and (-4, 5) point B.

Now remember that the slope or m is equal

to the rise over run from point A to point B.

To get from point A to point B, we rise 11 units and run 5 units.

So our slope is 11/5.

Which function has an asymptote at x= 39

LekaFEV [45]

Answer:

option B : $f(x)= log_7(x-39)$

Step-by-step explanation:

(a) $f(x) = 7^{x-39}$

For exponential function , there is no vertical asymptotes

General form of exponential function is

$f(x) = n^{ax-b}+k$

$f(x) = 7^{x-39}$

In the given f(x) the value of k =0

So horizontal asymptote is y=0

(b) lets check with option

$f(x)= log_7(x-39)$

To find vertical asymptote we set the argument of log =0 and solve for x

Argument of log is x-39

x-39=0 so x=39

Hence vertical asymptote at x=39

RoseWind [281]

Answer:

Step-by-step explanation:

Given

2x² - y ← substitute x = 3 and y = - 2 into the expression

= 2(3)² - (- 2)

= 2(9) + 2

= 18 + 2

= 20

What is the formula for the area of a triangle?

SashulF [63]

The formula to find the area of a triangle is :

1/2 base*height

For instance:

base=4 cm

height=5cm

area of traingle=1/2*b*h

 =1/2*4*5

 =10cm^2

Hope it helps...

Good luck on your assignment

Marguerite is building a box from strips of wood. She needs 78 pieces of wood that are each 29 cantimeters long. The wood comes

Anarel [89]

She will need 3.77 pieces of wood because 1 piece is 6m which is 600 cm and she need 78 pieces of 29 cm so 78*29=2262 then you divide the by 600 and that gives you 3.77 so she realy need 4 sorry i f i got it wrong.

the answer either 3.77

or 4
