Answer:

look below but sorry that i dont know part b

Step-by-step explanation:

y = 5/2x-3

slope=5/2 y-int = -3

y=x-9

slope=1/1 y-int=-9

y=5x

slope= 5/1 y int=0

y=-1/2x +5

slope=-1/2 y-int= 5

plzzzz plzplz mark me brainliest thank you!!!!!!!!!!!!

Find the average rate of change for f(x) = x2 − 3x − 10 from x = 4 to x = 6. A) 5 Reactivate B) 7 C) 9 Reactivate D) 11

White raven [17]

Answer:Rate of change is 7

Option B is correct.

Step-by-step explanation:

We need to find the average rate of change for $f(x)=x^2-3x-10$ from x = 4 to x = 6

The formula used to find average rate of change is:

$Rate\,\,of\,\,change=\frac{f(b)-f(a)}{b-a}$

Where b = 6 and x = 4

Finding f(6):

$f(x)=x^2-3x-10\\f(6)=(6)^2-3(6)-10\\f(6)=36-18-10\\f(6)=36-28\\f(6)=8$

Finding f(4):

$f(x)=x^2-3x-10\\f(4)=(4)^2-3(4)-10\\f(4)=16-12-10\\f(4)=16-22\\f(4)=-6$

Now Putting values:

$Rate\,\,of\,\,change=\frac{f(b)-f(a)}{b-a}$

$Rate\,\,of\,\,change=\frac{8-(-6)}{6-4}\\Rate\,\,of\,\,change=\frac{8+6}{2}\\Rate\,\,of\,\,change=\frac{14}{2}\\Rate\,\,of\,\,change=7$

So, Rate of change is 7

Option B is correct.

A turtle can walk 1/12 of a kilometer in an hour. The turtle is 1/5 of a kilometer away from a pond. At this speed how long will

Cloud [144]

Answer:

2.4 hours

Step-by-step explanation:

Get common denominators -

1/12 x 5/5 = 5/60

1/5 x 12/12 = 12/60

The turtle walks ata 5/60 a kilometer an hour.

divide remaining time by 5/60

(12/60) / (5/60) = 2.4 hours

HELP ASAP!!! explanation requiredd!

(7x-5)+(3x-15)=180°

10x-20=180

10x=200

x=20

(3x-15) + E = 180

3(20)-15 + E = 180

45 + E = 180

E = 135°

FG = EH = 2(y+1)
