Answers

Answer 1
Answer:

Answer:

y=-2x+13

Step-by-step explanation:

slope equation= (y2-y1)/(x2-x1)

(9-3)/(-2-1)=(6/-3)=-2

slope changes by a factor of -2

y=mx+b ... find b, plug in values

9=-2(-2)+b

9+4=b

b=13

CHECK

9=-2(-2)+13

9=-4+13

9=9

CORRECT

A short stop makes an error by dropping the ball. As the ball drops, its height (h) in feet, as a function of time (t) is modeled by h(t) = -16t2 + 3. A slow motion replay of the error shows the play at half speed. What function describes the height of the ball in the replay? (Hint: The function squares the time, so half the time is also squared in the new function.)A)h(t) = -16(0.5t)2 + 1.5B)h(t) = (-16t2 + 3)/2C)h(t) = -16(t/2)2 + 3D)h(t) = -8(t)2 + 3

What is to 3v=v+6? I just in chance this is for homework.

Answers

3v=v+6

Subtract v from both sides

3v-v = v+6-v

2v= 6

Now divide both sides by 2

2v/2=6/2

v= 3


I hope that's help:0


Lets check if the answer is good

all you need to do is to replace v by 3

3v=v+6

3(3)=3+6

9=9

P=2l + 2w

l=6+w
60 = 2l+2w

60=2(6+w)+2w
60=12+2w+2w
60=12+4w
48=4w
12=w

l=6+(12)
l=18
